Black Knoll




Plate 525X. Black Knoll 1931 – 2004 Viewed west-northwest across the Sink and Kanab Creeks to Black Knoll (6,760 ft.). The foreground has been root-plowed and reseeded with crested wheatgrass to improve range conditions. Despite that treatment, rubber rabbitbrush has increased and sagebrush has begun to reinvade the site. Pinyon, juniper, and oakbrush have increased except where they have been chained, pushed, or cut.
