1975 Map of Chelan

Settlement patterns are concentrated in the fertile valleys and along the shores of Lake Chelan, where communities like Manson, Lakeside, and Sunnybank are clearly marked. The presence of Lake Wenatchee State Park and Lake Chelan State Park highlights the importance of the region's water bodies for recreation and conservation. This survey preserves the mid-century layout of small mountain towns such as Peshastin, Dryden, and Cashmere before late-century growth changed the character of the Wenatchee River corridor.
