2017 Map of Haas Hollow

About this map

The Imnaha River carves a deep path through this corner of the Wallowa National Forest, defining a landscape where steep canyon walls meet high plateaus. This 2017 survey details a network of canyons and gulches, including Pileup Canyon, Crooked Canyon, and Knapper Gulch, which drain toward the river from the high country of Grizzly Ridge. The map illustrates the specialized infrastructure required for this isolated terrain, such as the Power Line Rd and the vital Dug Bar Rd which provides access to the river's lower reaches.
