Cave Diving Group

The Cave Diving Group (CDG) is a United Kingdom-based diver training organisation specialising in cave diving.

The CDG was founded in 1946 by Graham Balcombe, making it the world's oldest continuing diving club. Graham Balcombe and Jack Sheppard pioneered cave diving in the late 1930s, notably at Wookey Hole in Somerset.

Passages through caves are often blocked by a submerged section, or sump. Cavers in many countries have tried to pass these barriers in a variety of ways; using the simple "free dive" with a lungful of air or by utilising the available diving technology of the day.

Famous quotes containing the words group, cave and/or diving:

    Now, honestly: if a large group of ... demonstrators blocked the entrances to St. Patrick’s Cathedral every Sunday for years, making it impossible for worshipers to get inside the church without someone escorting them through screaming crowds, wouldn’t some judge rule that those protesters could keep protesting, but behind police lines and out of the doorways?
    Anna Quindlen (b. 1953)

    What difference is there, do you think, between those in Plato’s cave who can only marvel at the shadows and images of various objects, provided they are content and don’t know what they miss, and the philosopher who has emerged from the cave and sees the real things?
    Desiderius Erasmus (c. 1466–1536)

    A worm is as good a traveler as a grasshopper or a cricket, and a much wiser settler. With all their activity these do not hop away from drought nor forward to summer. We do not avoid evil by fleeing before it, but by rising above or diving below its plane; as the worm escapes drought and frost by boring a few inches deeper.
    Henry David Thoreau (1817–1862)
