About this map

Wrights Point stands as a prominent geological bench dividing the arid basins of southeastern Oregon during the late 20th century. This survey documents the complex hydrological patterns of the Harney Valley, where the Silvies River and its West Fork meander through a network of sloughs and man-made levees. The landscape is defined by its dramatic elevation changes, from the flat reaches of Sage Hen Valley to the steep, contoured slopes of Dog Mountain.

Water management is central to the area's utility, evidenced by the numerous check dams and irrigation infrastructure near McGee Slough. Isolated water sources like Lunch Lake and Weaver Spring provide critical landmarks in the high desert terrain. The presence of Dry Lake suggests the seasonal nature of the region's basins, while the sprawling Sunset Valley illustrates the expansive, open character of the high plateaus typical of Harney County.
