This triangulation station is part of the NGS network, which maintains the fundamental geodetic control infrastructure for the United States. As a trig point, this benchmark served as a primary control station for surveying and mapping operations, establishing horizontal positions with high precision. Located near Portland, Oregon at coordinates 45.61460°, -122.67787°, this station contributes to the regional geodetic framework essential for surveying, engineering, and mapping projects throughout the Willamette Valley area. Triangulation stations of this type were historically observed and monumented to provide accurate reference positions for downstream surveys. Verification and documentation of such points remain valuable for professionals undertaking precision surveying work, as these monuments may still serve as control references or provide historical geodetic context. Recording the status and recovery of benchmark monuments helps maintain the integrity of the survey network for current and future applications.

Geodetic context in United States

The national geodetic reference in United States is maintained by National Geodetic Survey (NGS). The active datum is NAD83(2011) / NATRF2022 (active). Coordinates shown on this page are expressed in WGS84 (ETRF/ITRF-compatible) which is directly usable in most modern GNSS receivers. For cadastral work in United States you may need to convert to the local datum using the Coordinate Hub.
