Scotland experienced a cold summer this year and the result is the remaining snow and ice formed tunnels and caves connected to the Highland mountains. The UK Daily Mail quotes experts as saying a peculiar mixture of events has resulted in a beautiful array of snow tunnels, caves and even bridges that are at heights greater than double-decker buses.

The magnificent arrangements result from water flowing underneath snow and ice as it begins to melt. As the water moves underneath the snow and ice, a channel of air forms melting the snow from under it. The result is a vast network of glacier caverns that are large enough for people to walk in and the caves are adorned with uneven wave patterns.

This natural phenomenon was also reported in Scotland back around this time last year when similar ice and snow tunnel formations by the hundreds were discovered. This anomaly makes sense since planetary warming is at a standstill and, consequently, the formations reported this and last year are larger and deeper than have been previously recorded. One blogger, Eric Worrall, reveals that these glaciers maybe the beginnings of an ice age:

This is how ice ages start – a buildup of snow which does not melt in the Summer, which leads to a positive feedback loop, as the growing ice sheet reflects more and more sunlight back into space.
