2023 Map of Aldrich Mountain North

About this map

The Aldrich Mountains dominate this Grant County landscape, providing a high-elevation backdrop to the John Day River valley. A site of particular historical note is the Aldrich Grave, located just south of the river and near the Cheechako Ranch. This area reflects the mid-elevation ranching and forestry economy of eastern Oregon, where irrigation infrastructure like the Stewart Ditch supports valley floor operations. High in the Malheur National Forest, the terrain rises toward peaks such as Little Aldrich Mtn and Aldrich Mtn. Several high-country water bodies, including Pinchot Lake, Roosevelt Lake, and Stewart Lake, are situated along the southern ridges. Travel through the high country is marked by Chilkoot Pass and landmarks such as Dead Pine, illustrating the importance of named points in this expansive timber and rangeland.
