Frequently-asked questions:

What does this data set describe?

Title:
Idaho State Centennial Trail

Abstract: 
The Idaho State Centennial Trail extends about 1,200 miles from Nevada to the Canadian border. It passes through 11 national forests, 1,200 miles of rugged sagebrush desert, and the largest contiguous wilderness in the lower 48 states. 

The trail was designated as part of the 1990 Centennial Celebration. The idea for the long-distance trail was conceived when two Idahoans, Roger Williams and Syd Tate hiked a similar route in 1986. 

After extensive planning and public comment, the trail was officially designated by the Idaho Park and Recreation Board on June 1, 1990. Through the Board's designation, the Idaho State Centennial Trail became the first trail to be adopted into the State Recreational Trail System (Idaho Code 67-3232). The Idaho State Centennial Trail was designed using existing on-the-ground trails, and in some cases backcountry roads when connective corridors were needed. 

The creation of the Idaho State Centennial Trail was a cooperative effort of those listed below: 

Idaho Department of Parks and Recreation
Provides overall trail coordination. 

Idaho Centennial Commission/Lasting Legacy Committee
Endorsed trail as an official Centennial Project. 

Idaho Trails Council 
Coordination for trail signing and maintenance. 

Bureau of Land Management
Managers of southern section of trail. 

U. S. Forest Service
Managers of the middle and northern sections of the trail. 

Private and public land managers
Allow trail users to cross their property.

Supplemental information: 
In 2005, the Idaho Centennial Trail was mapped using Delmore Topo products. This information was then converted to a shapefile and reprojected into IDTM.

The information was checked using rasterized USGS Topographic Maps and U.S. Forest Service Trail Coverage layers.

Why was the data set created?

The trail passes through some of Idaho's most spectacular country. Elevations vary from 1,900 feet at the bridge crossing on the Selway River to numerous high-mountain passes ranging from 7,000 to 9,200 feet. The route traverses a variety of terrain including sagebrush desert, flower-filled alpine meadows, dense cedar forests, six major river canyons, and passes by numerous crystal clear mountain takes. Many unique geological formations, such as caves and hot springs, can also be seen from the trail. Along the way you will find Idaho as it was 100 years ago. Abandoned homesteads and cabins, old mines, logging camps and a restored, old time ranger station are many of the interesting sites along the route. The trail also crosses two national historic trails, the Oregon Trail on the Snake River plain and the Lewis and Clark Trail along the Clearwater-Lochsa divide. The Centennial Trail primarily crosses public land, but there are small segments of private land along the way. Permission to cross or camp on private land must be obtained from the land owner.
