Neil Humphrey, Professor of Glaciology and Geomorphology at the University of Wyoming, says that "the new photo of Dinwoody shows even more melting than I was expecting. I guess we really have had some very warm summers and mild winters."
From Meier, Mark F.. "Glaciers of the Gannett Peak-Fremont Peak Area, Wyoming." MS (Master of Science) thesis, State University of Iowa, 1951. Fig. 38, p. 111. Original caption: "Emergence of a medial moraine on Dinwoody Glacier. The crest of the moraine has been marked with a dotted line. This medial emerges about 2,900 feet below the nearest visible bedrock, and is continuous for about 1,600 feet. Note figure standing on near end of moraine. The lower end of this moraine is shown in Fig. 11." Brightness, contrast, and structure adjusted in Lightroom and Silver Efex Pro 2.
This is a no longer a medial moraine, but now a kame (the sandy and rocky crest) and kettle lake. The kame is composed of sand, gravel, rocks and boulders. It was gradually formed by running water from the melting of Dinwoody glacier, which carried intense amounts of debris into this depression of the retreating glacier. The debris overwhelmed the medial moraine photographed by Mark Meier in the prior image. It also buried one or more detached blocks of glacial ice of the terminus . As the detached ice melted, it rounded and formed a rounded depression, that then filled with water from the meltwater streams.
