Incredible ice caves inside Iceland glaciers
Mother nature is showing off for photographers taking these impressive photos inside the crystal caves in Iceland's Vatnajokull glacier.
When the sun rises or sets outside or if you start a fire inside the cave the light reflects off the ice resembling a frozen waterfall.
In the fall, sightseeing groups start scouting the crystal caves since their formation relies heavily on the weather.
Once it's cold enough and the ice is sturdy enough -- tour guides can take people through the blue, glass-like caverns.
