A brand new Glacier has formed in Washington on top of an active volcano. This is strange because glaciers and volcanoes don’t usually coexist well. To form a glacier, snow needs to pile up faster than it can melt and harden over time. When Mount St Helens erupted in 1980, it left behind a crater that created a shaded area where snow never fully melted. This caused the snow to build up over a few years, forming a baby Glacier. The glacier even survived the volcano’s eruption again in 2004, as the ice simply squeezed like Silly Putty to let the lava through and kept on growing.
