Lake Silencio
From Tardis Wiki, the free Doctor Who reference
Lake Silencio was located in Utah. On 22nd April, 2011, the Doctor, Amy Pond, River Song, and Rory Williams picnicked there. During the picnic a figure in a vintage space suit from the Apollo program emerged from the lake and shot the Doctor, killing him. His body was placed in a burning boat and pushed into the water.
