About this map

Onion Mountain and the high ridges of Josephine County define this landscape of narrow canyons and complex hydrology as it appeared in the early 21st century. The map is heavily marked by the legacy of resource extraction, with several named mining sites including the Flanagan Mine and Murry Mine in the north, and the Ramsey Mine and Buckeye Mine further south. These sites sit at the headwaters of numerous drainages such as Pickett Creek and Shan Creek, which carve deep recesses like Midnight Gulch.

A network of forestry and development roads, such as Nat For Dev Rd 2706 and Waters Creek Rd, provides access across the drainage divides. Water is a constant presence on the sheet, from the steep drop at Taylor Creek Falls to several reliable water sources like Annie Spring, Rattlesnake Spring, and Root Spring. The drainages of Limpy Creek and Dutcher Creek illustrate the typical Pacific Northwest pattern of tributary networks feeding into the larger Slate Creek valley.
