About this map

Labyrinth Mountain and the high alpine ridges of the Cascades dominate this 2017 survey at the intersection of King, Chelan, and Snohomish counties. The landscape is defined by its engineering history and recreational paths, most notably the subterranean path of the Cascade Tunnel and its predecessor, the Old Cascade Tunnel. These landmarks reflect the difficult passage through the mountains that once challenged the Great Northern Railway.

High-altitude lakes like Minotaur Lake, Lake Valhalla, and Lake Janus are tucked into the basins between Mt McCausland and Lichtenberg Mtn. The Pacific Crest National Scenic Trail winds through the center of the sheet, crossing Union Gap and passing near the headwaters of Smith Brook and the Rapid River. The inclusion of the Bygone Byways route along Nason Cr further highlights the area's transition from a critical transportation corridor to a protected wilderness within the Snoqualmie National Forest and Wenatchee National Forest.
