I’m not sure what the proper term is for this effect, but there is (was) a glacier on the other side of this mountain in Seward, Alaska, and the resulting “cloud” came pouring in over the mountaintop one day when I was there.
The postal code in Stewart, British Columbia, is “VOT 1WO,” which the locals tell me stands for Very Old Town, One Way Out.
The image here shows two photos of the Pedersen Glacier in Alaska. The black and white image is from 1917, and the open green field is from 2005. I found those photos in this YouTube video after viewing a short video about how warm it is in the Arctic Circle this year, where glaciers are melting during the winter instead of forming new ice.
For more information, the USGS has this page which shows many more examples of disappearing glaciers in Alaska.
I don’t know the name of this glacier (or even this area), but I can tell you that this is a glacier and mountain range somewhere near Anchorage, Alaska. I took this photo in 2007, so there’s a chance that this glacier doesn’t exist any more.
These photos are of the Mendenhall ice caves in Junea, Alaska. See this Twitter page for the full images and more information.
