Gravely Mountain anchors the southern portion of this landscape, where mining operations were once active during the late twentieth century. Economic activity in this corner of the state is evidenced by the Gravely Mine and Gimlet Mine, located along the slopes above Gimlet Creek. The terrain is defined by the broad Avon Valley to the east and a series of drainage systems, including Strickland Creek and Finn Creek, which carve through the high country. Small-scale ranching or livestock infrastructure is noted by a Corral near Halfway Creek, illustrating the land's utility for both mineral extraction and grazing. The presence of several 4wd tracks suggests a period of transition where traditional resource extraction routes remained the primary means of navigating this part of Powell County.
