Unit 16A

Peters Creek serves as the primary navigation corridor through the unit's heart, draining from glaciated highlands into the Susitna River system. Mount Stevens and the Kashwitna Knobs provide dominant landscape references visible across wide areas. The Peters Hills and Little Peters Hills form the eastern spine of the unit, offering elevated vantage points for glassing open country.

Kahiltna Glacier and Kanikula Glacier mark drainage origins and create distinctive white features visible for navigation. Hansen Bar and Gilson Bar mark significant river features along braided lowland channels. Numerous named creeks—Whistler, Stony, Bear, Pickle, Rambler, Prospect—define drainage systems useful for travel and locating concentrations of game.

These landmarks anchor navigation in a landscape where many valleys appear identical from ground level.

The landscape is overwhelmingly low-elevation terrain, with 95 percent below 5,000 feet, creating expansive tundra and open country across much of the unit. Spruce and willow forests dominate lower valleys and drainages, providing critical shelter and forage. Transition zones climb into alpine meadows and tundra as elevation increases toward the Peters Hills and surrounding ridges.

Above 5,000 feet, vegetation thins dramatically into exposed rock, sparse grasses, and lichen-covered slopes. Glaciers cling to upper valleys, particularly around Kahiltna Glacier and Kanikula Glacier. This elevation profile creates distinct habitat zones—river valleys support dense riparian cover, mid-slopes transition into open foothills, and high country becomes pure alpine tundra accessible only in brief summer windows.

Extreme remoteness defines the access pattern here. Only 0.16 miles of road per square mile means virtually no road-accessible hunting. The nearest road access is at Petersville to the south, and even that connection is marginal.

Float planes represent the primary access method, requiring charter flights and associated cost. Established cabins exist near historical communities and along Peters Creek, but these are scattered points in vast country. The combination of distance, weather-dependent flying conditions, and the need for water-based travel strongly limits hunter numbers.

Most hunting pressure concentrates near float-plane landing zones on major lakes and river bars. Significant areas remain lightly hunted simply due to the effort required to access them. Hunters expecting to encounter crowds here would be mistaken—this unit's challenge is reaching it, not finding space.

Unit 16A occupies the western foothills and valleys of the Alaska Range, centered around the Peters Creek drainage and Kahiltna Glacier system. The unit spans from the flat river basins near Petersville north and east into increasingly mountainous terrain. Surrounding highlands include the Peters Hills and Dutch Hills, which form natural ridges defining drainage systems.

Nearly 97 percent public land dominates the unit, with minimal private holdings near historical communities. The terrain's extreme complexity stems from its vast size combined with geographic remoteness—no highway access exists, and scattered cabins represent the only human infrastructure. This is true frontier country where distance and weather are the primary constraints.

Water abundance defines this unit's character and hunting logistics. The Peters Creek system, Kahiltna Glacier outflow, and countless tributary streams create a braided network of navigable corridors suitable for small boats and float planes. Lakes scattered throughout lowlands—including Daltełi, Trapper, Home, Shulin, Jake, Scotty, Kroto, and Schneider Lakes—provide reliable water sources and landing zones.

Wallys Slough and similar features mark slower-water braids useful for travel. Seasonal flooding in spring and early summer can make some lowland areas difficult to traverse, but water scarcity is never a concern. The combination of glacial melt, spring discharge, and wetland systems creates persistent water throughout the year, though water quality varies from clear glacial streams to sediment-laden braids.

Unit 16A supports moose, caribou, Dall sheep, mountain goats, brown and black bears, and deer—species reflecting the diversity of lowland river valleys to alpine ridges. Moose concentrate in willow-choked drainages, particularly Peters Creek and tributary valleys where riparian browse is abundant. Caribou use open ridges and high tundra, with early season opportunities in September around alpine passes and ridge systems.

Dall sheep inhabit steep terrain along the Peters Hills and higher ridges, requiring mountain travel and glassing from distance. Mountain goats occupy cliff systems and lichen-rich alpine terrain. Bears hunt salmon streams during summer runs and berry patches in fall.

Success requires understanding seasonal movements tied to elevation—late summer finds game at higher elevations, while early season and rut often push animals into lower valleys. Plan logistics carefully: float-plane access, understanding weather windows, and accepting that several days may pass between sightings in this expansive terrain.
