A group of photographers captured a rare display of northern lights over Crater Lake in Oregon.
The stunning photos show the aurora borealis dancing over the lake's clear blue waters and snow-covered mountains.
The northern lights are caused by charged particles from the sun colliding with atoms in the Earth's atmosphere.
Crater Lake is a popular destination for photographers due to its clear waters and stunning scenery.
The lake was formed over 7,000 years ago when a volcano collapsed and filled with water.
The northern lights are a rare sight in Oregon, but can sometimes be seen in the state's northern regions.
The photographers used long exposure techniques to capture the beauty of the aurora borealis over Crater Lake.
