Field Trip!

Filed under: — stan @ 8:50 pm

A few weeks ago, Sue Hough sent an email out to the office to see who would be interested in a field trip to tour the San Andreas Fault in the Antelope Valley, a bit north of Los Angeles. The sights would be taken from her book, Finding Fault in California. As it turned out, there was quite a bit of interest. In the end, it was enough interest that we rented a 24-passenger bus and driver for the day so we could take the trip.

We met at the office early Wednesday morning, and then we headed out. We went past JPL, which is located right on the trace of the Sierra Madre Fault, and has a very nice, steep scarp right behind it. Our first real stop was the small fault scarp next to the McDonald’s at 1955 Glenoaks Blvd in San Fernando. This scarp was formed in the 1971 San Fernando Earthquake. I took the bike club there to see the scarp last June.

Continuing on up the freeway, we went through the 5/14 freeway interchange. This interchange fell down in the 1971 earthquake. It was rebuilt, and then fell down again in the 1994 Northridge Earthquake. Then we went up the 14 freeway, through the mountains, coming out in Palmdale. We went one exit farther up the freeway than we needed to, since that let us go through a somewhat-famous road cut on the freeway. It’s where the freeway crosses the trace of the San Andreas Fault, and in that cut, the rock layers look particularly jumbled and twisted from the motion of the fault.

Heading east out of Palmdale, we went along the northern edge of the San Gabriel Mountains. We stopped for a photo-op at a place where some people put up signs on the road to mark the trace of the fault. Makes it really easy to find, when there’s a big sign pointing it out. This site was very near where Kerry Sieh did his first trenching studies on the fault, back in the ’70s.

A little while later, the road started to climb into the mountains, still following the trace of the fault. We stopped at another road cut where the cut went right through the fault gouge. The side of the cut was basically packed sand and pulverized rock. Digging into it with our hands, there were some solid pieces of rock buried in there, but as Sue showed us, those solid pieces were actually shattered, and we could crumble them to sand in our hands. We also saw a tree there that was kind of bent at the top. There has been some research done on trees in that area that grow along the fault line. There are trees that show signs of having been broken off in past earthquakes.

In Wrightwood, we took one small side trip to look at some recent debris flows, and how the town has attempted to guide future debris flows to minimize damage to the town.

Coming down the east side of the mountain from Wrightwood, we ended up coming out by the 15 freeway in Cajon Pass. We took one more side trip to see Lost Lake, which is a small sag pond on the fault there.

This made for an interesting day of sightseeing. Have I mentioned lately that I really like my job?


Chicago 2014

Filed under: — stan @ 11:08 pm

This weekend was our yearly trip to Chicago to visit, play tourist, and to climb the stairs up the Sears Willis Tower. After the ordeal we had last year on this trip, we were hoping that things would go smoother this time. Last time, our trip out was delayed a day by the shootings at LAX, so the odds seemed to be in our favor this time. We got to the airport at about 9:45 for our 11:05 flight, and everything seemed all right. But almost immediately, they said that the flight was delayed to 12:15. And a little while later, that was pushed back to 1:20. So we had some lunch and waited some more.

The next time I checked, our flight was listed as ‘Canceled’. It was about this time that we started to hear talk of bad weather in Chicago, and that air traffic bound there from all over the country was being delayed. I went to one of the check-in kiosks to see what I could find out. It told me that we’d been rescheduled for a new flight at 3:41. So that didn’t seem too bad. It was about this time that I finished reading the book I’d brought along. And since we weren’t going anywhere any time soon, I went looking for something else to read. I picked up a copy of The Martian and started reading it.

When it came time to get on the airplane, as soon as we were all aboard, they said that we were going to be delayed another hour, and that if we wanted to, we could get off and walk around some. But soon after that, they announced that we were going to push back from the gate. We weren’t leaving. But they needed the gate for another flight coming in. So we got to sit in the airplane for about an our, parked out on the taxiway. I was glad that I’d found an entertaining book to read, otherwise the waiting would have been even worse.

We finally got under way at about 5:30. The flight was pretty uneventful, and we got to Chicago at about 11:45 Friday night. By now, it was far too late to go for dinner, and almost everything in the airport was closed. So we walked over to the Airport Hilton, where they had a bar and restaurant still open. We stayed there for a short time, and then rode the train to our hotel.

Saturday morning, we went downstairs and got breakfast. Then we rode the train downtown to pick up our race packets at the Sears Willis Tower. And after that, we had to immediately head over to the Weird Chicago tour we’d signed up for. It was three hours on a bus, traveling around the city, visiting sites significant to the city’s Mob history. It made a nice companion piece to the time we went to the Mob Museum in Las Vegas. After the tour, we got on the train and headed over to the West Loop neighborhood to meet up with all our stair climbing friends for dinner.

On Sunday morning, we got up bright and early and headed downtown. We got to the building at about 8:15, and I got right in line to climb. There was kind of a lot of traffic in the stairwell. On several occasions, I had to push through groups of people. There were a few people who were climbing who were obviously handicapped, using canes and such. For them, I went around the outside. But they were going slow enough that going around wasn’t a big problem. For everyone else, I just pushed through, up the inside railing.

I managed to maintain my target pace of five floors per minute up to about 65 or so. Then I started to slow down a bit. In the end, I made it to the top in 23:10. Not blazing fast, but not bad, either. That works out to something like 4.6 floors per minutes average. It was pretty close. I was originally planning on going back down and walking up with Kathleen, but my knee was not feeling good, so I just sent her a message that I’d just stay at the top until she got there. I took a guess at when she’d get there, and I made a point to go over near the door then. And when she came out, she started crying. It was a hard climb. The stairs there are steeper than most normal office building stairs, and psychologically, that’s hard. But she perked up pretty fast. We went around and looked at the view, and we got our picture taken on the south side of the building, where the sun came in. That way, we could get a picture of us with the view, but without us being just silhouettes against the window. Most of the time, when people try and take those pictures, it ends up looking like Witness Protection climbed the tower.

After the climb, we went back to our hotel and got cleaned up. After that, we went back downtown to meet up with my old friend Laura. She’s in the restaurant business and recently moved to Chicago to oversee the setup and opening of the restaurants in the soon-to-be-opened Virgin Hotel there. We had a nice lunch, and after that, we went to Union Station to get the train to Libertyville to visit Kathleen’s aunt and uncle there. We spent the night at their house, and we all went to the Chicago Botanic Garden the next day. And after that, they dropped us off at O’Hare for our flight home.

Our flight home was not delayed like Friday’s flight out. In fact, the delay coming back was only about an hour or so. Still delayed, but nowhere near as much as on Friday. So all told, it was a fun trip, aside from the actual traveling part. And yes, I liked The Martian. It’s not that often I chew through a 350+ page book in under 24 hours.


Mt Baldy 2014

Filed under: — stan @ 7:33 pm

Last year’s government shutdown involved a good bit of hiking in the local mountains. Since there was no furlough-cation this year, we had to take a weekend day to go climb Mt Baldy. We wanted to do it before November, since it’s going to get cold up there, and there could be snow. So today was the last available day in October.

Like last year, I went with Karina from my office. We went up to Manker Flat to the trailhead. On the way up there, I collected a new animal crossing sign for my collection. When we started up the trail, we got a nice view of San Antonio Falls. Even with the drought, there was still a little bit of water going over the falls. Just hearing running water is such a novelty for us these days. We also heard a woodpecker, and we were lucky enough to see it going at the trunk of a dead tree.

Because it was Saturday instead of a weekday, there were a lot of people on the trail. That was all right. It was just strange, since last year’s hikes left me with the impression that all these trails are deserted. There was a small crowd at the hut about halfway up the mountain. And a very friendly Golden Retriever named Butter, who begged snacks from everyone there.

Leaving the hut, we walked across the bowl to the place where the trail climbs steeply up the ridge to the south of the summit. In the bowl, there is a big field of boulders, and it’s pretty obvious that they all fell from the crags at the top of the ridge. I couldn’t help but wonder what that must have sounded like.

The last part of the climb to the summit was hard. Just as hard as it was last year. But we made it, and we settled in for lunch on top of the mountain. Just us and about fifty other people. At least with that many people up there, there were lots of people for the bees to bother, so they didn’t bother us so much as when we were the only ones there.

On the way down, I stopped to take a picture of the waning crescent moon hanging just over the rocks below the summit. And I also got some pictures along the trail. I’ve decided that there are parts of the Devil’s Backbone trail that really give me the willies. But that’s all right. We made it down just fine. At the ski area, they were getting ready for ski season. There were some crews practicing rescuing people from the chair lift, and there were CPR dummies spread out on a blanket nearby. We went in the restaurant so I could refill my water bottle. And we got a picture, looking back up at the summit. Then we started down the service road back to Manker Flat.

Like last year, the service road seemed to go on forever. It’s long. But I was expecting that this time, so it was all right. And we made it back to the car just fine. According to my little GPS thingy, it was 4 1/4 miles from the start to the top, and it was 10.9 miles for the whole loop. Good fun.


A lot of Nowhere

Filed under: — stan @ 6:49 pm

Last year, I finally got to do the hike to “The Bridge to Nowhere”. And today I got to do it again. The main difference this time is that it was a Saturday, rather than a Friday, and there was no government shutdown in effect. Last year when we did this, the place was deserted. We saw just a handful of people on the trail. But today, when we got to the trailhead, we had to park about a quarter-mile back down the road, since the little parking lot was completely full.

I’d gone up there with my hiking friend Kathy, and we were going to meet up with my stair-climbing friend Crystal and her boyfriend Barry. When I saw all the cars there, I thought it was going to be hard to find them. But when we parked, it turned out they were in the car right in front of us. That was convenient.

We started out down the trail. The first time, I didn’t really know what to expect, so it was easier this time. I knew the basic pattern for following and finding the trail, and we made good time. It only took us a little over two hours to make it to the Bridge. When we got there, the bungee-jumping people were out in force. It was a far cry from the deserted bridge I remember from last year. We crossed, and then followed the trail down into the gorge below the bridge so we could watch the bungee jumpers. Here’s a sample:

We had lunch down there in the gorge, and then we headed back. The hike back went pretty fast. It was a perfect day, and all around, it was a fun time.


That’s a big telescope

Filed under: — stan @ 5:50 pm

Tonight’s adventure was a trip up Mt. Wilson with the Obscura Society for an evening of looking at the stars with the 60-inch telescope. We headed up to the top of the mountain, where we were met by our guide, Shelley Bonus. She led us in to the telescope and told us the history of it while we were waiting for nightfall. And once it was fully dark, we were able to get started. And since Matt from the Obscura Society had suggested bringing baked goods along for the evening, I brought a batch of my blue-ribbon-winning chocolate cookies. They disappeared fast, so I guess that’s a good sign.

Shelley explained that the telescope has its strong and weak points. It’s great for observing stars and small star clusters. Because it has such a long focal length, it is best run at what would be considered impossible magnifications for a small amateur telescope. There was one night back in 1997 when the air was very still and I was able to run my 8-inch Celestron up to 300X. But normally, about 100X is as far as I can go. But with the 60-inch, we were routinely running close to 400X, and the image in the eyepiece was rock-solid and clear.

We started out with Epsilon Lyrae. Splitting the two double stars is a test of the resolving power of any telescope, and the big telescope did it easily. And while we were in the neighborhood, we had a look at M57, The Ring Nebula. This is another thing I’ve looked at with my telescope, but it was much bigger and more detailed here. We also had a look at the Dumbbell Nebula, but it wasn’t such a great sight. It’s a relatively large object, so it didn’t fit well into the field of view a high magnification.

We looked at a couple of globular clusters, which were very nice. They actually looked like balls of stars, rather than the round patches of fuzz they look like in smaller telescopes. And we ended the evening with a look at Neptune. It was nice and big and blue, and its moon Triton was clearly visible. Triton has a visual magnitude of about 13, which is beyond the reach of my little 8-inch telescope, but it was obvious here.

All in all, it was a good evening of nerdy fun.

Addendum: I didn’t make the connection until the next day, but I knew Shelley before. Back in 1990, I took a class at UCLA Extension called “How to Perform Stand-Up Comedy”, and she was the instructor. But because it had been so long, and being in a completely different context, I didn’t put it all together at the time. But in any event, it was a very weird coincidence.


Mt Lukens

Filed under: — stan @ 3:20 pm

Mt Lukens is the highest point within the city limits of Los Angeles, and as such, it’s home to a lot of communications equipment for the Department of Water and Power, and other things like that. Since the seismic network uses some of the DWP network, we have a microwave link up there from the Seismo Lab. So I was curious to see it. I read a post on a hiking blog about climbing this mountain, and it sounded like a fun hike.

Karina is training for the New York Marathon, so she was busy going running, so Kathy and I did the hike. We started out from Deukmejian Wilderness Park in Glendale. The trail started out up the wash in the park, but quickly turned right and went up a steep ridge. The first couple miles were very steep, and pretty soon we were above the clouds. It was kind of gray and overcast down below, but it was a perfect day up on the mountain.

At the top of the ridge, the trail turned into a fire road for a bit along the top of the ridge before we met up with the Mt Lukens road. From there, it was an easy mile or so up the road to the top. At the top, we spent a few minutes looking at the view. To the south, it was just clouds, with some other mountains poking up through them, and to the north it was clear.

Going down, we took the Rim of the Valley trail, which came down a different ridge a bit west of the ridge we’d hiked up. The only really tricky part of the trip down was finding the turnoff, since the main trail goes down to Haines Canyon, and we needed to take the cutoff trail to get back to Deukmejian Park. The saving grace of the southern California mountains is that there are basically no trees, so it’s easy to see the different trails and where they go. So we turned off and headed down toward the park.

At one point, the trail went down into a canyon where there was actually a small stream. It was just a trickle, but it was actual running water. And there were big trees growing at the bottom of the canyon. From there, we had to climb up and out to get over the next ridge, and then we could see where we’d started. The last part of the route was an easy walk back down Dunsmore Canyon to where we started. In the end, it was nearly 10 miles in all, but it was a nice day, so it was a good time.

Here’s the route map:


Tower running

Filed under: — stan @ 9:47 pm

Friday evening was time for the stair climb up the U.S. Bank building in downtown Los Angeles. 75 floors, and 1,664 steps to the top. I know. I counted them.

In contrast to past years, I wasn’t thinking about trying to prove anything this time. I just wanted to go up in a non-embarrassing time, and to enjoy seeing all my stair-climbing friends in the process. So my goal was to do about 15 minutes or so, since that’s a reasonably relaxed pace in my book.

I had to leave work a little early to get downtown for my schedules 4:00PM start time. When I was getting signed in, I got a message from Kathleen that she was starting up the stairs. Her start time was 3:30, so I thought that we might come out at the top at close to the same time. So I got changed and headed down to the starting line. When I got there, I was the only one there. That was decidedly weird. Usually, there’s a long line to wait in, but I just walked up to the start and went in.

I was aiming for five floors per minute, and I was able to maintain that pace pretty easily. Unlike other years doing this, there was very little traffic in the stairwell. One guy passed me soon after the start. I caught and passed him again about 30 floors later. And along the way, I passed a handful of people. I passed Kathleen somewhere in the high 50s. At that point, I was still on my pace, but my shoe had come untied at about 35, and by 58, I had to stop and retie it before it fell off. So I lost about 30 seconds doing that. But then I just continued on, and I came out on top with a time of something like 15:34. A little slower than I’d wanted, but, as I said, I’m not trying to prove anything.

After just a few minutes, Kathleen came out on the roof. We looked at the view and took a few pictures, and then headed down the other stairway to the big open space on 71. We had some water, took some more pictures. And then we took the elevator back down to the ground.

At the bottom, I saw some friends who had come up from Orange County to do the climb. So I joined them to go up again. By now, there was a line at the start, so we got to talk for a while while waiting to go. And then I went up for the second time. Part-way up, I got a message from Morgan that she, Jason, and Irving were all there. They had finished their first climb, and they were thinking of going again. So I said I’d go again with them as soon as I got back down. And when I got back down, the four of us got back in the line, and we headed up again. It’s kind of nice to take a leisurely-paced climb up the building. Not that there’s much scenery or anything, but it’s sort of like hiking up an industrial-looking mountain.

After three climbs up the building, I was done, so we got changed and headed home. It was a fun evening.


what if?

Filed under: — stan @ 5:52 pm

On Sunday afternoon, we took a trip to Santa Monica to go to a talk and book-signing with Randall Munroe of XKCD. He has a new book out: What If?: Serious Scientific Answers to Absurd Hypothetical Questions. It’s a collection of his what if? columns, and it’s all very entertaining.

The basic format was a conversation between Randall and Wil Wheaton. They talked about the book, about science in general, told stories, and took questions from the audience. It was a fun time, and at the end, we all lined up to get our books signed by Randall. And I got to thank him for the little bit of geek fame I got from when he mentioned my Pet Project in the mouseover text for this cartoon:


The Mt Lowe Railway tour

Filed under: — stan @ 12:26 pm

After doing the hike up Mt Zion two weeks ago, I was ready for more. Karina couldn’t go today, but Kathy could, so we made plans to meet up and do part of the Mt Lowe Railway tour. When I did this last fall with Karina, we walked up Echo Mountain and then all the way up to the location of the old Alpine Tavern. This time, the plan was to go not quite so far, but to make a loop of it.

We met up at the top of Lake Ave, by the Cobb Estate gate. From there, we walked down Loma Alta Dr to Chaney Trail and walked up that road to the actual start of the trail, which was the Sunset Ridge fire road. At the start, there was a sign with a map, showing the route of the old railroad, and some of the points of interest along the way. We took the fire road up the ridge to the Cape of Good Hope, where the fire road meets up with the old Mt Lowe Railway roadbed. From there, we turned and took the railroad route back down through Flores Canyon to Echo Mountain.

At Echo Mountain, we found a small spot of shade under a tree and had a look around. We were joined by Stella, who was hiking with another group. Like most dogs, she was happy to find a bit of shade to lie down in. Looking to the southwest, we could see the big plume of smoke from a brush fire burning in Silverado Canyon in Orange County.

On the way down, there was a sign asking for people to go to Facebook and ‘like’ the Friends of Echo Mountain. Apparently, if they get enough likes, they will get some sort of funding to do trail maintenance and other good things.

By the time we got down, it was getting pretty hot, but since we had started out at 7:15AM, it was only about 11:15 when we got down, so we missed the hottest part of the day. So overall, it was a fun hike.

Here’s the route map


Mt Zion

Filed under: — stan @ 2:43 pm

After doing a short ’shakedown’ hike last summer, I think I’m up for hiking more again. So today was the day. I met up with Karina and Kathy and we headed up to Chantry Flat. Karina knows a route from there that goes up Santa Anita Canyon, over the summit of Mt. Zion, and then back down another part of the canyon. And perhaps most importantly, since Santa Anita Canyon usually has a small stream flowing in it, most of the route was through forest, so there would be shade.

We tried to get an early start, since parking is very limited at Chantry Flat. We got up there before 8:00, but we still ended up having to park about 1/2 mile back down the road. Then we started out, walking back up to Chantry Flat, and starting down the trail, which began with about 1/2 mile downhill into the canyon. At the bottom, we saw where the stream should have been, had we not been in the middle of an epic drought here. What was supposed to be a flowing stream was just a stream bed, with occasional little pools. Most of the bed wasn’t even visibly damp. Which is why I thought the guy with the fishing pole was being perhaps a bit too optimistic. But he did find a fair-sized pool, although I’m not sure there were any fish in it.

We hiked a good way up the canyon, and then we turned and headed up the side of the canyon, toward Mt. Wilson. There was a little side trail that went up to the top of Mt Zion, which was nice. it was one of the few times we came out of the trees and got a view. After that, we went back to the trail junction and sat down in the shade to have our lunch.

The trail back switchbacked down the south face of Mt Zion. There were some spots where there was a view, which was nice, but it was also getting pretty hot by then. At the bottom of the canyon we came through Hoegees Campground, and a bit farther along, we saw a small cave in the rocks. I went in it a bit just to see how far it went. Finally, the trail came out back at the junction at the bottom of the canyon, below Chantry Flat. From there, we had to walk back up to the road, and then down the road to where we’d parked. In all, it was about 8 1/2 miles or so.
