On the creek banks grow a gallery woodland, of varying continuity, standing in stark contrast to the surroundings. Narrow-leafed and Fremont Cottonwoods are the dominant trees, both numerical- ly and in size. The largest trees were Fremont Cottonwoods, but large individuals of both species exceeded 60' and 40" dbh.

These trees overtopped a mixed, irregularly scattered understory of Virginia Creeper, squash vine and many other forbs and grasses I cannot name. Along the edge of the stream channel in several places grew small narrow-leaved & Fremont Cottonwoods, crooked willows and some patches of grass. Spring-fed tributaries to the creek at a couple points had heavy growths of mixed
