36th Annual North Cascade Glacier Climate Project Field Season Begins

Fieldwork includes terminus surveys, glacier runoff measurement and mass balance measurements Field Season Begins August 1 Who we are? The North Cascade Glacier Climate Project (NCGCP) was founded in 1983 to identify the response of North Cascade glaciers to regional climate change, particularly changes in mass balance, glacier runoff and terminus behavior.   This was prompted by the  National Academy of Sciences listing this as a high priority and a personal …

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 …

34th Annual, 2017 North Cascade Glacier Climate Project Field Season

2017 Field Season Video For the thirty fourth consecutive summer we headed into the field to monitor the continued response of North Cascade glaciers to climate change.  In 1984 when I began this program we selected 10 key glaciers to monitor.  Two of these have now disappeared.  All the glaciers have retreated extensively and lost considerable volume.  The mass balance loss is 19 m of water equivalent thickness, which is over …

Thirty-third Annual North Cascade Glacier Climate Project Field Season Underway

Base Map of the region showing main study glaciers, produced by Ben Pelto. From President Reagan to President Obama each August since 1984 I have headed to the North Cascade Range of Washington to measure the response of glaciers to climate change.  Specifically we will measure the mass balance of nine glaciers, runoff from three glaciers and map the terminus change on 12 glaciers. The data is reported to the …

Neve Glacier Retreat, North Cascades, Washington

I have had the opportunity to visit the Neve Glacier on eight occasions, it is not easy to get to. In the North Cascades it is one of a handful of glaciers with a large higher elevation accumulation zone, that is not on a volcano. The glacier feeds Diablo Lake, part of the Skagit River hydropower system. The terminus of the glacier in 1975 was in basin that receives considerable …

Suiattle Glacier Retreat and Outcrop Emergence, North Cascades

C.E. Rusk in 1906 hiked right to the terminus of Suiattle Glacier, which is labelled Lion’s Paw in Rusk (1924). The glacier had retreated 1400 m since its Little Ice Age maximum and based on the lack of reported brush below the glacier, this retreat had occurred primarily in the previous 30 years. By 1940 the glacier had retreated another 900 m back to within 120 m of its current …

Mazama Glacier Retreat, North Cascades, Washington

Mazama Glacier flows down the north side of Mount Baker, a strato volcano in the North Cascades of Washington. The glacier begins at the summit plateau, 3260 meters, and terminates at the head of Wells Creek 1470 meters. This is a glacier we visit briefly each summer since 1984, but is not a focus of detailed observations. In 2010 we descended from its divide with Rainbow Glacier at 2100 meters …

Ptarmigan Ridge Glacier Retreat and Separation, North Cascades

Ptarmigan Ridge Glacier is nestled on the north side of Ptarmigan Ridge in the North Cascades of Washington. This is a small glacier that has been retreating and has separated into several smaller glaciers over the last 20 years. From 1984-2010 we have visited this glacier every year assessing the terminus in half of those years, in others it has still been buried by snowpack. The main terminus has retreated …

Banded Glacier a new alpine lake

Banded Glacier comparison in 1998 (left) and 2011 (right) Google Earth images.  Red arrows and dots indicate 1998 terminus-margin.  Yellow arrow and dots indicate 2011 terminus-margin The Banded Glacier on Mount Logan in the North Cascades of Washington has retreated since 1950 creating a new alpine lake, that is not evident on USGS maps of the time. In 1960 the glacier was 450 m wide ending in a lake that …
