1959 Map of Yakutat C-3

About this map

Hidden Glacier and the massive Yakutat Glacier dominate this mid-century topographic study of the coastal mountain wilderness. This landscape is defined by the slow movement of ice and the erosion of sharp peaks like Slate Peak and the curiously named Black Tit. Within the Tongass National Forest, the map records an intricate network of drainage, where meltwater from the Moser Glacier feeds into Moser Creek and the Miller Glacier gives rise to Miller Creek. The presence of the National Forest Boundary (Indefinite) through the glacial valleys of West Nunatak Glacier reflects the difficulty of surveying this remote terrain during the era of aerial photogrammetry. Geologists and naturalists can observe the precise 1959 contours of Crescent Mountain and the Fourth Glacier before subsequent decades of glacial retreat altered the topography.
