Description:
Find a hollow or natural passage under or into the earth and mark the entrance or opening. Please be aware that cave exploring is an inherently dangerous activity that, like rock climbing, is made safer by the use of proper equipment and knowledge. To learn more about responsible, safe, and environmentally friendly caving, this group encourages you to seek out a local cavers' club for a good introduction to the sport.
