Blanca Lake and Columbia Glacier, Washington, USA from the air

This was definitely the hardest journey on foot I've taken to get a drone flight location- I ended up traveling between 12 and 13 miles with about a 4,000 foot elevation gain. In addition to the drone and control equipment, five Phantom 3 batteries never felt heavier! Because of the bright sunlight, an ND32 filter was used throughout and I still had shutter speed up at 1/80, which is a little higher than I like. That was to keep from blowing out the highlights, especially the Columbia Glacier. Blanca Lake is a glacial fed lake, which gives its blue-green color. The term for this is a "rock flour lake".
