Russia’s Kamchatka Peninsula is a remote place by any measure, but it’s worth the trip to see an ice cave nearly a kilometer long that was created by water from a hot spring that flowed under a glacier. Reader Roberto Lopez of Asturias, Spain submitted these pictures from a recent trip. See more of Lopez’s photos at http://www.robertocarloslopez.com.
