Picture of explorers in an ice cave under Mount St. Helens

"A team of scientists, cave surveyors and photographers explores a previously unentered glacier cave within crater of Mt. St. Helens," explains Your Shot photographer Eric Guth. "Mapped, surveyed and explored for the first time in June of 2014, the team mapped nearly a mile of previously unexplored passages and galleries, standing in awe, at this moment, at the beauty they had discovered lying just beneath the surface of the only advancing glacier in the low 48 states, Crater Glacier."
