Big Rock Wash Wildlife Sanctuary has 37 different species of annual wildflowers including Indian Rice Grass, Desert Calico, Checker Fiddleneck and abundant displays of Dune Primrose. Following a monsoonal thunderstorm in the late summer months, the wash can be full of water turning the sanctuary into an oasis, a respite from the summer heat. This virtually undisturbed area is comprised of a desert-wash community including creosote bush scrub and Joshua tree woodland and is one of the most diverse of the Antelope Valley sanctuaries in terms of plant life.
