Hoping to get a better shot, I circled the valley a few times, but never saw it again.
A side view of the black harvester anthill, showing its elevation.
A closer look at the harvester ants at the entrance to an anthill. Note the wide variety in sizes - for example, just left of the tunnel opening, a very small harvester ant crawls on top of another ant more than twice its size.
A perfect ring of litter surrounding a harvester anthill.
Desert sand verbena Abronia villosa
Leaves on the Dyeweed (Emory's indigo) bush Psorothamnus emoryi. The name 'dyeweed' comes from the persistent iodine color that stains your fingers if you damage a leaf.

This Orcutt's woody aster Xylorhiza orcuttii was pointed out as having unusually white petals.
Skeleton Weed Eriogonum deflexum var. deflexum
A much tougher rock, which showed very different color on its flat face than on its outer surface.
An extremely brittle rock, which could be easily broken into fragments by hand.
Vulcan Mountan's radio transmitter pokes up above mountains in the distance behind a near ridge of Coachwhip Canyon, lined with Ocotillo Fouquieria splendens ssp. splendens and other plants.

Aphids cluster around Rush Milkweed (Ajamete) Asclepias subulata flowers.
This milkweed is one of 3 possible origins for the name of the canyon, with its long curved stem said to look like a buggy coach's horse whip. The others are the coachwhip snake, and the ocotillo which once counted 'coachwhip' among its common names.

The latin-ish name "Psorothamnus" seems to refer to these scabies-like scales that cover the fruits on this species.
The surrounding burrs revealed by a close-up of the flowers on the Burro bush Ambrosia dumosa elucidates why it is also called "white burr sage".
Dyeweed (Emory indigo) bush Psorothamnus emoryi
A young Brittlebush Encelia farinosa, whose leaves have not yet acquired the fine hairs that give them their white color - not surprising, since that is a summer drought adaptation, and it is neither summer nor dry at the moment.
