Trinity Alps and its surrounding high-elevation landscape are defined by a network of creeks and steep gulches in this 2012 study of Trinity County. The terrain is marked by significant peaks such as Monument Peak and Weaver Bally, while the hydrology is anchored by the Rush Creek Lakes and East Fork Lakes. Evidence of historic water management or mining activity appears in labels like Sweepstake Ditch, which traverses the slopes near Schofield Gulch.
