Wyo. Stat. § 34-25-107
Wherever coordinates based on the Wyoming Plane Coordinate System are used to describe any tract of land which in the same document is also described by reference to any subdivision, line or corner of the United States public land surveys, the description by plane coordinates shall be construed as supplemental to the basic description of the subdivision, line or corner contained in the official plats and field notes filed of record, and in the event of any conflict, the description by reference to the subdivision, line or corner of the United States public land surveys shall prevail over the description by plane coordinates. Every recorded map, survey or conveyance, or other instrument affecting title to real property which delineates, describes or refers to such property or any part thereof by reference to coordinates based upon the Wyoming Plane Coordinate System shall also describe the property by reference and tie to a controlling corner monument of the United States public land surveys, if applicable.
