Alaska

Despite its norther location, with low temperatures and thus reduced chemical activity, there are numerous big caves in Alaska. The reason are the high precipitation and the acidic soils of the typical west coast rain forests. Wherever soluble rock like limestone and marble occurs, intense karstification is found too. The most impressive karst areas are located in southeast Alaska, especially in Tongass National Forest on Prince of Wales Island. El Cap Pit is at the moment the deepest single drop pit in the USA.
