These fascinating images are the result of a photographer using LED lights to track his climbing routes up sheer rock faces and mountain hikes.

27-year-old Luke Rasmussen takes to sky-high ridges across the USA under the cover of darkness so he can use the lights to turn his journeys into colorful patterns.

He records the routes through a series of long-exposure images taken from the foot of each rock face.

"I wanted to capture the passage of time as I moved up a rock face, flowing from one hold to the next," says Rasmussen. "I wanted a way to visualize the line that exists in a climber's mind as he pieces together the natural features of the wall.

"I wanted to be able to illuminate the motion that I experience while climbing. And I think I've begun to do just that.

Rasmussen, who is from Las Vegas, started rock climbing at the age of 11 before he even got his hands on his very first camera.
