There are two experimental forests in Montana established by the U.S. Department of Agriculture, Forest Service, Intermountain Research Station (INT). Both experimental forests are administered by INT's Research work Unit, RWU-4151, Silviculture of Subalpine Forest Ecosystems. Tenderfoot Creek Experimental Forest (TCEF) is east of the continental Divide and is located 24 miles north of White Sulphur Springs and 9 miles northwest of Highway 89 at Kings Hill in central Montana. All of the 8,874 acre (area obtained from Lewis and Clark National Forest Geographic Information System) experimental forest drains into Tenderfoot Creek which flows westerly into the Smith River and then into the Missouri River and into the Mississippi River system. The administrative headquarters for TCEF is located at the Intermountain Research Station's Forestry Sciences Laboratory in Bozeman, Montana. The majority of the hydrologic data for TCEF was compiled by Farnes, McCaughey, and Hansen (1995).
