Unit 330

The Centennial Divide dominates the landscape as a major north-south ridge system offering orientation and glassing opportunities. The Gravelly Range and Ruby Range bracket the unit's eastern and western flanks—key reference points for navigation. Specific basins—Fossil, Antelope, Wolverine, and Elk River basins—provide logical hunting compartments within the larger unit.

Named springs including Kelly Spring, Virginia Springs, and Warm Springs mark reliable water sources. The Narrows channel and Hoodoo Pass, Snowshoe Pass, and Raynolds Pass are notable terrain features that funnel game and provide staging points for exploration.

The unit transitions from sagebrush-dominated valley floors near Twin Bridges and Ennis through rolling foothill country into significant high-country basin systems. Upper elevations feature exposed ridgelines, scattered subalpine timber, and parkland meadows typical of Montana's intermountain basins. Mid-elevation slopes support mixed conifer forest with reasonable density, while lower country and valley margins transition to grassland and sagebrush.

The Centennial Divide forms a significant spine across the unit, creating distinct drainage basins and habitat zones. Elevation gain is substantial enough to create meaningful seasonal migration corridors.

Fair vehicle access via 1,800 miles of road means the unit sees use but isn't heavily roaded. Key approach routes follow USFS 290, 324, and 347, connecting valley staging areas to higher country. The complexity of the terrain and fair-weather road conditions mean many hunters stick to accessible ridges and lower basins.

This creates opportunity for hunters willing to explore drainages thoroughly and camp at higher elevations. Summer and early fall generally offer the best access; late-season hunters may face road conditions limiting vehicle approach to mid-elevations.

Unit 330 encompasses the country between Twin Bridges and Ennis to the north, with Dillon anchoring the southern boundary. The unit is bookended by State Highways 41 and 287, making it accessible from several staging towns. Internally, the Centennial Divide, Long Creek Road, and USFS routes define key travel corridors.

The terrain spans the upper Madison Valley drainage system and transitions from valley floor elevation near 5,000 feet up to high-country basins above 10,000 feet. This is substantial country—big enough to absorb pressure and reward thorough exploration.

Water availability is limited relative to unit size, requiring strategic planning. Major creeks—Trout Creek, Big Dry Creek, Ledford Creek—flow through key drainages and provide reliable water corridors. Named springs are scattered throughout, particularly in basin areas and along ridge systems, but require prior research or local knowledge to locate reliably.

Ruby River and its associated reservoir offer consistent water in lower country. Higher elevations may have reliable water only seasonally. Successful hunting often hinges on locating springs and timing hunts around water availability in basin country.

Unit 330 holds moose in suitable habitat—the scattered timber, basin country, and presence of willows in drainage bottoms provide the structure moose prefer. Early season finds moose in higher basins and along willow-lined creeks; rut hunting targets drainage corridors where bulls move between basins. Key strategy involves glassing basin systems from ridges like the Centennial Divide, then stalking into timbered pockets and willow thickets.

Water sources become critical focal points—moose congregate near reliable springs and creeks. The unit's size and complexity reward methodical coverage; success often depends on patience working specific drainage systems rather than covering miles of country.
