Unit 388

Mount Helena and Scratchgravel Hills provide prominent visual references for navigation and orientation. Hauser Lake forms a clear eastern boundary and water source, while Helena Valley Regulating Reservoir offers another distinguishing feature. Major drainages including Last Chance Gulch, Prickly Pear Creek, and several smaller creeks run north-south through the valleys, creating natural travel corridors and seasonal water.

These gulches break up what is otherwise relatively open country, offering natural hunting routes and areas to focus effort away from roadsides.

Terrain ranges from approximately 3,600 feet in the valley bottoms to just under 5,700 feet on the ridges and foothills—modest elevation change across mostly open country. The landscape is dominated by sagebrush flats, grasslands, and dry hillsides with scattered juniper and ponderosa pine on the higher slopes. Vegetation is sparse enough to allow extensive glassing, though scattered timber and gulch systems provide travel corridors and cover.

The lower elevations support pronghorn habitat, while the gentle ridgelines and foot-hills transition to denser forest approaching the national forest boundary.

Over 1,200 miles of road network provides extensive connectivity throughout the unit—among the highest road densities in Montana. Interstate 15 forms the northern corridor, while US Highway 12-287 and State Highway 279 offer major access routes. County and local roads penetrate most of the unit, making nearly all country reachable by vehicle.

This accessibility translates to significant hunter pressure, especially on weekends and during opening weeks. Success often depends on hunting early mornings, weekdays, or moving into rougher terrain away from main roads where fewer hunters venture.

Unit 388 encompasses the foothill valleys and open country immediately surrounding Helena, spanning portions of Lewis and Clark and Jefferson Counties. The unit's northern boundary runs along Interstate 15 north of Helena, while the southern edge follows the national forest boundary near Scratchgravel. Eastern boundaries trace Hauser Lake and its shoreline, while the western edge runs along the Helena National Forest perimeter.

The entire unit sits within 20 miles of Helena, making it one of Montana's most accessible hunting areas and one with heavy residential and recreational pressure.

Hauser Lake is the primary reliable water source along the eastern edge, with Helena Valley Regulating Reservoir providing another reservoir option. Seasonal streams including Prickly Pear Creek, Last Chance Gulch, McClellan Creek, and several smaller drainages flow through the unit but aren't consistently reliable year-round. Guillot Springs and scattered seasonal springs offer supplemental water.

During early and late season, reliable water becomes critical for locating animals; summer conditions may concentrate game near Hauser Lake or the larger drainages.

Unit 388 is pronghorn country, with the open sagebrush and grassland habitat providing ideal terrain for the species. Early season offers the best window before hunting pressure peaks. Hunt from ridges and hilltops to glass the open country systematically—the sparse vegetation allows long-range visibility.

Focus on draws and gentle valleys where sagebrush is thickest and where animals find cover. Pressure is heaviest within two miles of main roads and public access points; moving further into private land (with permission) or the rougher gulch systems provides better odds. Water sources, especially the larger drainages and Hauser Lake vicinity, concentrate animals during hotter periods.
