B.R. MOON 1987 Species Account Desert Tortoise (Gopherus agassizii) April Vulcan Mine Road approximately 5 miles from Kelbaker Road, Providence Mountains, San Bernardino co., CA. I found an adult tortoise active on the north side of Vulcan Mine Road late in the afternoon. Habitat was partly rocky, Creosote bush & Yucca vegetation on gently sloping bajada near the mountain ridge that extends furthest toward Kelbaker Road along Vulcan Mine Road. There was a burrow about 3 meters from the tortoise that looked about the right size for the tortoise to live in; the tortoise was headed in the direction of the burrow.
