About this map

The Sidwalter Buttes dominate the high desert terrain of Wasco County in this 2020 study, rising above a landscape defined by significant hydrological features. The Warm Springs River and its S Fork carve through the northern and central sections, supported by reliable water sources such as Warm Springs Meadows, Big Spring, and Nellie Spring. The naming of the local infrastructure, including Mount Wilson Schoolie Rd and Old Mill Schoolie Rd, suggests the historical importance of the Schoolie Pasture for ranching or community transit in this part of Oregon.

To the south, the topography transitions toward Mill Creek Flat and the Mill Creek Lateral, indicating an organized approach to water management in an area otherwise characterized by seasonal drainages like Badger Creek and Cedar Creek. The network of Bureau of Indian Affairs and local access roads, such as BIA Rd 3 and BIA Rd 35, underscores the connectivity within this part of the reservation lands.
