One Tam: many ways to give back to the mountain that gives us so much

A Glimpse into the Secret Lives of Mt. Tam

In the Lab

For those who enjoy viewing wildlife photos, this is your chance to spot a mountain lion, baby coyote, or family of foxes! Our cameras collect hundreds of thousands of images, and each one needs to be checked by human eyes. Twice a month, volunteers can come learn to identify the mammals captured on camera and enter the images into our database. In 2015, our volunteers cataloged over 200,000 photos!
