Andrew, What was the angle of the pole? Did you come up straight from below? Was the tape drop to midslope? Maybe the error is in the basal point?

The crown structure is pretty much the same as in your photo. I went out on the upper right branch/leader as you described and reached up with a 9 foot pole (9 ft. with a mark at 8 feet above where I hold the pole) to get the high twig. I did the same as you did, marked 8 ft. from the top then transposed across to mark 8' at a point on the branch offset to the left of the imaginary plumb line below the top twig. Last night I remeasured my pole to verify my marker is exactly 8 ft., it is. Anyhow something ain't quite right, I will try again when I get the chance. -Andrew Will Blozan wrote: > > Bob, > > Awesome day indeed! I am puzzled by the tape drop- something is not > right.
