Geologists from the University of Innsbruck unexpectedly found mineral deposits in former ice caves in the Austrian Alps dating back to the peak of the last ice age. These special calcite crystals demonstrate that intensive snowfall during the second half of the year triggered a massive glacier advance leading to the climax of the last ice age. The results were published in the journal Nature Communications.
