TillaMurphs Posted July 10, 2009 Share Posted July 10, 2009 We found an Azimuth mark with its own reference mark. Its reference mark is not listed in the NGS database. The azimuth mark was for POLLYWOG RESET (OA0935). At 11.8 feet west of the azimuth mark there is a disk. The disk is a U.S. Army Corps of Engineers station disk that appears to have been pressed into service as a reference mark disk. It has an obviously hand-scribed arrow pointing towards the azimuth mark (and a sideways “V” letter stamp was used for the point of the arrow). The azimuth mark's reference mark disk is stamped: POLLOYG A. R.M. 2 and looks like THIS and THIS. This leads us to 4 questions: How often do azimuth marks have their own reference marks (we have never come across one).. Is there any way to find out information about U.S. Army Corps of Engineers (USACE) disks?. Why would the station disk and the azimuth mark disk be USCGS disks and the azimuth mark reference mark disk be a USACE disk?. Why the hand-scribing of the arrow, and possibly the triangle, on the USACE disk? Thanks for any help! Bonus question #5 for extra credit: What do you suppose these things are: WHAT THE HECK? They were on the ground right next to the station and they survived a major forest fire that swept that through the area. They are 2.75 inches long and were lying exactly as seen in the photo. We first thought they might be battery cores. However, when we got home and measured, we found out they were too long for that. Quote Link to comment
