A Statistical Theory of Cave Entrance Evolution
Rane L. Curl


The question of the number of caves that may exist in a region or a country is one that is often raised by both laymen and scientists. In the past many estimates ranging from mere guesses to those based on empirical deductions have been proposed. To these estimates is now added a statistical approach which gives a more substantial foundation to the postulated number of caves. Rane L. Curl was introduced to cave exploration during the summer of 1952 in Charleston, W. Va. While at the Massachusetts Institute of Technology as a graduate student he was chairman of the Boston Chapter of the National Speleological Society. At present Dr. Curl is on the research staff of Shell Devleopment Company in Emeryville, California.
