It's not something for the faint of heart. On Saturday Taylor VanAllen crossed Eldorado Canyon on a slackline.

VanAllen, 25, walked about 500 feet across the canyon on the inch line about 450 feet above the canyon floor.

It hasn't been done since 1948, when the canyon was crossed by an 82-year-old guy named Ivy Baldwin. He didn't have a net, or a safety attachment.

On Saturday, VanAllen, who's from Morrison, had a safety leash. He didn't need it for the hour long journey.
