The National Cave Rescue Commission ( NCRC ) received its charter from the National Speleological Society in 1979, and serves as the Society's representative on issues of cave rescue training and operations. It is a volunteer group developed primarily to train and track cave rescue resources throughout the United States. The NCRC is specifically NOT a functional cave rescue team, rather it provides training and development opportunities for persons and organizations engaged in cave rescue activities. Thus, while many of the persons associated with the NCRC perform rescues, they do this as members of their local rescue squads, civil defense units, or cave rescue groups. The NCRC is a component of the Department of the Administrative Vice-President of the National Speleological Society ( NSS ). The NCRC is affiliated with the Cave Rescue Section of the NSS which publishes a cave rescue newsletter called the "Muddy Litter Letter." For information on the Cave Rescue Section newsletter, send email to Lynn Ott at: EnviroFacility@aol.com The main focus of the NCRC is development and maintenance of a national curriculum in cave rescue operations. It maintains a cadre of qualified cave rescue instructors, who help it deliver cave rescue educational programs at the national and regional levels, in a variety of formats.
