1950 Map of Jamieson

About this map

The Oregon Short Line and Union Pacific railroads define the development of this Malheur County corridor at mid-century, connecting small agricultural hubs across a landscape shaped by irrigation engineering. The settlement of Lancaster, serving as the Willowcreek Post Office, sits centrally alongside the tracks, while Jamieson and Dennis anchor the rail line to the north and south. The region's reliance on water management is evident in the network of canals, including the Vale Main Canal, Owyhee Canal, and Gellerman Canal, which divert water toward Hope Flat. Notable landmarks like the Hendrix Siphon and Morrison Reservoir highlight the technical infrastructure of the era. To the west, the Bully Creek School served the rural population near the base of Sugarloaf Butte, while the rugged eastern terrain is marked by McCarthy Ridge and numerous seasonal springs like McDowell Spr and Beirman Spring.
