Summary
[edit]DescriptionDyatlov pass incident avalanche possibility map 2.svg |
English: Possibility of avalanche of tent site of Dyatlov pass incident. Red contours, height. Green contours, slope. Ovet 15 dagrees in specila conditions can occur avalanche,
over 30 dagrees avalanches are frequent. This maps shows that acalances can occur almost neat Dyalov incident tent site, |
