Here are a few pictures of a corner recovered last week. It was originally set in 1871, set wood post and mkd. a 10 in. burr oak and a 12 in. burr oak. No intervening records, straight woods and no sign of dozers! A small piece of a letter was found in a mostly decayed approx 2 ft. diam. oak stump for one BT and at the other BT position only a 3 ft mound with lateral root holes remain.
here is the piece of letter; and here is the LS setup on that stump;
here is the T2 setup on the mound collecting raw data for submission to DPOS
I used the LS as a RTN/VRS rover and collected data on both stumps-a RTK position and also recorded the raw data for submission to DPOS as a check. I used JMT and the T2 to collect raw data on the mound while using the LS to observe the stump, notice the rigged bipod, when on RTN/VRS I always bring the pole that came with the set and the T2 as a spare unit for static or RTN/VRS using JMT.
The data was very impressive for the conditions, the LS static positions were with in about .07 to .09 ft. of the RTN/VRS solution and the T2 position is with in .15 ft. of the RTN/VRS position. I chained between the 2 observed points(42.60 ft.) and the chained dist is .02 ft. different than the inverse of the RTN/VRS solutions(42.62 ft.). I can take that especially on a stump and a mound!!!
