On my thru-hike in 2008 I was told this story by a local/former thru hiker that there was a rock outcropping on the West Peak of Bigelow Mountain, and if you climbed down off the front of the rock outcropping there was a plaque to Myron Avery with his actual pickaxe set into to plaque. The individual who told me this story was very specific in his description and he was definitely not talking about the obvious plaque that can be found on Avery Peak. He said you would essentially need to climb down the face of the overlook, and it would be in a spot where very few would ever find it. Aparently Avery can be seen carrying his pickaxe in many photos.
When I arrived at the spot I found a rock outcropping as described, and climbed down a little bit but didn't find anything. Has anybody seen this or even heard of this story? It's possible my leg has been pulled but the story really intrigued me, enough to where if I were headed up to Maine I would head there to look some more.
