When you spend hour traversing Britain's most picturesque peaks, you always want some kind of visual souvenir to commemorate your efforts.
And while most climbers opt for a standard panoramic image, bright spark Dan Arkle marked his journey with these spectacular light trails thanks to a head torch and some camera wizardry.
The intrepid 34-year-old scaled the Peak District on his own without ropes, capturing his exact route by using long exposure camera techniques to catch his every move.
Dan, from Sheffield, had to endure freezing cold temperatures as well as navigate course and treacherous rock only using minimal light available.
The stunning light trails show how traversed rugged terrain before scaling fearsome peaks and descending back to ground level again on his treacherous climbs.
The long exposure element of his photos also provides spectacular backdrops in the form of star trails across the night sky.
Dan prides himself on his ability to capture star trails within his amazing photographs.
He said: "The star trails in the sky are formed when the stars appear to move in the sky due to the earth spinning on its axis (just as the sun does).
"As the North Star (Polaris) is above the North Pole, it appears stationary and the other stars seem to move round it.
"Any exposure of longer than a few seconds will result in some star movement being captured.
While climbing a landmark known as Higgar Tor he had to climb the rock by painfully jamming his hands into cracks.
He said: "I got to the top of the first climb the rock was covered with ice.
"As I was climbing solo and ropeless, this gave me a few scary moments until I found a way round, the climbs are around 60 foot high.
"Climbing was strenuous and a little painful, but keeping my hands in the cracks also means that I felt secure.
"There was no danger of slipping off unexpectedly, but I knew I would have to get to the top before I got too tired or my hands got too cold."
