Site is located in minor saddle of ridge between Rim Trail and first canyon on north side of reservoir (upstream of dam). Same ridge runs due south from "Anvil" rock formation. Both species of Arctostaphylos were combined to elevate the percentage to justify a Chamise - mixed Manzanita Alliance (otherwise, it becomes a Chamise Alliance, which does not reflect the stand / plot accurately). Plot is denser than releve #764, similar aspect and placement on the ridge. Stand continues downhill, almost to Rim Trail.
