1985 Map of Yakutat C-2

About this map

Tongass National Forest dominates this section of the Alsek River region, capturing a dramatic landscape of active glaciation and terminal geology along the international border. The survey delineates the massive Yakutat Glacier and Novatak Glacier, which converge and retreat, leaving behind extensive fields of Moraine that reveal the movement of the ice over time. This 1985 edition, based on 1958 photography, provides a look at the frozen boundary between British Columbia and Alaska, where the Canada-United States border cuts through the ice fields. Other significant ice bodies including East Glacier, Nunatak Glacier, and Battle Glacier fill the high-elevation valleys, illustrating the sheer scale of the coastal mountain range's ice system before modern glacial thinning accelerated.
