Description: The Tongass National Forest contains world-class karst features and the largest concentration of associated dissolved caves known in the state of Alaska. This paper describes the dominant karst formation processes operating in southeast Alaska, the controlling geologic and hydrologic characteristics, and the influence of karst landscapes on associated forest resources. Recent sediment deposits and waterline marks in underground karst drainage systems suggest that timber harvesting has increased sediment and debris transport and the flooding of certain underground passages.

Keywords: Karst, epikarst, caves, paleontology, Tongass, Alaska
