About this map

Charter Oak Mines and a dense concentration of hard-rock workings define this high-elevation landscape of the Helena National Forest. The drainage network of the Little Blackfoot River and its tributaries, including Monarch Creek and Ontario Creek, provided the necessary water for early 21st-century mining operations. The map reveals a complex history of extraction, featuring specialized sites like the Monarch Mill Site and several named claims such as the Orphan Widow Mine and Golden Anchor Mine.

Relief is dominated by the prominence of Bison Mountain and Treasure Mountain, with more isolated landmarks like Irish Mine Hill and Baldy Ridge providing navigational points for prospectors and foresters. The area around Blackfoot Meadows offers a rare break in the steep terrain, while the network of forest roads, including Ontario Creek Rd and Slate Creek Rd, facilitates access to these remote reaches of the Rocky Mountains.
