Datasheet Description:
Reference Mark 1 is a standard USGS pipe cap stamped RESET 1946 4503 NOGLS and is set in a 5 inch diameter concrete monument projecting 1.4 feet and is marked with a wooden staff. The disk is badly beaten but in firm condition and is located 30 feet north of dirt road leading to triangulation station, about 58 paces southwest of the station mark and about 30 feet lower.
"NOGLS 4503 RESET" is a benchmark monumented by the USGS in 1946 located in Pinal County, Arizona. It is a reference mark that was remonumented as use for reference mark 1 for the benchmark SOTOL.
This disc is apart of the NOGLS vertical datum conducted during 1903, 1904, and 1905 across the Tucson area. To learn more about the NOGLS datum see this page.
I have my doubts about this being a disk from 1946 and not the origininal 1904 disc. I think the iron post might have been lose so they repositioned it and surounded the post with concrete.
The best way to get to "NOGLS 4503 RESET" is, starting at American Avenue and AZ 77, head on American Avenue to the junction of Mount Lemmon Highway. Turn right onto Mount Lemmon Highway.
