Clean-up volunteers gathered at the Four Peaks area off Highway 87 Saturday to help pick up garbage from the lower trails.
According to organizer Tim Huber, about 500 people showed up to help fill dumpsters and a dump truck full of trash left on the lower trails.
He estimates they collected about 20 tons of trash.
A blog website promoting the clean-up event said groups removed from the area trash including shotgun shells, TVs and computers, but volunteers also found a bowling pin, two mannequins and even a burned out piano.
Workers were treated to a lunch of hot dogs and several lucky volunteers won items donated to a raffle drawing.
The event ran from 9 a.m. to about 3 p.m. said Huber.
