Friends of the COSA is a volunteer stewardship group that helps to take care of the COSA! Our August event will involve clearing vegetation to create trails in the COSA. Please wear sturdy shoes, long sleeves, pants and sun protection. Please bring a water bottle. We will provide snacks!

Park at the Inyo National Forest Supervisor’s Office lot at 351 Pacu Ln #200, Bishop (behind the DMV on West Line Street).

If you are a Tribal member you can earn a free dump run by participating in Friends of the COSA events. More information on the dump run incentive can be found here.

If you have any questions please call or text (760) 920-5525. Hope to see you there!
