discusses, among other things, density of the ice that forms the walls of the fumarolic ice caves in the crater of Mt St Helens.
The [St Helens summit crater] caves are called firn caves because their density ranges from 0.55 to 0.82 g/cm3...
The ice density in September 1994 at the base of this crevasse was 0.85 g/cm3. The ice density in the lowest cave passage was 0.86 g/cm3.
As far as I know, 0.86 is greater than 0.82. Right!?
