The '''Tobacco Root Mountains''' lie in the northern [[Rocky Mountains]], between the [[Jefferson River|Jefferson]] and [[Madison River|Madison]] Rivers in southwest Montana. The highest peak is [[Mount Jefferson (Montana)|Hollowtop]] at {{convert|10604|ft|m|0}}. The range contains 43 peaks rising to elevations greater than 10,000 feet (3048 m).
Much of the central part of the range is within the [[Beaverhead-Deerlodge National Forest]], although many, mostly small patented mining claims exist within the forest boundary. The range saw significant gold mining, especially during the 1880s to 1930s.
The high peaks have been extensively glaciated, and most of the larger stream valleys held valley glaciers during the [[ice age]].
== Discovery and Nomenclature ==
When [[Lewis and Clark]] came through southwest Montana in 1805, they named many rivers — but if they referred to the mountain ranges by name, the names are not recorded. The 1865 DeLacey Map of Montana Territory does not name the Tobacco Roots. The first written reference to the mountains between the Madison and Jefferson Rivers is [[Ferdinand Vandeveer Hayden|F.V. Hayden’s]] 6th Annual Report of the Geological Surveys of the Territories for 1873, in which the name South Bowlder Range is mentioned, a reference to the largest river in the north part of the mountains. Although this usage (usually spelled “South Boulder Range”) is followed in many Geographies and Atlases of the 1890s and early 1900s, the USGS Three Forks Folio <ref>Peale, A.C., 1896, Three Forks Folio, U.S. Geological Survey</ref> labels the mountains “Jefferson Range.”
The earliest known use in print of the name Tobacco Root Mountains is Winchell’s (1914) report on mining districts of the Dillon Quad.<ref>Winchell, A.N., 1914, ''Mining Districts of the Dillon Quadrangle'': USGS Bull. 574</ref> The name was also used by Billingsley in a 1918 paper on the [[Boulder Batholith]], published by the American Institute of Mining Engineers. “Tobacco Root” appears in most subsequent publications, including Montana Bureau of Mines and Geology reports (at least since 1933), National Forest Maps (since 1938), and the Official Montana Highway Maps.
However, a map in Fenneman’s ''Physiography of Western United States'' (1931) shows a long Jefferson Range to include what is now called the Tobacco Roots plus the [[Gravelly Range]]. Oil Company highway maps from the late 1960s and early 1970s show “Tobacco Root Mountains” in the north, and “Jefferson Range” in the south (northwest of [[Ennis, Montana|Ennis]] and north of [[Virginia City, Montana|Virginia City]]). Preliminary topographic maps of the area (Bureau of Reclamation, Missouri Basin Project) from 1947-48 show Jefferson Range, but on the 1950 15-minute sheet (Harrison Quad) the identical topography is labeled “Tobacco Root Mountains” in the same place as “Jefferson Range” on the maps that were just two years older.
The 1947 Bozeman 1:250,000 shaded relief map has Jefferson Range, but the 1958 (Bozeman 1:250,000) and 1962 (Dillon) regular editions use Tobacco Root Mountains.
== Origin of Name ==
The basis for the name Tobacco Root is unclear. John Willard <ref>''Adventure Trails in Montana'', by John Willard, sponsored by Montana Historical Society, 1971</ref> says “Indians and early trappers found a root in these mountains that, when dried and mixed with larb, made a suitable substitute for real tobacco. The root was a species of [[mullein]].”
The term "tobacco root" is also an old name for species of [[arnica]]; native and European-introduced arnica are wildflowers in Western Montana, including the Tobacco Root Mountains.
Tansley, Shaffer and Hart (1933)<ref>Tansley, W., Schafer, P.A., and Hart, L.H., 1933, ''A geologic reconnaissance of the Tobacco Root Mountains, Madison County, Montana'': Montana Bureau of Mines and Geology Memoir 9</ref> attribute the practice of drying a species of mullein and mixing it with [[kinnikinic]] ([[bearberry]]) to replace tobacco to John Edwards, a prospector from Flint Creek, in the 1860s. He also gave the name to the hills in which the root was found. Kinnikinic, as the name of a mixture and not the bearberry plant, was a leaf-bark mixture, including [[sumac]] and [[dogwood]] leaves, smoked by Indians and pioneers in the Ohio Valley in the 18th Century. It was probably more or less the same as the “larb” mentioned above.
Other sources have reported the root to be a variety of the [[bitterroot]], Montana’s protected state flower. [[Shoshone]] Indians reportedly cooked the root and ate it, and it supposedly smelled like tobacco.
==Geology==
The center of the range is occupied by the Tobacco Root [[Batholith]], thought to be a satellite [[pluton]] of the [[Boulder Batholith]].<ref>Reid, R.R., 1957, ''Bedrock geology of the north end of the Tobacco Root Mountains, Madison County, Montana'': Montana Bureau of Mines and Geology Memoir 36</ref> This [[Late Cretaceous]] granitic body [[intrusive|intrudes]] [[Archean]] [[gneiss|gneisses]] and [[schist|schists]]<ref>''Precambrian Geology of the Tobacco Root Mountains, Montana'', John B. Brady, H. Robert Burger, John T. Cheney, and Tekla A. Harms, editors, Geological Society of America Special Paper 377, 2004</ref> Significant gold deposits appear to be related to the intrusion of the Tobacco Root Batholith and northwest-trending faults in the [[Pony, Montana|Pony]] area and elsewhere. The northern flank of the Tobacco Roots consists of [[Sevier orogeny|thrusted]] and folded sedimentary and volcaniclastic rocks ranging from [[Proterozoic]] [[Belt Supergroup]] strata to [[Cretaceous]] [[Elkhorn Mountains|Elkhorn Mountains Volcanics]]. Thick sections of [[Paleozoic]] and [[Mesozoic]] strata, including the [[Flathead sandstone]] and [[Madison Limestone]], are present. <ref>''Tectonic controls for thrust belt and Rocky Mountain foreland structures in the northern Tobacco Root Mountains - Jefferson Canyon area'', southwestern Montana, by C.J. Schmidt and T. E. Hendrix, Montana Geological Society Guidebook, Southwest Montana, 1981, p. 167-180.</ref>
== Land Characteristics and Habitats ==
The land is used mostly in [[livestock]] grazing and [[logging]]. Land stewardship in the North Tobacco Root Mountains and Foothills area is as follows:
*U.S. Federal Agencies: 32,309 acres, or 14.4% of total area, which include:
*BLM: 17,544 acres, or 7.8% of total area
*USFS: 14,765 acres, or 6.6% of total area
*State Agencies: 20,695 acres, or 9.2% of total area
*Private: 171,985 acres, or 76.4% of total area[http://fwp.mt.gov/content/getItem.aspx?id=26488]
There are 244 [[Terrestrial animal|terrestrial]] [[vertebrate]] species that are found within the
North Tobacco Root Mountains and Foothills including [[whitetail]] and [[mule deer]], [[elk]], and [[American Black Bear|black bears]]. The area is also habitat to a handful of "Tier I" species (Montana Fish Wildlife and Park's classification of nativie species with greatest need of conservation[http://fwp.mt.gov/content/getItem.aspx?id=26526], including the [[Western Toad]], [[Flaummulated Owl]], [[Bald Eagle]], Townsend's [[Big-eared Bat]], [[Grizzly Bear]], and [[Canada Lynx]], who are all under threat of Habitat loss, degradation, and fragmentation, especially as a result of population growth/development[http://fwp.mt.gov/content/getItem.aspx?id=26488].
