Anne and I exploring one of the ice tunnels together (how did Moritz end up in the background on this photo too??). You can really see the blue ice clearly in this one. Our guides told us that we were incredibly lucky to get ice caves and tunnels like the ones we were able to experience, because it is rare that they will form in the ice fall part of the glacier, where we were exploring. Normally, because of the intricacies of glacial formation, ice caves and tunnels like this form up in the neve (snow fall area), where you have to take a helicopter to reach.
