I had a blast hiking to and photographing a pair of Ice Caves today. The whole trek ended up being about 8 hours long, with 8km (5 miles) roundtrip of hiking on a glacier. The journey was definitely worth it to witness and photograph these incredible caves. I lugged almost all my gear with me but ended up shooting with just one lens, go figure.
