This is a sunrise photo of Lake Crescent in the Olympic National Park in the state of Washington. The lake is noted for it's crystal clear waters which result from a lack of nitrogen in the lake waters. The lake was formed during the last ice age from a combination of glacial carving and massive avalanches.
Lake Crescent is the second deepest lake in the state with an official depth of 635ft but is rumored to be over 1,000ft (300m) in depth. The shot was basically a set up and wait, bracket and select.
