Honeycomb Glacier Retreat, Washington New Lake Lost Nunatak

Honeycomb Glacier in Google Earth imagery from 1998 and 2016.  The dark orange line is the 1998 margin, we mapped the margin in the field in 1995 and in 2002.  The light orange line is the 2007 margin and the yellow line the 2016 margin. Note crevassing diminished as well.  Honeycomb Glacier is one of the longest and largest glaciers in the North Cascades.   In 1979 it was 3.9 km …

Chocolate Glacier Retreat, Glacier Peak, Washington

From 1994-1997 we ran a four year project to survey the terminus response of all the glaciers on Glacier Peak, Washington to climate change. This was a century after a climb in the region by C.E. Rusk. Chocolate Glacier is the largest of the east side valley glaciers. The average retreat of Glacier Peak glaciers from the LIA to the 1958 positions was 1640 m. Richard Hubley noted that North …

Dusty Glacier, Glacier Peak, WA

In the 1990’s the North Cascade Glacier Climate Project undertook a study of all the glaciers around Glacier Peak, one century after they had been first observed by C.E. Rusk. This post focuses on one of those glaciers, Dusty Glacier on the Northeast side of the peak. In 1940 J.B. Richardson of the Forest Service photographed many North Cascade glaciers surrounding Glacier Peak. From 1946-1958 William Long, of the Forest …

Kennedy Glacier Retreat, Glacier Peak Washington

Kennedy Glacier drains the west side of Glacier Peak, near the headwaters of the Whitechuck River. At the turn of the century C.E. Rusk explored the glaciers around Glacier Peak that were retreating from their Little Ice Age maximum in the mid-19th century. The average retreat of Glacier Peak glaciers from the LIA to the 1958 map positions was 1640 m. From 1950-1955 Richard Hubley, University of Washington, completed the …

Vista Glacier, Glacier Peak WA Retreat

Vista Glacier is the northernmost of the large valley glaciers on the east side of Glacier Peak. The glacier begins at 2475 m beneath Kennedy Peak. We examined all of the glaciers around Glacier Peak in detail in the 1990’s to document their changes since observed by C.E. Rusk 100 years earlier. The glacier during the LIA joined the Ermine Glacier and extended down to 1345 m. By 1900 when …
