Department of the Interior, National Park Service, Black Canyon of the Gunnison National Park 2003 vector digital data http://www1.usgs.gov/vip/blca/blcageodata.zip doi:10.5066/F7HD7SK6 This administrative boundary for Black Canyon of the Gunnison National Park (BLCA), Colorado contains 6 polygons showing National Park Service (NPS) lands, and private lands (3 parcels with conservation easements held by NPS with no public access, and 1 parcel without a conservation easement) that lie within the Park boundary outline. To show the Black Canyon of the Gunnison National Park boundary. The intended use of all data in the park's GIS libraries is to support diverse park activities including planning, management, maintenance, research, and interpretation. The Black Canyon of the Gunnison's unique and spectacular landscape was formed slowly by the action of water and rock scouring down through hard Proterozoic crystalline rock. No other canyon in North America combines the narrow opening, sheer walls, and startling depths offered by the Black Canyon of the Gunnison. 20000926 20030115 dataset verification Complete As needed Black Canyon of the Gunnison National Park -107.831187 -107.617152 38.644035 38.511665 None Boundary Administrative boundary Property Easements Land ownership Conservation easements Park boundary Land Use None North America United States USA Western USA Rocky Mountains Intermountain Region Montrose County Delta County Montrose Delta BLCA Black Canyon of the Gunnison National Park Black Canyon Gunnison River South Rim North Rim East Portal NPS National Park Service Colorado Western Slope US Gunnison Gunnison County None This dataset should only be used for general reference information purposes.

Vlahos - BLM Montrose, M. Reynolds - NPS 1999 vector digital data New park boundary created by 1999 legislation changing status from National Monument to a National Park www.nps.gov/gis/available_data.html The attribute accuracy is tested by manually comparing hard copy plots of the digital data with the source materials. When attributes cannot be visually verified on plots they are interactively queried and verified on screen. ARC/INFO software is used to create and maintain topological relationships between features. There are no duplicate features, but coincident lines are maintained between data layers where appropriate. Polygonal features begin and end at the same point, contain no overshoots or undershoots, and contain a single label. Complete The horizontal positional accuracy is tested by visual comparison of hard copy check plots to the source materials and verifying the location of the data on screen relative to other data layers in the same geographic area.

National Park Service, Black Canyon of the Gunnison National Park/Curecanti National Recreation Area - GIS Staff Unpublished Material vector digital data 24000 digital data file 2001 dataset update scncease Scenic easement arcs were appended to the BLCA boundary. Attribute data were verified against the original scenic easement data. The 1999 legislation boundary coverage arc vertices were adjusted to the arcs of the GCDB data (considered to be the most accurate data, representing 1/16th of a section) in those areas where they were slightly off of the GCDB lines. The boundary coverage was then built for topology in ArcEdit with the "build" command, and saved. The land status coverage was utilized for spatial reference. Scenic easement arcs were appended to the BLCA boundary with ArcEdit commands "Sel" and "Put". Corresponding attribute data were then filled in manually and verified against the original scenic easement data. The new BLCA boundary coverage was then built in ArcEdit and saved. Acres were then recalculated. legislation coverage BLM Land Status GCDB data scncease 20011219 blca_bdy2002 National Park Service, Black Canyon of the Gunnison National Park/Curecanti National Recreation Area GIS Specialist mailing and physical address
