Exploring Caves: Journeys into the Earth Nancy Holler Aulenbach
Readers share the adventures of two women cavers - a teacher and a microbiologist - as they explore ice caves in Greenland, underwater caves in Mexico's Yucatan Peninsula, and terrestrial caves in the southeastern United States. Their exploits form the basis for MacGillivray Freeman's large format film Journey Into Amazing Caves, which will be shown in IMAX theaters beginning in March 2001.
