1990 Map of Malheur Lake West

About this map

Malheur National Wildlife Refuge dominates this landscape, showing the complex interplay between the seasonal waters of Malheur Lake and the marshlands fed by the Donner Und Blitzen River. This 1990 edition records a specific moment in the lake's fluctuating shoreline, capturing the marshy expanse between Voltage and Sod House. The human footprint is concentrated along the southern edge, where topographic elevations rise above the wetlands. Here, researchers can find the Sod House Sch and localized industry represented by a Cinder Pit and Gravel Pit. The map is particularly useful for understanding the hydraulic character of Harney County, illustrating how drainage patterns across Cole Island and various unnamed landforms were documented before modern environmental shifts further altered the basin.
