Mill State Park, PA

I made a post Dec 2, 2005 concerning an old-growth area I'd
McConnells Mill State Park in Western Pennsylvania near the town
Portersville. The park contains the very scenic, steep-sided
Creek Gorge in and around which are scattered numerous stands of
In that Dec 2 posting, my first to the ENTS list, I listed girth
measurements for a number of trees, but no heights. At the time
neither a laser rangefinder nor a clinometer.
In mid-December I purchased a Nikon Monarch 800 laser
rangefinder and a
Suunto clinometer. I spent the most of my free time over the
Year's week practicing using both and studying Will Blozan's
Guidelines of the Eastern Native Tree Society."
By Saturday, January 7th I felt confident enough to take my
clinometer to McConnells Mill to get height measurements on some
trees I'd found on my many earlier visits. I went back the next
January 8th and again this past Sunday, January 22.
I mostly measured trees that I remembered as being particularly
of them tulip poplars. There are still plenty other tall trees
there that I
haven't got to yet.
Red Oak 13'9"
103.5' (Big one from my pictures)
Red Oak 12'2"
Tulip Poplar 10'11" 148.3' (146.1')
Tulip Poplar 6'3" 138.6'
Tulip Poplar n/a 137.8'
Tulip Poplar 9'8" 133.9'
Tulip Poplar 10'10" 130.9'
Tulip Poplar 9'8" 129.6'
Tulip Poplar 6'9" 127.5'
Tulip Poplar 9'8" 125.5'
Tulip Poplar n/a 125.1'
Tulip Poplar n/a 122.6'
Tulip Poplar 10'0" 121.7'
Tulip Poplar 9'5" 113.3'
Tulip Poplar 9'6" 108.5'
White Oak 11'1" 99.7'
White Oak 11'6" 95.1'
White Oak 11'4" 91.4'
The three tallest tulips I didn't get to until darkness was fast
Considering their great height I would have prefered to take
measurements of each. They are about a mile's walk through the
where I parked, so I only had time to make a single measurement
of all but
the tallest one. That tree I measured twice. First getting
148.3'. The two measurements were done from different positions
off of different branches. Due to the haste in which I had to
three trees, consider these height numbers to be tentative.
I should qualify all of the above measurements by saying that I
am still a
beginner with a number of questions regarding the finer points
measuring technique. I also have to say that my laser is as yet
uncalibrated. (I have been scrupulous, though, about only taking
clickover points.) The above said, however, barring some
problem with my laser, I feel confident that these height
represent at least fairly good "ballpark" figures.
I have to thank Dale Luthringer for answering many of my
questions through a number of emails that we've exchanged. He's
reassurance on a number points.
I will be returning to McConnells Mill this coming Saturday,
January 22 with
Ed Frank and Carl Harting. I look forward to remeasuring some of
trees with them. It will be a chance to check the accuracy of my
measurements and sharpen my measuring skills. Also, there is a
cucumbertree not on the above list whose I height I'd like them
before I post it. The trip will also be a chance to show some
people this amazing place.
I look forward to posting the results of our trip.
