2020 Map of Haas Hollow

About this map

The Imnaha Wild and Scenic River carves through the heart of this landscape within the Wallowa National Forest, defining a drainage system where water and topography dictate the movement of people and wildlife. The elevation is marked by prominent named landforms including Grizzly Ridge and Haas Ridge, with the latter overlooking the eponymous Haas Hollow. This 2020 survey illustrates a sparsely developed region where human presence is largely limited to infrastructure like the Lower Imnaha Rimrock Rd, which follows the high ground above the river canyon. Numerous seasonal and perennial water sources such as Packsaddle Spring, Thorn Creek, and Fence Cr descend from the ridges, feeding into the primary Imnaha drainage. The map provides a contemporary record of local place names like Knapper Gulch and Pileup Canyon, which speak to the long history of livestock management and regional navigation in this part of Wallowa County.
