Mount Washington’s Iceberg

Of course one of the most fascinating things about this picture is the layers of ice and their different colors. Water is a fascinating substance by how the properties of freezing change according to temperatures. When water freezes near 32F/0C, it takes on a whitish color due to the crystalline structure of the ice. Towards the bottom of the ice it is clear like glass. This occurs when water freezes well below the freezing level and the crystalline structure is very organized. We can actually use these layers to help identify when in time they froze. During the early part of winter, Mount Washington was very cold with several weeks at or below zero. Having that knowledge we can then determine that the ice clear block occurred during that time and then each layer afterward could be connected to an event.
