2023 Map of Boulder Butte

About this map

The Greenhorn Mountains anchor this high-elevation landscape in Grant County, where the headwaters of the Middle Fork John Day River and numerous drainage systems like Big Boulder Creek and Sunshine Creek carve through the terrain. The area is defined by its designation within the Umatilla National Forest, the Malheur National Forest, and the protected North Fork John Day Wilderness. Seasonal grazing and remote settlement patterns are evidenced by named high-country clearings such as Bear Paw Meadow, Coyote Meadow, and McCalpine Meadow. Topographic prominence is found at Boulder Butte and Myrtle Butte, while geological features like Ragged Rocks and Coyote Bluff indicate the varied rock formations typical of this part of the Blue Mountains. This modern survey provides a detailed view of the forest road networks and water sources, including Sunshine Springs and Crockett Spring, which have supported remote activity in these mountains for generations.
