About this map

Mares Egg Spring emerges at the eastern base of the Cascade Range, where the steep timbered slopes of the Winema National Forest meet the flat reclaimed marshlands of the Wood River Valley. This landscape is defined by its transition from the Sky Lakes Wilderness down to a complex network of agricultural irrigation and water management. Numerous water sources including Blue Springs, Fourmile Springs, and Jack Spring feed into a system of man-made structures like the Sevenmile Canal and Melhase Ditch.

The presence of the Threemile Quarry and the Threemile Cinder Pit near Klamath Point indicates the geological activity and local resource extraction of the area. Engineering for water control is evident through numerous Weir labels and the North Canal, reflecting the intensive land use required for grazing in the valley. Historical routes such as Nicholson Road and Westside Road provide the primary access through this hydraulic and silvicultural landscape.
