NPS, Bighorn Canyon National Recreation Area, Resource Division 2003 vector digital data Polyline coverage showing a graphic of the boundary of Bighorn Canyon NRA. Data has been modified for large-scale mapping on an as-needed basis from the original source data (distributed National Park Service boundary file created and maintained by Dean Tucker). To provide a graphic depiction of the Bighorn Canyon NRA property boundary for management purposes. Bighorn Canyon National Recreation Area was established by an act of Congress on October 15, 1966, following the construction of the Yellowtail Dam by the Bureau of Reclamation. This dam, named after the famous Crow chairman Robert Yellowtail, harnessed the waters of the Bighorn River and turned this variable stream into a magnificent lake. 200207 ground condition Complete As needed -108.3176 -107.9537 45.3169 44.7537 None Recreation Area Historic Ranches Wild Horses Bighorn Sheep Yellowtail Dam BICA Boundary Area Perimeter Federal Land None Bighorn Canyon National Recreation Area Bighorn Mountains Crow Indian Reservation Fort Smith Lovell Montana Pryor Mountains Wyoming Yellowtail Habitat BICA Bighorn River US USA United States of America Bighorn County, MT Carbon County, WY Bighorn County, WY National Park System Unit Code ThesaurusBICA National Park System Unit Name ThesaurusBighorn Canyon National Recreation Area National Park Service Theme Category ThesaurusBoundary ISO 19115 Topic CategoryEnvironment none The digital park unit boundary should not be used for any legal boundary disputes.

All attributes were generated by ArcInfo during shapefile to coverage conversion. Topologically clean dataset. There are no duplicate features. Dataset reviewed manually with ArcInfo's ArcEdit module. No dangling nodes, sliver or open polygons are known to exist in the data. Topology has not been altered since last clean or build. Boundary file is updated as needed for large scale mapping (> 1:12000). Original boundary file (npsboundary) was created for small scale reference purposes only. Some areas of BICA are inaccessible and do not necessitate large scale mapping efforts. Boundary coverage was overlaid onto USGS DOQQs and known physical boundary features were used to visually reference the accuracy of the dataset. Based upon USGS DOQQs resolution, it is assumed that the dataset meets National Map Accuracy Standards (NMAS) of 1:12000. Ground-based accuracy assessments were performed to verify accuracy of heads-ups digitized features within the dataset. There is no vertical position record with this database.

This editing was performed using ArcEdit module of ArcInfo using known physical boundaries (fence lines, roads, streams, etc) by the process of heads-up digitizing over DOQQs. In some areas of importance, GPS field-collected data were used. npsboundary DOQQs 2002715 Lindsey McClennan Bighorn Canyon NRA Student Intern mailing and physical address
