Not many cities in the world have a real mountain within the city limits. Cowles Mountain in San Diego is a prominent feature in our landscape. I can see it from the condinimum community where I live; and from Ed’s back yard in El Cajon this afternoon, looking west, the mountain rose impressively behind Grossmont College. It’s only 1600 feet high, but we count it as a mountain. The hike from the parking lot on the west side is 1.5 miles long.
I debated whether or not to include the geologic history of the mountain and decided to do it simply because I like knowing it and sharing it. The mountain consists of Jurassic and early Cretaceous metavolcanic and exposed shallow intrusive igneous rocks. These big rocks are a significant feature, especially on the west side. They hint at the kind of terrain found on the mountains higher up between El Cajon and Ramona. I love the really big rocks up there that look as if they were thrown by giants in a big battle.
