With towering, crystalline halls of frozen water, ice caves are among the most visually arresting formations in nature. They're just a pain to explore given their often inaccessible locations and the inhospitable climate that allows for their development. But that's where the drones come in.

With the assistance of a GoPro HERO3+ Black Edition on the DSLR Pros DJI Phantom, Firefight Films has produced a stunning look at some of Alaska's coolest ice caves. What's more this is reportedly the first time a UAV has been used to capture such footage. Though, with the recent NTSB ruling in favor of commercial drone flights, mind-blowing reels like this could soon become much more prevalent.
