A device for measuring the penetration hardness (also called the ram resistance) of snow or firn, a quantity formerly believed to be a reliable guide to the density, and still commonly used in assessm
ents of the risk of snow avalanches.
A cone-tipped metal rod designed to be driven downward into deposited snow. The measured amount of force required to drive the rod a given distance is an indication of the ram resistance of the snow (
see snow hardness). (Swiss rammsondecone tip angle 60
