Spend the day underground providing a real service to the cave! Registration is open for the fourth annual National Public Lands Day cave cleanup at Oregon Caves National Monument. We are looking for volunteers to join us on Saturday, September 25 to remove lint and other small debris from the cave. This all-day event includes lunch and the option to go on an evening off-trail caving trip. Participants will be rewarded with a pass good for one day of free admission to any fee site on public lands.

Picking lint is a unique experience. Volunteer lint pickers at Oregon Caves were recently featured in an episode of Oregon Field Guide, available to watch online at www.opb.org. The buildup of lint in Oregon Caves comes from the clothes of approximately 50,000 visitors a year. Lint has ecological impacts in the cave and also degrades cave formations. Lint pickers use tweezers, brushes, and other tools to restore cave walls and clean trail surfaces.

Advance registration is required. Orientation begins at 9:30 AM at the Oregon Caves Visitor Center. To register, contact Elizabeth Hale at 541-592-2100 extension 2254, or by e-mail at Elizabeth_Hale@nps.gov. Anyone interested in volunteering but unable to attend this event is encouraged to call or e-mail to be put on a mailing list for future volunteer opportunities.

Did You Know?


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.
