About this map

The Malheur National Forest boundary defines the landscape of this eastern Oregon region, where steep drainage systems converge toward the John Day River. Private holdings like the Morgan Ranch are situated near the riverbanks, illustrating the historical pattern of homesteading and ranching in the fertile valley bottoms surrounded by public timberlands. Aviation and industry have left subtle marks on the terrain, including a remote Landing Strip and multiple quarries used for local road and resource management.

Water sources are vital markers throughout the high country, from named springs such as Bumblebee Spring, Eureka Spring, and Pole Spring to the numerous Stock Ponds that support livestock in the more arid reaches. The network of gulches—including Eureka Gulch, Mossy Gulch, and Winegar Gulch—drains into the primary tributaries of Isham Creek and Deardorff Creek, creating a complex topography of ridges and draws.
