The Annual Emptying of Lake George, Alaska
Description and partial interpretation of the natural emptying of this ice-dammed lake in south-central Alaska. Regional and site characteristics, the 1951 observations and other emptyings since 1935 are described; and the age of the lake as evidenced by terracettes, willows, alders, and exposed del...
