I was able to easily recover the USGS station mark from 1905 as well as Reference Mark #2. Unfortunately, it looks like Reference Mark #1 has been destroyed as well as the Azimuth Mark. I searched for RM 1 in the bushes where I believe it should have been but to no avail. The last datasheet log from 1977 mentions that RM 1 is lost. As for the Azimuth Mark, there was a new bridge built to replace the previous one a number of years ago and unfortunately, the AZ Mark was destroyed in the process. There are three new benchmarks that were monumented at this bridge and I've waymarked them and can be visited
here. Reference Mark #2 was found in poor condition due to lots of nicks on the disk face. I should also mention that this station shows on a topography map as 'North Base 4191.6'. There is also the stamping of 'NORTH BASE TRI STA 1905' as well as the elevation stamping of '4191.6' on the disk face.
The NGS datasheet history is adequate for station mark and RM #2 recovery with exception to RM #1 and AZ Mark:
