2001 Map of Upper Holter Lake

USGS Topo · Published 2004

About this map

Upper Holter Lake and the Missouri River corridor dominate this landscape within the Helena National Forest. The geography is defined by the narrow passage of the Gates of the Mountains, where the river carves through limestone cliffs. Local settlement history is represented by the Hilger Ranch and Hilger Well within the broad Hilger Valley, while the southern reaches of the map show the industrial infrastructure of the Hauser Dam and its associated Powerplant. Numerous named gulches and canyons, such as Meriwether Canyon and Sacajawea Mountain, reflect the historical Lewis and Clark expedition's journey through this terrain. The map also detail boat access points like the Gates of the Mountains Boat Club and several designated picnic areas along the water's edge.
