I made another trip to Green Lakes this afternoon. More than anything, I'm trying to get better (and quicker) at identifying tree tops; however, I might as well collect some useful height data while I'm at it. The temperature while I was on my hike was around 40F, though rain started to fall after a little while, and the compacted snow had long ago turned to ice underfoot, thanks to the popularity of the park's trail system with the locals. It was a pretty comfortable outing, though I had to watch my steps very carefully. Now, on to the numbers:
I measured four hemlocks, all east of the tuliptree cathedral, past the power line right of way:
I'm uncertain if these trees have been measured before, as they're away from the main grove. The hemlocks growing among the tulips seem to top out in the 115-125' range, while the taller ones have no similar competition.
I measured two basswood, both on the northern-most trail between Green and Round Lake:
A Yellow birch in the same area came in at 87.8'. Many Yellow birch at Green Lakes have impressive girths, but fairly short trunks and lots of fine branches overhead.
On the northwest side of the tuliptree cathedral, among a group of similar trees, I measured a sugar maple to 121.7', and in the northeast corner, growing under hemlocks, I measured a beech tree to 108.0'.
On the south side of Green Lake, from the trail, I measured a Northern Red Oak to 114.6, and a Chinkapin Oak to 86.7'. The Northern Red has quite a buttress, and I'll make a point to record the girth in the future.
To round out the trip, I remeasured the lone white pine at the east end of Green Lake, next to the trail, at 121.2'. This pine, though in good color, is showing some age in the thinness of its crown, and I don't know how much longer it has before it starts to break down.
For now, my personal Rucker-10 Height Index for Green Lakes stands at 123.7'. My guess is that it'll settle closer to 130' when I'm done, though this may take a while. I may have to recruit Tom to help me.
