Travels to the Oregon deep

We're looking out on the deepest lake in the US. Crater Lake, the centrepiece and namesake of the only national park in the state of Oregon, goes down to depths of 1,943 feet. Fed mainly by snowfall, this pristine, crystal blue lake came into this world with a bang. Sometime around 5700 BCE, Mount Mazama erupted, losing roughly 3,000 feet of its height. The volcano blew out so much molten rock that it left a giant depression that gradually filled with water, giving us this serene scene today.
