Alaska's Short Summer.

A brief snapshot of summer: Flowers bloom and ice melts as Alaska enjoys its annual burst of warm weather

From stealthy lynx to dazzling flower blooms, these stunning images show Alaska's brief summer in all its glory.

Temperatures in the Arctic region have jumped from a normal 8C (46F) to a relatively balmy 16C (60F) in recent weeks.

Alaska only glimpses warm sunshine for four weeks each year, in late June and July.

The result is a sudden, beautiful burst of flowers appearing across the northernmost U.S. state.

Nature photographer Jon Cornforth, 39 ,from Seattle, was lucky enough to qualify for the holy grail of his field - rarely granted permission to travel independently to photograph in Alaska's Denali National Park.

He said: 'People are hardly ever allowed to travel in Denali by themselves in their own vehicle - not even local people. And because of the short season I had to make the most of the opportunity.

'In Alaska they joke that June is spring, July is summer and August is fall or autumn as you call it in the UK.

'Every other month is bitter winter. This means that for animals and plants everything happens together.

'Spring is the time when the ice melts. Flowers bloom in the height of summer and once this happens it's pretty much fall.'

Mr Cornforth travelled over 3,000miles by land and sea to provide a unique snapshot of the environmental changes in this largely untouched wilderness.

As well as Denali Park, he visited haunting Heather Island and the coast of Prince William Sound.

He explained how his photos of a glacier dramatically crashing into the Atlantic Ocean are a precious record for future generations.

'My picture of the glacier crashing into the sea will not be possible from this location in the years to come,' he said.

'It's one of nature's most spectacular sights and a privilege to be able to witness first hand.

'Eventually the glacier will recede into the land and in years to come these pictures may be all that's left.'
