1968 Map of Oss Peak

About this map

Lake Chelan anchors the southwestern corner of this survey, where the water meets the steep slopes of the Wenatchee National Forest. This 1968 field-checked record captures a landscape defined by dramatic elevation changes, from the lakeshore at Dutch Harbor up to the high points of Oss Peak and Fox Peak. The infrastructure of the era is evident in the Siphon Aqueduct and Grade Aqueduct winding along the lower contours, reflecting the region's management of water resources. To the north, the boundary with the Okanogan National Forest follows the heights of Sawtooth Ridge, while recreational and resource management points like Poison Creek Campground and Camp Four are situated along the interior drainages of Poison Creek and Gold Creek.
