Geology

Geology can be a complex and confusing subject, even for trained geologists. As with many sciences, geology has a lot of befuddling lingo and jargon, but without some sort of guide with which to describe what we observe, interpretation is impossible. We hope you can use our website as a guide to learn more about Oregon Caves before or after you visit. Lets discover some of the "unusual scientific interest and importance" of the Oregon Caves.

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.
