Activitiesrock hounding in Mammoth


Rock Hounding in Mammoth It's a passion for some and a hobby for others, and the Eastern Sierra can fill any rock hounds sample books with a ton. There are over 200 different rocks and minerals listed for Inyo County in the California Mineral book published by the State of California. Some areas are private land and thus you need their permission before you can pocket a few samples. Protected areas are marked, so please don't remove pieces of nature if you are asked not to.

Mammoth is made up of craters, volcanoes, obsidian glass, lava and a lot of granite. Here are some places where you can see and uncover some good sites and perhaps samples for your collections.
