Bavarian photographer Christoph Jorda squeezed through a low entrance of the Pitztal Glacier in Tyrol, Austria to capture what’s inside—a stunning, frozen wonderland.

Despite the glacier’s close proximity to a popular ski resort, the entrance to the ice cave is located in the middle of a huge crevice, making it difficult to find.

“It was absolutely amazing in the caves, you feel the different temperatures and see different textures,” said Jorda. “But it’s also kind of scary knowing that you are 300 m (984 ft) inside an ice cave with 30 m (98 ft) of thick ice above you.”

Jorda ventured to the icy wonderland with friends Liz Kristoferitsch, Florian Hinterlang and his twin brother Matthias Jorda. Inside, the group discovered a lake and tall icicles hanging from the cave roof.

March temperatures in Tyrol range between 32 and 52 degrees F, with the valleys seeing signs of spring before the snow-covered mountains do. In the winters, as expected for a popular ski area, temperatures can fall down to 20 degrees F.
