1990 Map of Ironside

USGS Topo · Published 1990

About this map

Ironside serves as the central hub of this Eastern Oregon landscape, situated at a junction of creek valleys and historical lines. A significant historical marker, the Old Indian Treaty Boundary, bisects the terrain, illustrating the formal division of lands in Malheur County. The hydrology of the area is defined by a network of drainage systems including Willows Creek, Boulder Creek, and Middle Willow Creek, which carve through the high-elevation terrain. Land use in this arid environment is highlighted by features such as the Rock Quarry Reservoir and Mud Flat Spring, suggesting the vital importance of water management and resource extraction to the local economy. The geography is further detailed by numerous named gulches and valleys, such as Sand Gulch and Lost Valley, reflecting a territory where topographic relief and seasonal water flow dictate the pattern of settlement and movement.
