Cottonwood tree

Description:

Bark: Light green, smooth on young trunks; on older trunks thick, gray, deeply furrowed with flat-topped ridges

Habitat:

Native from about the Wasatch Front south including lower-elevation river drainages (Green and Colorado) in southern Utah and throughout the Southwest. Usually found naturally along streams.

Notes:

I am actually guessing at the species based on what I have read- had no idea there were so many varieties of Cottonwood
