2017 Map of Sinamox

About this map

The Deschutes River carves a deep, winding path through this portion of north-central Oregon, defining the boundary between Wasco and Sherman Counties. The river's serpentine course is punctuated by Cedar Island and surrounded by a high plateau dissected by numerous drainages, including Box Elder Canyon and Oak Canyon. The remote station at Sinamox sits on the river's eastern bank, illustrating the area's isolation and its reliance on the river corridor for access. Further inland, the terrain rises toward Tygh Ridge, while local ranching or agricultural access is marked by corridors like Brown Rd and Payne Loop. The map also records the lower reaches of Elder Cr, showing how these intermittent water sources have shaped the local landscape and settlement patterns in this arid region.
