Helena National Forest

Covering a wide swath of the west-central portion of the US state of Montana, Helena National Forest is a federally-managed area of public land. The forest contains 67 named mountains, the highest and most prominent of which is Mount Edith (9,495ft/2,894m).

Helena National Forest


Helena National Forest contains some 1,538 square miles (3,984 sq. km) of land in west-central Montana. The forest is broken up into several non-contiguous sections within Montana, near the state’s borders with Idaho and Wyoming. Parts of the forest are within a number of different counties, including Lewis and Clark, Powell, Broadwater, Jefferson, and Meagher Counties.

Technically, Helena National Forest and Lewis and Clark National Forest to the north and east were administratively combined in 2015. These days, they are both managed by the US Forest Service as part of the Helena-Lewis and Clark National Forest though they cover different areas.

Helena National Forest is located in a highly mountainous section of Montana, in an area that’s a patchwork of public and private land. It is located to the northeast of the Absaroka-Beartooth Wilderness Area and to the north of the Beaverhead-Deerlodge National Forest.

Moreover, the Bitterroot National Forest separates Helena National Forest from Montana’s border with Idaho to the west. Finally, Lolo National Forest and the Bob Marshall Wilderness Area are located to the north of Helena National Forest.

Within Helena National Forest, there are parts of a number of different mountain ranges. These include the Elkhorn Mountains, the Boulder Mountains, the Lewis Range, and the Big Belt Mountains.

Helena National Forest also contains the Gates of the Mountains Wilderness and parts of the Scapegoat Wilderness, which is also managed as part of the Bob Marshall Wilderness Complex.


The peaks within Helena National Forest are part of the Central Montana Rocky Mountains, which are a subsection of the great Rocky Mountain Range, which extends for some 3,000 miles (4,800km) from northern British Columbia in Canada all the way to New Mexico in the United States.

Mountains. Helena National Forest

For the most part, the mountains within the forest formed during the Laramide orogeny, which was a major mountain building event that took place some 80 to 55 million years ago.

During this time, the Farallon and Kula plates subducted under the North American Plate, forming a number of Rocky Mountain subranges and other parts of the North American Cordillera throughout Canada, the United States, and Mexico.

That being said, Helena National Forest covers a number of different ranges, each of which have unique geologic histories.

For example, the Elkhorn Mountains and the Boulder Mountains are a part of the Boulder Batholith. The Boulder Batholith is a massive collection of various igneous plutons that formed during the Late Cretaceous and is primarily granitic in composition.

Alternatively, the Big Belt Mountains to the east are part of the Belt Supergroup geologic formation, which is primarily Precambrian sedimentary rock. The Belt Supergroup extends for some 77,200 square miles (200,000 sq. km) into Wyoming, Idaho, Montana, and even southern Canada, where it is known as the Purcell Supergroup.

Moreover, the Lewis Range, part of which is included as part of the northern section of Helena National Forest and extends into southern Alberta, is a part of the Lewis Overthrust. The Lewis Overthrust that dates back some 170 million years and resulted in the faulting of Precambrian rock on top of a significantly younger layer of Cretaceous bedrock.

There are a number of major peaks within Helena National Forest, including Mount Edith, Mount Baldy, Elkhorn Peak, Crow Peak, and Red Mountain. Moreover, the Continental divide travels through Helena National Forest, most notably as part of the Scapegoat Wilderness.

Flora and Fauna

Due to its large area, Helena National Forest is home to a diversity of flora and fauna.

At lower elevations, the forest is dominated by grasslands and sagebrush with some pockets of lodgepole pine. In more mountainous regions, Helena National Forest is covered in coniferous forests, including large stands of Engelmann spruce, Douglas fir, and ponderosa pine.

Wildlife is abundant in the region, too. In the Elkhorn Mountains, in particular, there is a sizable population of elk. Moreover, black bears, brown bears, bighorn sheep, mountain goats, mountain lions, Canadian lynxes, timber wolves, white-tailed deer, mule deer, beavers, muskrats, and wolverines are found in the forest.

Helena National Forest also has thousands of acres of rivers and streams which offer excellent fly fishing opportunities. Some of the main fish species in the region include westslope cutthroat trout, rainbow trout, brook trout, and northern pike.

Finally, bird species, such as bald eagles, peregrine falcons, red tailed hawks, and grouse can be found within Helena National Forest.

Human History

Western and west-central Montana have been home to humans for thousands of years. A number of groups, including the Blackfeet Nation, the Cheyenne, the Sioux, the Crow, the Shoshone, and the Confederated Salish and Kootenai Tribes, lived in and around the region that would later become Helena National Forest long before Europeans and European-Americans knew of its existence.

Lewis and Clark’s 1803-1806 expedition traveled through what would later become Helena National Forest. In particular, they expedition passed through the modern day Gates of the Mountains Wilderness in 1805, making particular note in their expedition journals about the prominence and beauty of the area’s grey cliffs at the entrance of a canyon along the Missouri River.

In the 1860s and 1870s, the region once again rose to prominence within the United States after gold, silver, and other precious metals were found in the region, particularly within the Elkhorn and Boulder Mountains.

Many immigrants to the region traveled along the Montana Trail from Utah, through Idaho, and into Montana. The trail was also critical for transporting supplies, food, and goods from Salt Lake City, which also served as an important commercial center for mining activities throughout the intermountain region.

After the heyday of mining in Montana, the regional economy shifted more toward agriculture and ranching. During President Grover Cleaveland’s administration, however, a number of large forest reserves, including the Lewis and Clark, Big Belt, Elkhorn, and Helena Forest Reserves in Montana, were created.

By 1907, the term “National Forest” was used to replace “Forest Reserve.” One year later, the Forest Service created Helena National Forest by combining many of the region’s smaller reserves.

As a result of the Great Depression and the formation of the Civilian Conservation Corps, Helena National Forest saw a massive increase in infrastructure, including campgrounds, roads, trails, and other recreational facilities. Throughout this time, the US Forest Service has managed Helena National Forest both for recreation and for commercial timber production.

In more recent years, Helena National Forest has stepped up its archaeological and cultural heritage programming, working to protect the region’s historical artifacts for generations to come.
