This plant is all over in the canyon these days and looks more like a ground cover than a wildflower. Flowers are yellow and rather inconspicuous. Leaves are 'furry'. One of its common names is Honeymat (Tidestomia lanuginosa); the other Woolly Tidestromia: think 'woolly tide'. Bonus bee fly (thanks, Fred, for this correction) in the photo above.
