Six 160'+ poplars and counting. Delaware.

I use a 440 Nikon rangefinder, a Suunto Clinometer, and a scientific calculator. The method is best described below in either of these articles by Will and Ed. Beyond that its just practice and getting good at determining the tallest limb. That being said, most of the trees in this post were easy. There were hardly any obstructions preventing an accurate laser reading. The canopies were leaf free and the trees were spaced well.

Thanks for the post. Lots of gorgeous big trees. I do love those Tulips.

Just a quick update to this post. I've found three more 160'+ tulips in this park and several other 15' CBH tulips.

10'6" x 160.5'
11'2 x 161'
12'3" x 160.5'

John,

So Brandywine Creek SP now has 9 TTs in the 160 club?

Bob,
Yes, 9 that I've found so far. George Fieo had found a 164' tulip that I haven't been able to find yet so I think there are a few more out there. I've been taking close-up photos of the trunks to make sure that I don't measure the same tree twice. Some of the 160'+ are literally a couple feet away from each other.

Johnny- Wow! Beautiful!!! What an impressive list those Tulips are really huge! You could get GPS on them so you could mark them on a grind or just have them cataloged for reference. I usually get GPS for the largest or tallest of a species that I measured. It might not be a bad idea for you. Tallest I've measured in the Deep South are in the mid 130's. Larry
