Abstract:
National Petroleum Reserve - Alaska Boundary
Formerly known as the Naval Petroleum Reserve No. 4, the 23-million acre area on Alaska's North Slope has a history of nearly 100 years of petroleum exploration. In 1923, mindful of the land's conceivable petroleum value, President Harding set aside these 23 million acres as an emergency oil supply for the U.S. Navy. In 1976, in accordance with the Naval Petroleum Reserve Production Act, the administration of the reserve was transferred to the Department of the Interior, more specifically the Bureau of Land Management, and was renamed to what is now known as the National Petroleum Reserve-Alaska (NPR-A).
The NPRA Boundary (arcs) are a composite of 6 sets of arcs that define the exterior boundary of the reserve.
Purpose: Arcs used to create the NPRA (polygon) Boundary.
Supplemental_Information:
1. Spatial Data Management System bearings and distances for NPRA -1836 arcs
2. High, High Water Line within USS 9571 - one arc
3. Connecting Line Between MC2, T11N, R39W and the point of intersection of the administrative lease line of the N.P.R.A. and the surveyed W. bdy. of the N.P.R.A. - one arc
4. Southern boundary of the N.P.R.A. from a point in unsurveyed township Sec19, T31N, R13E, KRM northeasterly along the Continental Divide to Closing Corner 1, T11S, R43W, UM - one arc
5. Final Administrative Lease Line of the National Petroleum Reserve - Alaska (administrative lease line) - one arc made up of 8011 points of Latitude and Longitude
6. Connecting Line Between SDMS cor_id 146914 - MC12 on E BDY, T2S, R3W, UM;MC5 on W BDY, T2S, R2W, UM AND SDMS cor_id 136696 - MC14 on N BDY, T2S, R2W, UM;MC7 on S BDY, T1S, R2W, UM. (Objectid = 1841)
