About this map

Missouri River geography dominates this 1962 field-checked study of the Gates of the Mountains area, where the water transitions through Upper Holter Lake toward the reservoir at Hauser Lake. The map details a landscape of deep canyons and named gulches, anchored by Hauser Dam and its associated powerplant. Genealogists and local historians can locate early settlement traces like the Hilger Ranch and the interestingly named Old Wells and French Place situated along the western valley slopes.

The rugged terrain of the Helena National Forest includes prominent peaks like Sacajawea Mountain and specialized riverfront features such as American Bar and the Meriwether Picnic Area. Numerous narrow drainages, including Cochran Gulch, Fields Gulch, and Towhead Gulch, carve through the heights, illustrating the complex drainage patterns that feed into the river system during the mid-20th century.
