Hyalite-Porcupine-Buffalo Horn Wilderness Study Area

The Hyalite-Porcupine-Buffalo Horn Wilderness Study Area is located in south central Montana, USA. It is one of nine wildlife study areas (WSA) in Montana and lies within Gallatin National Forest, running approximately 36 mi (60 km) long and four to 12 mi (6 to 20 km) wide. There are 31 named mountains within the WSA. Mount Chisholm is the tallest at 10,335 ft (3,150 m) and has a prominence of 2,011 ft (613 m). The second tallest is Mount Bole with a height of 10,328 ft (3,148 m) and a prominence of 699 ft (213 m).

Geography

One of nine wildlife study areas (WSA) set aside by the state of Montana in 1977, the Hyalite-Porcupine-Buffalo Horn Wilderness Study Area spans 155,000 acres (62,726 hectares) across the northern Gallatin Range between Gallatin and Yellowstone Rivers within Gallatin National Forest. From Hyalite Peak it extends south to the northwest corner of Yellowstone National Park. It is located in Gallatin County, Montana.

The landscape encompasses valleys, cirque basins, and jagged peaks ranging from 5,500 ft (1,675 m) to 10,300 ft (3,140 m) in elevation. As a wilderness study area, it does not yet have the same protections and land use restrictions as officially designated wilderness areas. Rather, it is an interim step to becoming a wilderness area. Studies are done to measure the ecosystem integrity in order to show it could be worthy of official wilderness status.

The tallest mountains in the Hyalite-Porcupine Buffalo Horn Wilderness Study Area are Mount Chisholm (10,335 ft/3,150 m), Mount Bole (10,328 ft/3,148 m), Hyalite Peak (10,312 ft/3,143 m), and Ramshorn Peak (10,299 ft/3,139 m).

Geology

The Gallatin Range is a subrange of the Greater Yellowstone Rocky Mountains. It is primarily composed of gneisses dating back 3.8 to 2.7 billion years. Paleozoic and Mesozoic sedimentary rocks like limestone, shale, and sandstone overlay the metamorphic core.

Igneous intrusions are present throughout much of the sedimentary layers. The tectonic plate collision that uplifted the range occurred during the Cretaceous period. However, much of the landscape was shaped into its present state by glaciers during the Pleistocene.

Ecology

Vegetation zones with the WSA run from grassland to Douglas fir and/or limber pine, to lodgepole pine, spruce, and subalpine forest as elevations increase. The highest elevation forests have whitebark pine and the alpine zone has either tundra or turf. Huckleberries grow abundantly in the forest here. A few threats to the ecosystem include mountain pine beetles, dwarf mistletoes, spruce budworm, and white pine blister rust.

Seven species have been identified as focal species for measuring the functioning and health of the ecosystem – bighorn sheep, mountain goats, cutthroat trout, elk, grizzly bears, wolverines, and pikas. Other important species include Columbia spotted frogs, boreal toads, lynx, moose, beavers, and fishers. These species are important because they have been studied in nearby areas, are sensitive to climate and land use change, and sufficient data exists to study their status within the WSA.

The Gallatin elk herd, numbering some 5,000 - 6,000, summers in the high country here and spends the winter at lower elevations. Common birds in the ecosystem include robins, chickadees, nutcrackers, warblers, juncos, ravens, and vultures.

Human History

The Gallatin Valley has supported human life for more than 12,000 years, evidenced by a skull found that dates back to the time of the Clovis tribe. In the modern era, the valley never belonged to one single tribe and was shared by many including the Blackfeet, Crow, Northern Cheyenne, Salish Kootenai, Bannock, Lakota, Nez Perce, Flathead, Sioux, and Shoshone tribes. As settlers arrived during the mid-1800s, Native Americans throughout the region were forced off their lands.

Congress passed the Montana Wilderness Study Act in 1977, creating nine total WSAs including the Hyalite-Porcupine-Buffalo Horn Wilderness Study Area. At the time, about 55,000 acres (22,258 hectares) within this WSA were privately owned. Since then, the Forest Service has acquired over 37,000 acres (14,973 hectares). Wilderness areas are defined by four qualities – “untrammeled, natural, undeveloped, and solitude or a primitive and unconfined type of recreation.” Ongoing studies on the WSA measures these qualities via a host of ecosystem indicators.

Best Hikes in Hyalite-Porcupine-Buffalo Horn Wilderness Study Area

Recreators should be aware that grizzly and black bears live in this ecosystem and it is important to be bear aware and practice proper food storage techniques if camping out.

There are no official trails leading to some of the tallest peaks in the WSA. Mount Chisholm can be summited by experienced climbers. Mount Bole does not have an official trail but can be reached by starting in meadows north of Arden peak and ascending to the northwest.

Frozen waterfalls in Hyalite

Hyalite Peak

To summit the third tallest peak in the WSA (10,328ft/3,148 m), you’ll travel 14.5 mi (23 km) on an out and back trail that gains nearly 3,500 ft (1,065 m) in elevation. The trail is popular amongst hikers and backpackers so you are likely to see other people during the peak season of July through October. The first half of the trail is forested so there is shade, and there is a lake, streams, and waterfalls along the way. This is a challenging route and typically takes 8 hours to complete.

Emerald Lake and Heather Lake Trail

Hitting two lakes in one go, this 10.5 mi (16.9 km) out and back trail gains 2,165 ft (660 m) in elevation. From this trail, climbers can continue on to reach the summit of Mount Chisholm. Snowpack can remain until late into the summer season. This trail is popular for hiking, backpacking, and fishing and offers great views all along the trail.

Windy Pass Trail

This 7.7 mi (12.4 km) loop trail gains about 2,000 ft (610 m) elevation. In summer wildflowers grow abundantly along the trail but, as with the Emerald and Heather Lakes Trail, snow may remain at higher elevations until late in the summer. There are a few stream crossings and incredible views from the top. Visitors should note that the road to the trailhead is rough, so high clearance vehicles are best or allow extra time for slow going to reach the parking lot.

Palisade Falls

Palisade Falls is a 1.1 mi (1.8 km) out and back trail. The path is paved, making it accessible to wheelchair users and strollers. The trail gains less than 250 ft (76 m) in elevation and leads to a lookout point in front of the falls. The falls cascade 80 ft (25 m) from a vertical rock wall at the base of Palisade Mountain.
