Description: This data contains the corporate boundary of the Matanuska-Susitna Borough. It is based upon the official legal description of the Borough which makes references to the Public Land Survey System, Latitude/Longitude Coordinates, and adjoining boundaries of the original Mount McKinley National Park as defined on U.S. Survey 2177. The data provides Borough staff, other agencies, and the general public with a clearly defined boundary that is consistent with other data (i.e. section line data). It is meant to be an improvement upon previous boundaries that were made available as part of the TIGER/line program of the U.S. Census Bureau.
