Visiting a USGS marker at 4,459 feet
Posted by David Brooks | Thursday, November 22, 2012
Our familiy hiked Mt. Liberty and Mt. Flume, in the Franconia Notch, for Thanksgiving. The weather was spectacular - hardly any wind at the top, incredibly enough. (Coming down the Flume Slide trail was a mistake, however; it's brutal.)
I don't know how many USGS survey markers exist in the Whites, but I got this picture of the one on Lincoln, with Cannon Mountain in the background. (The Old Man of the Mountain was once at the top of the Cannon sheer area.)
The funny thing is that while the marker had a space for elevation, it had no number listed there. It did have a date, though: 1964.
Wikipedia, no surprise, has a big article about USGS Survey markers.
