Trial Biking
Cold and creeping – these images display the world’s most impressive glacial landscapes.
They've been in existence for epochs, yet change everyday – they're stolid and immobile, yet constantly moving. Alpline glaciers are rivers of ice coming down from a mountain. Their movement is as undeniable as gravity itself – and so is their magnifence. Scroll down for some of our favourite icy images.
Black and white
Adventure photographer Jody MacDonald nabbed this shot high above the Knik Glaciers in Alaska while scouting a paragliding trip.
Flying over Mordor
Who said islands can't have glaciers? A speed rider swoops in front of a glacial cliff on Mt Cook in New Zealand.
Glacial gap
David Lama gaps across the glacier on a slackline while waiting in base camp during his attempt on Masherbrum this spring.
Icy biking
Petr Kraus rolls on in Greenland. How many glaciers are there in a place called Greenland, you might wonder? 54. Not very green.
Risky walking
Axel Naglich and Peter Ressmann move carefully across Mount St. Elias, the second-highest mountain in the North American continent. The original goal was to summit, then descend via a 5,000m+ run to Icy Bay, Alaska.
Across the ice

Canvassing for caves
Cave explorer Robbie Shone searches for 'moulins' – holes that open to glacial caves – on the Mt Blanc Massif.
Ice boat
The Jacobsen Glacier flows from the Holland Range in Antarctica, north-east into the Ross Ice Shelf. Safe to say, it's always cold down there.
Foxy and freezing
New Zealand's Fox Glacier is jagged, intimidating, and tough to tackle. Danger awaits those who come near.
Sea of glass
The 'Mer de Glace' descends from the Mt Blanc Massif in France. Ridges in the ice show the slow movement, having taken place over decades and centuries.
Glacial ponds
Below Mt Blanc, glacial pools collect cool blue water. Even if you fancy a dip, probably best to wait until you're in the valley before getting wet – that water was probably ice not too long ago!
Canyons and crevasses
A team of climbers moves carefully over various pitfalls and dangers – always a standard of glacial exploration.
Fogged in
The Von Post Glacier in Spitsbergen, the largest island of the Arctic archipelago Svalbard – one of the world's most incredible adventure destinations.
Serene Serrano
The Serrano Glacier in Chile enjoys a rare moment of sunshine and calm weather.
Glacial over under
The vast majority of this particular glaciar sits below the water level – in this case, over 90 percent of it.
