About this map

Baird Glacier dominates this high-altitude landscape along the international boundary between Alaska and British Columbia. Surveyed in the early 1960s, the terrain is defined by massive ice fields and the deep crevasses of the Witches Cauldron. This portion of the Tongass National Forest showcases significant landmarks used for boundary demarcation, most notably the prominent Devils Thumb Boundary Peak 71 and the distinctive Cats Ears.
