1968 Map of Oss Peak

USGS Topo · Published 1987

About this map

Lake Chelan defines the southwestern corner of this survey, where the small landing at Dutch Harbor sits at the base of the steep Cascades. The map documents a complex system of hydraulic infrastructure, most notably the Siphon Grade and Aqueduct Road, which trace the contours of the mountains to manage water across the demanding terrain. These engineering features represent the mid-century efforts to harness the region's steep hydrology for local utility.
