Tobacco Root Traverse Report
A detailed trip report documents a full traverse of Montana's Tobacco Root Mountains, which form the western skyline from Bozeman. The journey begins at the northernmost peak and proceeds across the range, offering sunrise views and challenging terrain for ambitious hikers and backcountry skiers.
The Tobacco Root Mountains, a subrange of the northern Rocky Mountains, are framed by the Jefferson and Madison Rivers in southwestern Montana. Before being officially named the Tobacco Root Mountains in a 1914 mining report, the range was referred to as the "South Bowlder Range" in 1873 and later as the "Jefferson Range." The name's exact origin is uncertain, but one theory suggests early trappers and miners mixed dried native plants like arnica and kinnikinic with mullein as a tobacco substitute. Another possibility is that the name comes from the bitterroot, Montana's state flower, whose cooked root was said by early settlers to smell like tobacco. This range is a dense concentration of high peaks, with 43 summits exceeding 10,000 feet in elevation. The highest among them is Hollowtop Mountain, reaching 10,604 feet. Much of the central part of the range is located within the Beaverhead-Deerlodge National Forest. The mountains are primarily composed of a large mass of igneous rock known as the Tobacco Root Batholith, which dates back to the Late Cretaceous period. This geological formation is linked to the significant gold deposits that spurred a mining boom in the area from the 1880s to the 1930s. Signs of this extensive mining history, with some relics dating back to the 1860s, are scattered throughout the range. The discovery of gold in nearby Alder Gulch in 1863 drew prospectors to the area, leading to the establishment of historic mining towns like Virginia City and Nevada City on the southern end of the range. Today, the Tobacco Roots are a hub for recreation, offering numerous hiking trails, fishing in alpine lakes, and opportunities for mountain biking and horseback riding. The range is home to a diverse array of wildlife, including one of Montana's largest populations of mountain goats, as well as elk, bears, and mountain lions.
