The Monongahela National Forest has extended its cave closure order indefinitely. Here's a link to the announcement:

The order says it will remain in place until a cave management plan is developed, or new WNS info "pursuades" changing the order.
Seems the NSS/VAR should step up to assist in developing the cave management plan as soon as possible.
