Parker Colorado Lake, a lake in Boulder County, Colorado, is known for its many colorful waterfalls.
But on Friday, an unusual series of pictures popped up in the water.
The lake’s most popular spring, Lake Parker, washes away on Sunday.
The pictures are a set of five photos taken between March 10 and April 16.
It is located about 25 miles southeast of Boulder, Colo., near the city of Denver.
Lake Parker is the oldest lake in Colorado.
The lake was first drained in 1874.
It was the first lake to be officially designated a national park in 1966.
Parker Colorado is the second oldest lake on the Great Lakes.
Its age is disputed, but the lake’s age was estimated at 50 to 100 million years old.
