Aerial view of Gilkey Glacier, #Alaska The Gilkey Glacier is one of the 38 glaciers whose source is the Juneau Icefield. Bow-shaped structures known as 'ogives' appear at the foot of a steep slope. In summer, higher temperatures force the ice to creep downhill at a slightly faster speed than during the winter months. Suddenly the flow rate slows as the terrain levels out and the cold mass becomes compressed into thick humps. In the winter, when the ice tongue moves forwards more slowly, less ice becomes compressed causing the constrictions between the humps. The ogives of the Gilkey Glacier are bounded by two moraines, with a melt water stream flowing down the middle.

I Love You: 3000
From sunset to moonset, 15hrs apart but such a wide range of colors, scenes and life. I love sunsets, moon rises and sets during the winter in Northern latitudes. When the weather allows it (not cloudy or snowing) the low temperature, reduces the humidity in the air and allows for brighter, clearer view of the sun and the moon. For this February’s full moon, I made two session, one right before sunset and a second one during the moonset. I was lucky enough to have a perfectly clear sky and temperatures between -8degC and -4degC (17.5degF and 25degF) to get these photos.
