The map depicts Township 13 South, Range 12 East of the Gila and Salt River Meridian in Arizona and documents a boundary survey investigation conducted to determine the positions of existing survey monuments and private lands within NPS Tract No. 02-216, a 60.10-acre parcel. The investigation identified survey monuments previously set by various land surveys, including a 3/8-inch rebar with 15-inch aluminum cap marked "SETTLEMEYER R.L.S. 7599" at the northeast corner and additional corner markers at specified locations. The survey notes indicate that a comprehensive search was conducted for angle points, with 600 nails recovered during fieldwork. The document includes specific coordinate data, distances, and directional bearings for identified monuments and property corners, with detailed notations regarding ground conditions and monument specifications. The survey was conducted using RTK GPS and GNSS instrumentation to establish precise geographic positioning in accordance with NAD83 standards and the Positional Accuracy of Cadastral Surveys When Using Global Navigation Satellite Systems guidelines.
