Unit 24B

The Arrigetch Peaks provide iconic reference points for navigation and glassing in the central unit. Major drainages—the Alatna, Weyahok, and Pingo rivers—serve as natural travel corridors and reliable water sources. The Gates of the Arctic marks a critical gap at the range crest.

Anaktuvuk Pass and Survey Pass offer cross-range routes, though seasonally limited. Kanuti Flats anchor the western lowlands. The Endicott and Jack White mountains frame major valleys.

These features matter less as summits to climb and more as fixed navigation references in country where visibility can be limited by weather.

Most country sits below 5,000 feet, with rolling plains and low mountains dominating. Scattered boreal forest—primarily white spruce—dots the landscape in patches, typically concentrated along river valleys and south-facing slopes. Above the trees, alpine tundra with low shrubs, willows, and graminoids covers exposed ridges.

The median elevation around 1,700 feet captures the essence of this landscape: rolling rather than mountainous, but with enough relief to create distinct habitats. Permafrost underlies everything, controlling drainage patterns and vegetation type.

With only 115 miles of roads across 13,500 square miles—a density of 0.01 mi/sq mi—this is effectively roadless. Access depends entirely on aircraft (floatplanes to lakes and bars, wheelplanes to gravel strips) or boats navigating river systems. Staging areas like Bettles and Allakaket provide air service but come at substantial cost.

This extreme isolation naturally limits hunting pressure; only committed and well-funded hunters penetrate deep into the unit. Early season weather, caribou migration timing, and outfitter availability dictate pressure distribution more than terrain access.

Unit 24B encompasses 13,500 square miles of remote interior Alaska, straddling the transition zone between Arctic lowlands and the Brooks Range. The unit contains multiple river drainages flowing north and south, with scattered villages like Allakaket, Bettles, and Alatna serving as jumping-off points. This is deep backcountry—far from roads and civilization.

Ninety-one percent public land ensures legal access across most of the unit, but isolation is the defining characteristic. Geographic orientation is crucial here; the terrain blocks easy travel and obscures positions.

Water is abundant and essential for navigation and survival in this unit. Major river systems—the Alatna, Weyahok, Pingo, and Ram rivers—define travel corridors and offer float options for access. Countless smaller creeks and streams provide reliable water sources, though seasonal freeze-thaw patterns matter significantly.

Several documented springs exist but are sparse enough that modern hunting typically relies on flowing water. River valleys concentrate travel and wildlife use; in contrast, upland ridges can be dry. Flooding is possible during warm periods; river levels fluctuate with precipitation and temperature.

Unit 24B holds caribou, moose, Dall sheep, grizzly bears, and smaller game across diverse habitats. Caribou are primary quarry, with migration-dependent success in August through September as herds move between summer and winter ranges; understanding current herd location is everything. Moose concentrate in willows of major river valleys and tundra ponds—September rut hunting focuses on calls along drainages.

Dall sheep inhabit alpine terrain, particularly the Arrigetch Peaks and surrounding ridges; spotting-and-stalking from high camps is standard. Grizzlies are encountered throughout. Hunting success demands multi-week expeditions with air support, established camps, and intimate knowledge of current animal movement patterns—this is not a casual hunt.
