Though the whole southern half of Rim Drive was closed due to lingering snow (571" last winter -- that's 48 FEET) and winter damage, the ideal
70-degree weather produced dazzling photos of this 6-mile wide volcanic caldera that is the 2nd deepest lake in the USA, with a maximum depth
of 1943 feet. It is all snow melt and rain, as there are no inflow or outflow channels. It is pure and clean, and oh-so-bluuuuuuuuuuue. [46 photos]
