Join us for one of our annual volunteer events when we provide a real service to Oregon Caves by picking lint and bits of trash along the cave tour path! 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?

Debugged-DYK

Computer bugs, slang for something gone wrong in a program, are actually named for a real insect. In 1947, technicians working for computer scientist Grace Hopper found a moth inside her computer. The trapped moth was making the machine malfunction. Once removed, they reported that the computer was “debugged”. They taped it onto her notes with a little joke that is now part of our everyday language.
