Bullion Mine and the Ontario Millsite stand as central landmarks in this high-elevation mining landscape near the continental divide. The terrain is defined by a dense concentration of mineral claims and extraction sites, ranging from the Paupers Dream Mine to the Sure Thing Mine, many clustered around the drainages of Telegraph Creek and Ontario Creek. Small settlements and named camps such as Hub Camp, Bullion Parks, and Jimmy are situated among the peaks, providing rare points of habitation in the mountain geography. This area’s heavy industrial legacy is recorded in detail, showing how mines like the Beatrice Mine and Champion Mine are deeply integrated into the gulches and ridges that define the watershed. Between high points like Jericho Mountain and Old Baldy Mountain, a network of unimproved roads and trails connects these remote workings to the larger valleys below.
