Description:
A tour of a tailings (mine waste) pile near Randsburg in far eastern Kern County, California in the Mojave Desert, generates a discussion of drainage development on the anthropogenic landform. Drainage is centripetal toward a circular depression occupying the center of the waste pile, and it includes both surface rills and underground piping features, the outlets for which are located along the perimeter of the depression. Sediments moved through the pipes include gravels composed of granitic and metamorphic (schist?) clasts, the color of which contrasts markedly with the light yellowish tan color of the mine waste. Small-scale alluvial fans composed of these gravels have formed at the outlet to some of the pipes around the perimeter of the central depression or pit. The mouth of each pipe outlet channel forms the locus of each fan apice. TECHNICAL: Equipment | video function on a hand held Canon PowerShot A630. Editing | Windows Movie Maker
