1951 Map of Moores Hollow

USGS Topo · Published 1953

About this map

The confluence of the Snake River and Malheur River defines this high desert landscape along the border between Oregon and Idaho. In the early 1950s, the region's agricultural dependency is clearly visible through the extensive network of irrigation infrastructure, including the Owyhee Canal and the Moores Hollow Ditch. This water system supports the concentrated settlements at Annex and Ontario Heights, where community life centers on the Ontario Heights Church and the Ontario Heights Grange. The mapping captures a pivotal moment of transition, showing the historic path of the Oregon Trail alongside modern developments like the Ontario Airport and the Union Pacific railroad line. To the west, the terrain rises into the sagebrush-covered slopes of Tub Mountain and Pine Tree Ridge, broken by named landmarks like Malheur Butte and the broad expanse of the Alkali Flats.
