French Cave Explorer Tells Underground Stories Today

Internationally known cave-explorer Pierre Ageron will discuss French cave explorations tonight at the Biological Laboratories. The talk, which is being sponsored by the Boston Chapter of the American Speleological Society, will be given at 8 p.m. in Room 115.

Ageron, who is vice president of the Societe Speleologique de France, is visiting this country for a short time.

Ageron runs a commercial cave in Ardeche. "L'aven-Grotte Marsel," famous for its spectacular formations, is one of France's most interesting caves. Ageron reopened the entrance, which had been closed since 1394, three years ago.
