The most common shrubs here are brittlebush (Encelia farinosa) and jojoba (Simmondsia chinensis). Other conspicuous plants seen are saguaros (Carnegia gigantea), foothill paloverde (Parkinsonia microphylla) and a large organ pipe cactus (Stenocereus thurberi) right at the trailhead.

Trail splits. Left is Estes Canyon Trail and right is Bull Pasture Trail.
Waypoint 3: (N32.01695 W112.70855)
At this point the trail crosses another small wash. It is here where we start seeing Samo Prieto or baby bonnets (Coursetia glandulosa) along the trail. This is a fairly large shrub seen in scattered locations in the Monument but apparently not elsewhere this far west. It displays attractive yellow and pink pea-shaped flowers in March. Samo Prieto (Coursetia glandulosa) will be seen scattered along the trail almost to the overlook. Also desert agave (Agave deserti) will be occasionally seen scattered along the trail.
