Southern California has many faults, some hidden, some very obvious. One of the more fun aspects of geology is to see where the land moves. To witness the power of what Earth can do can be quite awe inspiring. Some features are easily recognizable, such as the San Gabriel Mountains which have somewhat rapidly risen …
On July 6, 2021 at 6 pm, I will be giving a presentation for the Historic Highway 99 Association of California on the history of US 99 through the San Gorgonio Pass. The route will be covered from Thousand Palms to Calimesa. Photos of the route, new and old, as well as maps showing the various alignments will be shown. Come join us!

Near Valyermo, California, outside of Palmdale, the locals have placed signs where Pallet Creek Road crosses the San Andreas Fault. They picked a really nice spot too, as you have a sag area, fault scarp, and offset streams all easily visible from there. I recommend a visit!
After taking a small poll on this site regarding possible highway tours, the results are in. It would seem that the Cajon Pass area was the most popular. As such, it will be the first tour given. Unless conditions warrant otherwise, the first tour will be on August 12, 2017. It will begin at the San Bernardino Metrolink station at 10 am. While a more exact itinerary will be created in the near future, the tour will cover the highway as well as the geology from the train station to Cajon Summit. The tour will be in a caravan style with specific stopping points. There may be some short hikes as well to see old pavement, alignments, or bridges. There will also be no cost for the tour. Please RSVP as soon as you can so I can get an idea of how many may show. It should be a lot of fun and I hope to see you out there!
Lately, there has been quite a bit of press about the recent “San Andreas” movie.

Some basic stereotypes exist in the movie, many of which are completely false. Starting with the magnitude of the earthquake …
