Unit 06B

The Copper River is the unit's central organizing feature, providing both transportation and reference for navigation. Martin River enters from the east and creates a secondary drainage system with multiple sloughs (Mirror Slough, Martin River Slough). Miles Glacier and McPherson Glacier feed the Miles Lake system and major meltwater streams—these glacial features provide visual landmarks visible from considerable distance. Martin Islands, Long Island, and other named islands serve as navigation waypoints in the delta's complex island channels.

Lakes including Martin Lake, Miles Lake, and Lake Tokun anchor specific hunting zones. Summits like Goat Mountain and Mount Tom White, though modest in height, stand out in the low terrain and aid orientation. Multiple named channels (Long Island Channel, Flag Point Channel, Hotcake Channel) define water routes through the delta.

Over 94% of the unit sits below 5,000 feet, with median elevation around 700 feet and much of the terrain at or near sea level. The landscape transitions from open tundra and glacial outwash plains at the lowest elevations through sedge marshes and willow-alder scrub to scattered Sitka spruce pockets on slightly elevated ground. Glacial rivers deposit silt and gravel, creating constantly shifting channels and bars.

Higher slopes toward the eastern ridges support more dense spruce-hemlock forest, but these represent a small fraction of the unit. Vegetation is controlled by elevation, drainage, and tidal influence—wet, open country dominates, with forest confined to drainage margins and better-drained benches. The landscape is dynamic: channels migrate, sandbars appear and disappear, and seasonal flooding is routine.

This unit is extremely remote with minimal road infrastructure—only 38.5 miles of roads in over 1,000 square miles (0.04 density), making roads functionally irrelevant for hunting access. Access is almost entirely water-based: float planes to lakes or river landings, then jet boats up the Copper River and its drainages, or coastal boat access via the Gulf of Alaska. Staging from communities like Cordova (outside the unit) is standard.

The vast size and water-dependent access pattern mean pressure is minimal in most areas, but landing sites and popular lakes concentrate use. Winter access is limited due to weather and ice. The terrain's complexity and remoteness are significant barriers—this isn't day-trip country.

Only hunters equipped with boats, willingness to navigate tidal currents, and tolerance for weather delays and challenging conditions realistically access interior areas.

Unit 06B encompasses the Copper River Delta and surrounding lowlands in coastal southcentral Alaska—a sprawling landscape where glaciated mountains transition to tidal flats and river systems. The Copper River dominates the unit, carving through glacial valleys and feeding into a complex delta system of islands, sloughs, and braided channels. Major features include the Martin River drainage to the east and multiple named glaciers (Miles, McPherson, Johnson, Slide, Martin River) that feed meltwater into the lowlands.

The unit's southern boundary fronts the Gulf of Alaska; eastern slopes rise toward higher country but remain primarily low-elevation terrain. This is one of Alaska's most productive and dynamic river deltas, shaped entirely by glacial processes and tidal influence.

Water abundance defines this unit entirely. The Copper River is a major glacial system flowing north to south through the center; the Martin River enters from the east. Numerous sloughs (Chinaman Slough, Mirror Slough, Martin River Slough), seasonal channels, and creeks (Sheep Creek, Tokun Creek) crisscross the delta.

Lakes are scattered throughout: Martin Lake, Miles Lake, Little Martin Lake, Deadwood Lake, Lake Tokun, Lake Kahuntla, and Lost Lake provide freshwater and wildlife gathering points. Tidal influence is significant—lagoons like Softuk Lagoon see seasonal water level swings. Over 6% of the unit is water; most lowland areas experience seasonal flooding.

Water access is the primary consideration for hunting logistics; the Copper River provides the main transportation corridor. Glacier-fed systems mean milky, cold water; spring runoff dramatically alters terrain and accessibility.

Unit 06B supports diverse species across distinct habitat zones. Moose inhabit willow scrub along drainages and marsh margins—excellent hunting accessible via river approach during fall migration. Black and brown bears use river systems for salmon and berry forage; coastal and river corridors offer spring and fall opportunities.

Goats climb the modest eastern ridges; Goat Mountain and other slopes provide terrain hunts from base camps. Sitka blacktail deer concentrate in spruce pockets and alder-covered benches; early season glassing of elevation breaks works when accessible. Caribou and mountain sheep occupy higher ridges east of the main river.

Bison, if present, use open plains. The unit's remoteness and tidal/glacial dynamics mean success depends on understanding water access logistics, weather windows, and seasonal timing. Spring and fall offer best weather and species accessibility; summer brings warm conditions but challenging river navigation with runoff; winter is extreme.

Base camps near major lakes or protected sloughs are essential for multi-day hunts.
