Oregon Caves Needs Lint Pickers Sept. 26

Date: September 12, 2009

Stalactites, stalagmites and… lint?? It’s true! Approximately 50,000 visitors to the cave a year leave behind tiny bits of clothing fiber, hair and trash. Over time, lint builds up and can disturb the cave ecosystem.

On Saturday, September 26 Oregon Caves National Monument will host its third annual National Public Lands Day cave cleanup. Volunteers are invited to join park staff for a day of removing lint and trash from the cave with brushes, tweezers and other tools.

This event is a great opportunity to meet other volunteers and provide a real service to Oregon Caves. Volunteers will be rewarded with a pass good for one day of free admission to any fee site on public lands. Lunch will be provided and there will be an option for an off-trail caving trip in the evening.

Advance registration is required. To register, or for more information, contact Elizabeth Hale by e-mail (elizabeth_hale@nps.gov) or phone (541) 592-2100 ext. 2254. 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.

Please help us make America's Best Idea even better. Join us for a national day of service and celebration in your 391 national parks.

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.
