Emergency Contacts
Call 911 in a cave emergency.
A few years ago Eastern Region, NCRC decided that it is best for cavers with an emergency to call 911 or the local emergency number if it is not 911. The 911 call centers should be up-to-date on who to call if there is a cave emergency. however, since this is not the case for all of the areas we cave in, Here’s a short list of cave rescue contact numbers:
- Eastern Region NCRC (VA,WV,PA,NC,MD,DE,NJ) 911
- Northeast Region NCRC (NY,MA,CT,VT,NH,ME,RI) 914-964-2424
- Tennessee: 800-262-3300 (in state), or 800-258-3300

FAQ
Who are we?
We are a group of individuals from the Philadelphia area who like to drive 14 hours (sometimes less) to crawl around and get wet and muddy in caves. Many grotto members are active in other outdoors activities, such as backpacking, white water rafting, hiking, sailing, rock climbing, and mountaineering.
The Philly Grotto emphasizes the National Speleological Society motto:
Leave nothing but footprints, take nothing but pictures, kill nothing but time.
We are a conservation-minded organization interested in educating people about the underground wilderness that we love.
Why do we do this?
Few of us actually know this answer. It’s probably a combination of a spirit of exploration, natural beauty, friendship and physical challenge.
How do I get involved?
Come to a meeting, join the grotto and sign up for a beginners trip.
How do I get more information about joining?
Come to a meeting and we’ll answer all your questions. If you can’t make a meeting, email the grotto membership chairperson
