Los Angeles County Survey Records

Los Angeles County Department of Public Works has a wealth of information available on their website. With a bit of patience and some looking around, you can find quite a few treasures using their mapping application. I’ve so far found the original survey data for the “Bridge To Nowhere” roadway, plans for other roadways that were never built in the Sierra Pelona Mountains, as well as the forest service permit for the Shoemaker Canyon Road that was never completed.

USGS Earthquake Swarms Information

There appears to be the beginnings of a small swarm of earthquakes in the Brawley Seismic Zone, this time in the town of Brawley, California. The USGS has a great website on swarms and why they occur.
