“Lofoten Glow”. I was desperately searching a good sunrise spot this particular morning. Normally Storvatnet Lake is completely covered in snow, so you can only imagine my surprise when I saw these crazy ice formations almost being shot out of the frozen lake. I put my crampons on and took a big risk walking out. I could hear the ice cracking underneath my feet, and when you’re all alone in a fjord/canyon like this – the cracks are echoed and sound really frightening. Was it worth it? I sure think so! Photo location: Storvatnet, Lofoten Islands in Northern Norway. (Photo and caption by Stian Klo/National Geographic Photo Contest)

The National Geographic Photo Ark is a travelling exhibition of photographer Joel Sartore’s quest to create a photo archive of biodiversity around the world. So far, Sartore has captured studio portraits of more than 6,000 species – a number that he hopes to double. On 1 July, the ark will open at Melbourne zoo – the first time it has been exhibited in the southern hemisphere. More than 50 portraits will be on display, including many of Australian endangered animals being protected by programs at the zoo itself. These captions have been edited from text supplied by Melbourne zoo. Here: Barking owl. (Photo by Joel Sartore/National Geographic Photo Ark/The Guardian)

“We take rusty old junk and we put love into it”. The old Motor City has a unique style in bicycles these days: from fat wheels and fake fuel tanks to stretched cycles with powerful sound systems – and even a family-sized BBQ. “Detroit’s custom bike scene developed alongside Slow Roll, a weekly cycle ride started in 2010 by Jason Hall and Mike MacKool. Now upwards of 2,000 people turn up each Monday to cruise a different part of the city. The week I go the crowd seems evenly split between black and white, male and female, city and suburbs. It’s the most inclusive cycle event I’ve ever witnessed”. (Photo by Jason Walker/Slow Roll Monday Nights)
