The Sheep Tanks are in a slot canyon in the north-eastern part of Anza Borrego Desert State Park, east of the Santa Rosa Mountains. The slot canyon has several deep water pockets (called tinajas), their capacity is estimated to be ~20,000 gallons (75,600l). It is an important watering hole for Bighorn Sheep (hence the name Sheep Tanks) and other wildlife.
I made some of these photos by holding the camera out over the edge of the slot canyon with either my arms, or by extending the tripod out vertically. It wasn’t exactly the most comfortable position and it made me quite uneasy being so close to the edge, but I’m quite happy with the results. :)
