These stunning images show intrepid cyclists biking over snow and ice along a giant glacier.
Photographer David Canales, 31, took a special fat-tyre bike to explore Knik Glacier, last month. After hearing of the fast-growing sport that uses bikes with five inch wheels, he set off with pals for the COOL adventure.

The outdoor enthusiast rode over frozen lakes, between icebergs and through snow to reach the titanic glacier.
He said: "We rode 10 miles to the glacier face, then the face itself is 10 to 20 miles, we rode along side it.
"When we were there looking at the views, we just had this feeling of 'is this real' - it's just so immense. These huge mountains towering over us, you just feel so small.

"It's incredible to be able to go right up to the glacier and touch it – which you can't do unless you're on foot and there's so many ice caves to explore.
"You just feel really tiny. We spent the whole day exploring and just lost track of time."

It took the team 10 hours there and back, going at between 5- 10 miles an hour, depending on the snow quality.
He said: "Fat biking is really growing in Alaska. "I just recently purchased a fat bike, so I just went for it. We had to get the timing right, there was just a small window in spring, before it's too warm and the river melts.

"Luckily everything was good, there were no dangers. "Social media is a great way to work out what the conditions are like.
"It had warmed up on the way back which slowed us down and we had to deflate our tyres to make it easier."

Born in bred in Texas, David had little knowledge of glaciers until he moved to Alaska in 2011.
He added: "I moved out for an adventure, I like to get out somewhere every weekend.

"It's amazing what's out here."
