Description Upheaval Bottom is a largely barren landscape in the 1960s. A thin line of tamarisk outlines a drainage, with some greasewood and other shrubs nearby. The sandy alluvial fan at the base of the cliffs in the background hosts a few four-wing saltbrush and bunchgrass.

Description Tamarisk is thickly filling the streambed across this view of Upheaval Bottom. A hiker in the center left shows the very large size of these trees. Greasewood, four-wing saltbush, and a few small weeds and native grasses cluster near the stream and thin out as the slopes rise.

Description Tamarisk are showing impacts of tamarisk beetle with dead crowns and sparse leaves. Declining tamarisk may have allowed the stream to make deep cuts into the streambed. Upland native bunchgrasses including galleta grass and Indian ricegrass are thriving on the rocky slopes and have taken over the sandy alluvial fan at the base of the cliffs.
