Very believable. I went up there today with a couple of friends ( drove all the way from Fryeburg, Maine ) and we climbed to almost the very top. ( Was way to tired to try and make it over the very last fall at the exact top ). It is definitely an area that you will end up dead on if your not careful.
I found this forum/topic searching for information of other people who have made it to the very top. Is there a spring or something else at the top?
This was about halfway, and it was this steep for most of the way.
