No experience is necessary to participate, just a desire to restore the cave and ability to perform light physical work. Advance registration is required, as these events can fill up.

Did You Know?

Scorpion under ultraviolet-DYK

Scorpions fluoresce or glow under ultraviolet (UV) black light. They can glow electric green or blue. Scorpions fluoresce because they contain a fluorescent protein in the upper layer of their exoskeleton. This layer is like your fingernail, but even more protective and tough. The special protein inside is thought by scientists to serve as an ultraviolet sensitivity mechanism, perhaps allowing the scorpion to avoid burning itself by staying exposed too long to damaging light levels.
