And then this happened…

Filed under: — stan @ 10:47 pm

Last September, we took a trip to Santa Cruz to move Lucinda into her new home-away-from-home at UC Santa Cruz. And today was the other bookend for that experience.

A couple weeks ago, Lucinda asked if I would come to Santa Cruz to help her move out and bring her home. At first I thought this would make for a grueling day or two days, but at the same time, I realized it was an opportunity to spend a day with her. As she’s growing up, opportunities for things like that become more rare. So I worked out a plan. I would fly to San Jose in the morning, and then rent a car there. I was able to set it up with Hertz that I could rent the car at San Jose Airport, and then bring it back the next day to their office in Pasadena. So the plan was to pick up the car and drive it over the hill to Santa Cruz. Then we loaded up all her stuff into the car. We stopped off in downtown Santa Cruz for lunch, and then we headed for home.

We took the 101 south for a good bit of the trip. We had to take some small roads to pick up the 101 in Prunedale. Then we went south on the 101 for what seemed like forever. Along the way, I told Lucinda that I wanted to take a short side trip to the Carrizo Plain to see Wallace Creek. That’s a very desolate and remote place that is famous among seismologists. To get there, we had to take Highway 58, which I expected to be like Highway 46 that I took home last fall. But no. Highway 46 was divided and almost like a freeway, while Highway 58 was like a narrow, winding country road. We took that for a very long time before we came to the turnoff. That was a small, but well-paved road. But we were only on that for a short distance before we had to turn off onto a small dirt road. At least it was pretty well-graded, so it wasn’t a big deal. But as city people, we’re just not used to be out in the middle of nowhere and being all alone for as far as we could see in any direction.

There’s a small guest book at the site, and it looks like it gets a visit about once every week or two on average. I wrote us into it, and then we walked up the trail to go see the famous creek. Well, actually, ‘creek-bed’. It only has water in it on fairly rare occasions when it rains. But it was impressive. The channel is pretty deep, and the offset where it crosses the fault is really obvious. The sign said that they figured out that the offset of that creek-bed represents 3,800 years of earthquakes, and that led to knowing that the San Andreas is moving an average of about 1 1/3 inches a year.

We walked a little bit down the trail to see a pair of smaller offset creek-beds. They were channels that were offset by about 30 feet in the 1857 Fort Tejon earthquake. They weren’t as big and obvious as Wallace Creek, but it was still impressive to be able to see how much the ground moved in one event in 1857.

When we finished at Wallace Creek, we continued east on the 58 to get to the 5 freeway at the Buttonwillow offramp. That’s a little cluster of gas stations and food places to cater to people traveling between northern and southern California. We had some dinner there, filled the car up with gas, and then we headed home. And yes, it was nice to get to spend a day with her doing this.

Spahn Ranch with Atlas Obscura

Filed under: — stan @ 2:05 pm

Today I got to go on yet another Atlas Obscura tour, this time of Spahn Ranch. This was a movie ranch a long time ago, and later was notorious for the Manson Family living there for a time in 1969. And now it’s a county park. A few years ago, I took Lucinda on the Dearly Departed Helter Skelter tour, so this was sort of a companion piece to that.

We walked up the hill to the back of the ranch, where there were a couple of rusted hulks of cars that were stolen and abandoned there in 1969. Apparently, they would steal cars to get the engines, which they used in building dune buggies.

Next, we walked down to the large flat area next to the road. This was where the Spahn house had been. When the land was converted into a park, the county came in and covered that whole area with several feet of new dirt, I suppose to discourage people from hunting for artifacts there. Then we walked down into the creek-bed. There were large trees down there, as well as the famous little cave where Life magazine staged a photo of the Manson Family in 1969. And of course, we all had to get photos sitting in front of the little cave. Overall, there wasn’t a lot here that I hadn’t heard about before, but the whole point was to get to see the places where it happened.

Earthquake Tour Again

Filed under: — stan @ 7:11 pm

This Saturday was the fourth time I’ve been part of leading the San Andreas Fault tour with Atlas Obscura. The last time I did this was in October of last year, and my partner that time was Morgan from the USGS office. But this time, she was offered a chance to go to a conference in Japan, so Nicholas was my partner for the tour. We also had a special guest along this time. Back in April, Kathleen and I had gone on the Nastie Nellie Oleson Tour with Alison Arngrim in Hollywood. This was tremendously entertaining, and along the way, I told Alison about the earthquake tour. She was interested, but the tour was already sold out. But it turned out that Sandi had held one seat in reserve in case Nicholas or I wanted to bring a guest, so Alison got the guest seat for the tour.

After a quick tour of the Seismo Lab, we headed up to the fault scarp at the McDonald’s in San Fernando. I also went inside to get some iced tea and to use the bathroom. That was where I saw what I can only assume is an unfortunate typo on the soap dispenser.

In Palmdale, we took in the view from the overlook by the freeway, and then climbed up the little hill so we could look down into the famous road cut where the 14 freeway crosses the fault. Then it was time for our lunch stop at Charlie Brown Farms. After that, it was time for Pallett Creek. We knew that the mysterious signs that marked where the fault crosses the road had been recently vandalized after more than a decade of marking the spot. So I’d made a new sign, which we brought along to use for the photo-op, even if it’s not properly planted in the ground. Then we traveled the quarter-mile or so to the actual trench site next to Pallett Creek. It’s not much to see, but it’s a chance to talk about how Kerry Sieh invented the science of paleoseismology there, back in the 1970s.

Heading up into the mountains, we stopped at the road cut near Big Pines to dig in the fault gouge. Then a quick bathroom stop in Wrightwood before heading down the other side of the mountain into Cajon Pass. There, we got to see Lost Lake, a small sag pond on the fault there. I like Lost Lake just because it looks like such an improbable thing. A pond all by itself, surrounded by desert. We also were very lucky this time. To get to the lake, we have to cross four railroad tracks. On the way in, we saw a train that had just finished passing the crossing when we got there. And while we were at Lost Lake, I saw another train come by. But that one finished passing by just as we were leaving. Cajon Pass is one of the toughest stretches of railroad in the U.S., and the trains there tend to be very long, and very slow-moving, so we were lucky to have missed both of them this time.

P-22 Day

Filed under: — stan @ 5:01 pm

This morning, when we were riding through Griffith Park, I saw a sign for the P-22 Day Festival. This was in honor of P-22, the famous Griffith Park puma. So after I got home, Kathleen and I went back to the park to go see it.

There were booths with exhibits about wildlife conservation, and mountain lions in particular. About plans to build a wildlife overpass over the 101 freeway, since crossing freeways is one of the most dangerous things that wild animals have to do. The had a stuffed puma that had been killed by poachers so we could see what it looked like up close.

It was an odd little event, but fun in its own way.

San Andreas Fault with Atlas Obscura

Filed under: — stan @ 7:51 pm

Today was yet another edition of the Atlas Obscura San Andreas Fault Scavenger Hunt. This is the third time I’ve been doing this tour with Atlas Obscura, and it seems to be as popular as ever. This time, my partner for leading the tour was my friend Morgan from the office.

We all met at the Seismo Lab, and we started off with a quick tour of the lab. We saw the lobby exhibits about the history of earthquake study, the media center upstairs, and a small exhibit about Charles Richter and Beno Gutenberg, who started the Seismo Lab and systematic study of earthquakes back in the 1930s.

The first stop of the tour was the small fault scarp next to the McDonald’s drive-through in San Fernando. This is a small remnant from the 1971 Sylmar earthquake.

The next stop was the scenic overlook and the famous road cut along the fault in Palmdale. When we were walking up the hill to look at the road cut, we ran across a tour group of students from Long Beach State. They were apparently doing about the same tour as we were, but traveling in the opposite direction.

We stopped for lunch at Charlie Brown Farms, which is still a deeply weird place. This time, I noticed that they had camel meat in the freezer. I suppose it tastes like chicken…

After lunch, we had a pair of stops close together. One at the signs marking the fault, and then at the Pallet Creek trench site, which was where the science of paleoseismology was born. The signs are kind of a silly stop, but it’s a chance for a photo-op. The trench site is interesting from the standpoint of it being important to the history of science.

Now it was time to go into the mountains. We stopped at the road cut that has the fault gouge on one side, and we showed everyone how the rocks in the sand could be crushed by hand. That’s always popular. Then we continued on to Wrightwood.

The last stop was at Lost Lake in Cajon Pass. Last year, it was suffering from three years of drought, and the lake had no water in it. But this time, it had some water, and was actually a lake.

And that was our tour.

So then this happened…

Filed under: — stan @ 9:53 pm

On Saturday the 23rd, we moved Lucinda into her new room at Porter College at UC Santa Cruz. This was exciting and sad at the same time for all of us. But the sad will pass and the exciting will take over. So here we go…

The Main Event

Filed under: — stan @ 8:03 pm

So, after two volcanoes, some sloths, thousands of tiny salmon, and dinner with Aunt Karen, it was finally time for the real reason for the whole trip. The total eclipse, and we had good front-row seats in the back yard of Kathleen’s brother Johnny’s house in Salem, Oregon.

We got stupendously lucky with the weather. It was a perfect, clear blue sky when we woke up. I set up my telescope with the camera on a little portable workbench on the back patio. With the clock drive going, the telescope tracked the sun as it rose.

I snapped a few pictures of the sun through the solar filter just to see what it looked like, and to get the camera settings right. I’d used the filter before for the transit of Venus, and also a partial eclipse in 2012. But since I’d never seen a total eclipse before, I knew that I’d be guessing about the settings when that time came.

First contact was about 9:00AM or so, and it looked just like every other partial eclipse I’ve seen over the years. We just watched as the Moon slowly marched across the face of the Sun. It wasn’t until it was probably 90% covered that we could really notice that the light was getting dim, and right at the end, it got cold, too. But then, when the actual moment of totality came, it was like a switch was flipped, and I suddenly realized just why people travel all over the world to chase eclipses. It was really quite spectacular.

I pulled the filter off the telescope, and took some photos. I’d set the camera for ISO 800, and started with a guess of about 1/60 second exposure. Then I increased the exposure on each shot, just to see what it would look like. Because I’d forgotten the remote shutter-release thingy at home, I had to set the camera on a 2-second timer. That way, for each picture, I’d press the button by hand, and then the telescope and camera had two seconds to stop wiggling before the shutter tripped. For a last-minute workaround, it worked reasonably well. And besides, the enforced wait between pictures gave me some time to just look up a the sky, slack-jawed at the sight of the solar corona.

As the Sun started to reappear, I snapped a couple more pictures, and by sheer luck, I got a reasonably good picture of the ‘Diamond ring’ effect right at the end of totality. All told, it was a good time, and was easily the thing that made the whole trip worthwhile.

Lava River Cave

Filed under: — stan @ 5:25 pm

Today was our last day at Newberry Volcano, and we got up early to go and see Lava River Cave before it was time to head back to Salem for the eclipse.

The cave opens at 9, and we got there a bit before that, just so we could be in the first group to go tour the cave. The rangers gave a short talk about cave safety, and then we picked up our rental lights and headed down to the entrance. Even though it’s August, the inside of the cave was an even 42 degrees, so it was actually pretty chilly.

The cave itself was pretty big. Most of it was just easy walking. There were just a few places where the roof was low, and we had to stoop a bit. The floor of the cave was covered in sand. The rangers said that the sand was actually ash from the eruption of Mt Mazama, about 7,000 years ago. That eruption left a thick layer of ash over the whole of what is now central Oregon, and the ash was washed down into the cave by rain over the years.

The walk through the cave was about a mile to get to the end. The cave went on, but the ceiling was very low, and the sign said to turn around and go back. So that was our little cave adventure, and now it was time to head back to Salem to see the eclipse.

Newberry Caldera and Lava Butte

Filed under: — stan @ 8:52 pm

Today was our day to play tourist in the caldera at Newberry Volcano. We were staying in a little bed-and-breakfast place, and while we were having our breakfast, we saw couple of bucks wandering by. Then we headed over to the volcano. The first stop was at Paulina Falls. This is the western edge of the caldera, and it’s where water from Paulina Lake drains out of the crater. From there, we went to the visitor center. They had a stack of the USGS fact sheets about the volcano. I told the guys there that it was that fact sheet that got me interested to come there and see it.

Our next stop was the Big Obsidian Flow. This is one of the newest lava flows, at only about 1,300 years old. Apparently, obsidian was an ideal material for making arrowheads and other cutting tools in the ancient world. And it’s usually hard to come by. But this lava flow had lots of it. So the people who lived around here were able to collect it and trade it for other things. The signs along the trail said that arrowheads made from Newberry obsidian are found all over the western U.S.

After the obsidian trail, we went to the East Lake Resort for lunch. We also walked along the shore of the lake a bit, looking for hot springs. Apparently, the two lakes are both fed by hot springs that just sort of seep out of the lake shores.

The next stop was Lava River Cave. This is another lava tube cave. It’s open during the day, and the rangers there rent out lights to use in the cave. But when we got there, there were too many people already there, and we couldn’t get in. So instead, we went on the main visitor center at Lava Butte.

Lava Butte is a small cinder cone volcano. It formed in an eruption about 7,000 years ago. It’s also surrounded by a large lava flow that came out at around the same time. We took the short trail through the lower part of the lava flow. After that, we rode the shuttle bus up to the top of the cone. There, we walked the short trail that goes around the rim of the crater. By this time, the wind had shifted a bit, and the air wasn’t as smokey as this morning. Since we missed seeing the cave, we made plans to come back first thing in the morning to see it before heading back to Salem.

Salmon and sloths

Filed under: — stan @ 9:30 pm

Today was an odd day. It was mostly traveling from Mt St Helens down to central Oregon to see Newberry Volcano. And along the way, we went to see a salmon hatchery on the Lewis River, also a sloth rescue, and we met up with my aunt Karen for dinner.

We started off at the salmon hatchery. One of the guys who worked there gave us a short tour of the facility. He said that the salmon would be returning starting in a couple weeks. At that point, the fish get diverted into the tanks there, and then they are sent into the sorting room. Wild fish are separated out and put in tanks to be taken up river in trucks. The hatchery fish are taken and ‘artificially spawned’ to create the next generation, and the fully-grown fish end up being given to food banks.

Our next stop was the sloth center in Ranier, Oregon. They took us on a short tour, and then we got to have a close-up meet-and-greet with some of the sloths. They gave us a little bowl of cucumber wedges to feed to the sloths. And they said that we could pet the sloths while they were (slowly) chewing on the cucumbers.

We had to pass through Portland, so we met up with my aunt Karen for dinner there. This was the first time I’d seen her since 1994.

The last part of the journey was up and over the mountains between Salem and Bend. We saw some nice lenticular clouds over Mt Jefferson there. After that, we descended down the eastern side of the mountains, and into a tremendous cloud of smoke from some big forest fires that were going on there. The city of Bend was completely enclosed by the smoke. We were going to be staying a bit south of there, right outside the Newberry National Volcanic Monument. I’d run across a USGS fact sheet about this volcano at my office, and it sounded like an interesting place.
