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.

Pileated Woodpecker

The Pileated Woodpecker is the largest North American woodpecker. Funny, mischief making cartoon character Woody Woodpecker, was inspired by this bird. Other birds need this species for survival. They will use the holes or cavities the Pileated drills as nests, winter shelter, and a way to get at food inside trees that is otherwise hidden.
