Photo by @daisygilardini / I visited this wonderful cave in Svalbard in early spring, when temperatures were still well below freezing. Glacier caves are ice caves that form under the ice of a glacier. They often originate as rivers that flow under the glacier during the summer months, when the glacier’s surface ice melt is at its maximum. It is never recommended to visit glacial caves during summer for this very reason. The combination of ice melt and glacial motion can be unpredictable and dangerous. #icecave #glaciercave #svalbard #ice #climatechange
