Before the deluge

Today’s bike ride was up to Sunland to see a house that was mentioned in a talk I heard at Caltech about debris flows in the San Gabriel Mountains. Debris flows tend to follow major fires, and the Station Fire this summer certainly qualified. The scientist giving the talk said that this particular house had been destroyed in 1978, and then it was rebuilt in the same spot. They expect that the chance of it being destroyed this winter is close to 100%. So I thought this might make for an interesting outing for the bike club.
We rode out across Eagle Rock, Glendale, and Burbank, and then turned north into Shadow Hills. Along the way, we saw horses, and also a sculpture garden. Then we came out on Sunland Blvd and headed north. To see the house, we had to take a small detour into the mouth of Big Tujunga Canyon. The house sits in a small canyon just west of the main wash. There are two canyons that merge just above it, and it’s in a narrow portion of the lower canyon. So it’s easy to see how debris flows could come down and be concentrated right where the house sits. I suspect that the owners know this. In the picture of the house, it looks like they’ve installed some steel girders sticking up out of the driveway. They may be planning on putting up a deflection wall to try to guide the muck around the house. It will be interesting to see if that works.
Coming back, we stopped at Goldstein’s Bagels and then headed home. It was a nice ride.
44 miles.
