CZ1851 - TUCSON UNIV ARIZ OBS DOME - Tucson, AZ - U.S. Benchmarks on Waymarking.com

This station was first monumented by the CGS back in 1935. It is the top of the Steward Observatory dome (located at 933 N Cherry Ave) right on the campus of the University of Arizona in Tucson, AZ.

The NGS' currently posted coordinates ("N 32 13 59.47399 W 110 56 56.36586", or "N 32° 13.991 W 110° 56.939") seem reasonably accurate: I was unable to get a measurement right below the center of the dome, but based on average readings around the building itself I can assume that the NGS measurements are correct.

The station was recovered in good condition.
