That's for ice at 0°C too. I make it a 34km drop for 1kg of ice to gain that much energy. Are we missing something?

- Animats 6y agoI wonder if that author was misquoted. He has a PhD in glacier hydrology.[1] He has to know there just isn't enough potential energy in falling ice to melt it rapidly.

- mkl 6y agoCould well be. Maybe it's about it falling to lower altitudes with higher temperatures, and the friction of the avalanche warms it a bit and breaks it up so it can melt quickly in the warmer air.
