Spelunking
The challenges of the sport depend on the
cave being visited, but often include the
negotiation of pitches, squeezes, and water.
Climbing or crawling is often necessary, and
ropes are used extensively for safety of the
negotiation of particularly steep or
slippery passages.
Caving is often undertaken for the enjoyment
of the activity or for physical exercise, as
well as original exploration, similar to
mountaineering or diving. Physical or
biological science is also an important goal
for some cavers. Virgin cave systems
comprise some of the last unexplored regions
on Earth and much effort is put into trying
to locate and enter them. In well-explored
regions , the most accessible caves have
already been explored, and gaining access to
new caves often requires digging or diving.
Caves have been explored out of necessity,
out of curiosity or for mystical reasons for
thousands of years. However, only in the
last century or two has the activity
developed into a sophisticated, athletic
pastime. In recent decades caving has
changed considerably due to the availability
of modern protective wear and equipment. It
has recently come to be known as an "extreme
sport" by some.
