1948 Map of Dorsey Butte

About this map

The Snake River defines the southern reach of this 1948 survey, marking the border between Ada and Owyhee counties. The landscape transitions from the broad expanse of Chattin Flat in the south toward the distinctive volcanic prominence of Dorsey Butte in the north. This postwar era reveals a sparsely populated agricultural and ranching district, where essential local infrastructure like the Hayland Sch and a Landing Strip (Private) served a scattered community. Complex water management is evident through the network of canals and small water bodies such as Jack Spr and the curiously named Jack Flume Creek. The topography is punctuated by Chattin Hill, providing a clear record of the area's drainage patterns and livestock-based economy before later 20th-century developments altered the rural character of the region.
