10008 — NGS RD4293 — Clark County, US

This triangulation station is part of the National Geodetic Survey's network, which establishes the fundamental control framework for surveying and mapping throughout the United States. Located in Clark County, Washington, at coordinates 45.69389° N, 122.55250° W, this trig point serves as a precise horizontal reference for regional geodetic work. Triangulation stations of this classification were historically positioned to provide accurate positional control across large areas through intervisible networks. Such monuments remain valuable for verification of modern positioning systems, resurveys, and establishing local coordinate references where high accuracy is required. The documented coordinates and station recovery information support continuity of the national spatial reference system. Verification and maintenance of benchmark locations like this preserve institutional surveying knowledge and enable professionals to maintain consistency in cadastral, engineering, and infrastructure projects across the region.
