ebinmaine 67,484 #1 Posted September 1 We started on Lawrence rd in Pownal. Walked about a mile and a half around Tryon Mt. Explored a feldspar mine that we didn't know about. VERY interesting place. Video below and some pics mixed in. We walked over to Bradbury mountain State Park along the border trail and others. Then back to the parking lot. Total mileage just under 6. Elevation gain almost 900 feet. The humidity was high and doing its best to snot beat me. Nearly succeeded bit eventually I won. I wanted to make sure I called out this Pic first. Note the ring around this tree about 3 feet up. There was a cable tied to/around it in the distant past that was part of the mining operation. It was pointed directly at the tall post/crane/derrick in the video. More mine pics. This is a Pound for loose large animals from a couple hundred years ago. Super cool van in the State Park lot. And the rest..... 3 4 1 Share this post Link to post Share on other sites

Ed Kennell 38,170 #3 Posted September 1 Any idea what the mineral was used for? 1 Share this post Link to post Share on other sites

Found this while poking about: According to the Maine Geological Survey for Bradbury Mountain compiled by Henry N. Berry IV, “Feldspar is the most abundant mineral in granite, and in pegmatite the individual feldspar crystals can be very large. Feldspar was mined from pegmatite bodies like this in many places across Maine in the early 1900s. The quarry itself, now overgrown with large trees, is about 150 feet long, 20 feet wide, and 10 feet deep. It was crushed and separated to be used in making ceramics or as an abrasive. By the mid-1900s, feldspar mining had moved to other parts of the country and the world.” 1 Share this post Link to post Share on other sites
Handy Don 12,217 #5 Posted September 2 Fairly sure that the guyed pole is from a jib crane, the arm being attached at the base or between pairs of the angled brackets higher up. 1 Share this post Link to post Share on other sites

Our friend had the same thought. There are piles of debris within a certain reach to that pole. Share this post Link to post Share on other sites
Ed Kennell 38,170 #7 Posted September 2 Sure does Don. Looks like a bearing at the top that would allow the pole and jib to rotate. You can see the jib mounting bracket that would allow the jib to elevate and the angle brackets to mount winches for hoisting the load and to elevate the jib. Would be interesting to see the base plate. 1 Share this post Link to post Share on other sites
