1963 Map of Mc Gregor Mtn

About this map

The Stehekin River valley carves through this high-altitude landscape where the boundaries of the North Cascades National Park and the Lake Chelan National Recreation Area meet. In the early 1960s, this area remained a vital corridor for wilderness travel, anchored by the Pacific Crest Trail and the High Bridge Guard Station. The map illustrates a high-alpine environment defined by prominent peaks like McGregor Mtn and Mt Benzarino, along with the icy reaches of the Sandalee Glacier and Lyall Glacier. Settlement is restricted to seasonal outposts and recreational sites such as Dolly Varden Campground and High Bridge Campground. Notable geographic markers like Agnes Gorge and the Memaloose Ridge provide clear evidence of the complex hydrology and verticality of the Chelan backcountry during this era of conservation and forest management.
