Q: Why are the rocks in Chatsworth different from the rest of the landscape? It’s crazy.
A: Ten years ago the land near Stoney Point became a condo development; 100 years ago it was a movie ranch; 1,000 years ago it was a Tongva settlement; and 3,000,000 years ago it was beachside property. Sediment from the San Gabriels washed down an ancient river, congealed into sandstone at the Pacific, and was thrust up by earthquakes. Explore these geezer rocks during REI’s Sunday climbing classes.
