Calving in action: Muir and Mendenhall glaciers

The Muir glacier is in retreat and so is the Mendenhall. Repeat photography of the Muir Glacier is presented on the USGS site [https://www2.usgs.gov/climate_landuse/glaciers/repeat_photography.asp] with dramatic comparisons from the 1880s and 2005 from various vantage points. From 1941 to 2004, the Muir glacier receded 7 miles. The Muir glacier is shown below in the photo by LCGS Russ - Own work, CC BY 3.0, https://commons.wikimedia.org/w/index.php?curid=6488897

The time lapse view of the Mendenhall retreat is spectacular. View this on the Huffington Post at [https://www.huffingtonpost.com/entry/alaska-mendenhall-glacier-time-lapse_us_5668c19be4b009377b23c915]. The images below show the retreat over 2007 to 2015. The calving action through time is dramatic. 

The national Geographic site [https://blog.nationalgeographic.org/2011/09/15/mendenhall-glacier-now-and-then/] shows the difference between 1894 and 2008 (below). The retreat is close to 3 kilometers over that nearly 120 year period. This article also presents images of the Muir glacier retreat.
