For general use by Yellowstone National Park researchers and staff. This dataset is not field verified and has not been checked for errors.
Unlabeled polygons do exist in the data.
The feature boundaries were compiled from different scales. Used as base maps for digitizing. Wilderness boundaries were snapped to Yellowstone's boundary to enhance accuracy. Bridger-Teton National Forest''s GIS coordinator supplied this boundary information. Individual Forest Service maps were digitized using a CalComp digitizing tablet.
