Crank out the jams

Pitkin County officials warned the public on Tuesday that an “ice jam release” on the Roaring Fork River — shown here Tuesday in Snowmass Canyon — is imminent. The natural phenomenon happens seasonally, when ice blockages come loose along the river during a mid-winter warm spell, unleashing a torrent of water and debris downstream. This poses a grave danger to anglers, or anyone else in the river, when the ice jam releases. County officials warn that the event could happen today, originating in Snowmass Canyon and affecting the river corridor to Carbondale. “These conditions are predicted to exist throughout the week, please be aware when in or near the river,” says a Tuesday afternoon Pitkin Alert message.
