My second youngest study site at Glacier Bay is on a bench of outwash about 150 feet above Muir Inlet. Before alders covered the young surface in the mid 20th century, the bench offered a good view of the retreating face of Muir Glacier to the north. William O. Field established a photo station there maybe in the late 1940s and marked the spot with a cairn assembled of several large rocks (see http://fastie.net/dating-fred/). I found a cairn in 1988 when I set up my study plots in a dense thicket of alders.
