Matt Wilson, owner of Four Corners Whitewater, untapes windows of the newly repainted bus the business recently bought to be used this rafting season on the Animas River. The river peaked at 1,350 cubic feet per second Monday. A warm spring has led to an early start for rafters, Wilson said. A storm front is expected to cool things down in Southwest Colorado later this week. The National Weather Service predicts a chance of snow in Durango after midnight Thursday.
