Yellow on red
Extravagant bloom of brittlebush on a steep slope of Hakatai Shale, Grand Canyon. On the slope above and upstream of Hance Rapids. A huge dark vein (basalt?) intrudes at upper left, and a much thinner one of white rock (quartz?) in middle. These features are more evident in other photos in GC album. The massive cliffs at upper right are the much harder Shinumo Quartzite formation.
