In about six hours, the hillside that looked out over the Front Range was completely transformed. The grass and rocks were moved away, and a new trail was put in their place.

On Saturday, more than 70 volunteers descended on Floyd Hill Open Space to build a half mile of new trail running up the ridge from the meadow.

“I’m amazed over the years at how much work (volunteers) can get done in a day,” said George Rasmussen, one of Saturday’s volunteers. “… We are creating a trail that will be used for decades.”
