2024 Map of Greenhorn Mountain

USGS Topo · Published 2024

About this map

Mullan Pass serves as a central anchor for this portion of the Helena National Forest, marking a historic crossing point over the Continental Divide. The high-elevation terrain is defined by a dense network of gulches and ridges, including Drumlummon Hill and Mt Belmont. Small settlements and named locations like Blossburg, Skyline, and Weed are concentrated along the southern corridor near the Austin Mullan Pass Rd. The map illustrates a landscape shaped by both early transportation routes and resource extraction, with features such as Thompson Flats and the Beaver Ponds near Meadow Creek providing water and level ground amidst the steep slopes of Greenhorn Mtn and Bald Butte. Access is provided through a web of Forest Service roads, including Snowshoe Deadwood Rd and Ottawa Gulch Rd, which navigate the complex drainage systems of Silver Creek and Dog Creek.
