There are many North Cascade glaciers that are disappearing. In 1993 I published the first report of glaciers I observed disappearing (Pelto, 1993). Below is a list of North Cascade glaciers that we worked on when they were glaciers and have now disappeared. Images of selected glaciers lost around Washington State is below this table. Glaciers that have and are disappearing lack persistent accumulation zones. That is many years at the end of the summer there is no significant retained snowcover. This happens particularly on glaciers that lack avalanche accumulation, this applies to most slope glaciers. Pelto (2010) survival forecast method expanded on this point.

Table Mountain Glacier was a small but active crevassed glacier in 1985 when we first explored it. By 2009 it had lost most of its activity and size. By 2023 the glacier had fragmented into small inactive segments and is no longer a glacier.

Camp Kiser Glacier is a glacier that was draped across a peak on the northern edge of the Camp Kiser area off of Ptarmigan Ridge. The glacier had crevassing and was active in 1990. By 2015 it was no longer active and by 2023 almost all relict ice was gone.

Triplets and Cascade Pass Glaciers were active and crevasses during our observations from 1986-2003. From 2021-2023 rapid are loss occurred and these are no longer glaciers.

Hinman Glacier in 1958 USGS map and 2022 Sentinel image. The glacier went from the largest glacier between Mount Rainier and Glacier Peak to not existing by 2022. Above in 1998 Google Earth and 2009 image. There are a few small patches of remanant ice with areas of ~.01 km² 

Van Trump and Pyramid Glacier on Mount Rainier no longer exist after the hot summers of 2021 and 2022 led to further fragmentation and area reduction. No single segment of ice exceeds 0.05 km². Below is USGS map of region and 2019 image when the largest fragments still qualified as a glacier.

Anderson Glacier Olympic Range was a substantial glacier in 1959, that rapidly deteriorated after 1990 and was gone by 2009.

Conrad Glacier in Goat Rocks reaches Conrad Lake in the USGS map, by the time we mapped the glacier in 1993 it terminated 190 m from the lake, see images below, but was still a substantial glacier with an area of 0.2 km^2. By 2006 it had retreated onto the upper slopes and by 2022 there was only four patches left none exceeding .0.04 km².
