Blackhand Gorge State Nature Preserve

Post by Rand » Sat Jan 15, 2011 11:05 pm

For a general overview I'll just quote the ODNR website:
The prime feature of this preserve is a narrow, east-west gorge cut by the Licking River through the famous Black Hand sandstone formation. It also boasts the only bike trail in Ohio's state nature preserve system; more than 4 miles of bike trail wind through the preserve.

The preserve is rich in natural as well as early Ohio history.The name Blackhand, for which the preserve is named, originated from a dark, hand-shaped Indian petroglyph which was engraved on the face of a massive sandstone cliff along the north side of the river. The engraving was destroyed in 1828 when canal builders dynamited the cliff face, during construction of the Ohio-Erie Canal, which runs through the gorge. Sections of the canal towpaths and canal locks may be seen from the trails along the river.

The dry hilltops are dominated by oak-hickory mature woods along with Virginia pine and mountain laurel. Yellow birch, cherry birch and eastern hemlock grow on northerly exposures. It is an excellent site for viewing woodland spring wildflowers.

In google earth it looks like this (the horizontal FOV is ~ 2 miles)

Walking through the paved bicycle trail at the bottom of the gorge, the impression one gets is of an average forest on protected land in Ohio. i.e. an even aged stand hosting trees 7'-9' cbh and 80'-110' feet tall. Tuliptrees with an understory of hemlock dominate the lower slopes, grading into red oaks and finally drier white-oak hickory along the lip. Midway through the gorge there are a few older trees, but of only slightly larger size due to the steep slopes. Nothing outstanding caught my eye until I stumbled onto the side valley circled on the map. Here a northward flowing stream cuts a wide notch into the gorge slope, hosting a dense stand of young tuliptrees along it's gently sloping bottom.

And the measurements:

Against all odds, the 152' sycamore weasiles it's way to the top of the list. This the tallest sycamore I've found in ohio, eeking past the 151' found in the Old Mans cave.

Randy,

WOW! Awesome sycamore and aspen. The sycamore as a species may prove to be similar to tuliptree as far as a wide span of tall trees throughout the east (-20 feet).

Rand,

The tallest we have found in PA and in the Northeast in general is 148.7 on Baker Island in the Allegheny River Island Wilderness. Fantastic sycamore! So you have a the tallest in the region.

Randy,

Ohio is beginning to speak with a commanding voice through the efforts of you and Steve. We're all anxious to see what the two of you find as your search widens.

Randy-

Great report---the pics must have been taken in April, based on the Ohio buckeye leaving out in the second photo. I wish we had pines and mountain-laurel up here in the north. I'll have to check out the area if I ever get close to Nerk.

Steve,

Yup, the date on the pictures are april 10, 2010. The large flower trilliums were also putting on a nice display:

A lonely Chestnut sapling is also present, gamely growing toward the light after the demise of the neighboring red oak.
(the oak is ~ 2' diameter in the picture and broke off at ground level just a few years ago)

We'll see how long it lasts.
