About this map

Glacier Peak anchors this late-Victorian era survey, rising above a landscape defined by the intersection of Skagit, Snohomish, and Chelan counties. The map documents the high alpine reaches of the Cascade Range just as the Washington National Forest was being administered. To the southwest, the mining era's influence is evident near Monte Cristo and Barlow Pass, where the drainage of the South Fork and North Fork rivers begins.

Glacial hydrology dominates the eastern and northern portions, from the remote Horseshoe Basin near Sahale Mt. to the deep waters of Illabot Lake. The terrain is marked by numerous bench marks, such as B.M. 10436 on the summit of the central peak, reflecting the rigorous surveying work led by T.G. Gerdine and E.C. Barnard between 1897 and 1899. This survey captures the region before extensive modern trail networks, showing the primitive access routes through the Whitechuck River valley and toward Goat Lake.
