Ice caving? Is there such a thing? Exploring ice caves?
Yes, there are caves/caving/cavers in Alaska, although no active grottos/clubs right now. Most caves here require significant effort to access, like traveling by aircraft/boat/foot etc into remote locations. There is major limestone karst on Prince of Wales Island in southeast Alaska, and also on other islands in that region. Also some pockets of favorable karst in other parts of the state, although most of the geology in southcentral and the interior doesn't lend itself to major cave systems.
Yes, there is such a thing as ice caving - though the term is often misunderstood. An ice cave is a cave formed in rock that contains perennial ice. You may be thinking of glacier caves, which are caves formed in ice, often melting and reforming each year. Alaska does have glacier caves.
