A winter that never seems to end is foiling Fourth of July holiday plans for people in many Western states.Ski poles are replacing fishing poles as many popular hiking and camping destinations have yet to defrost after late-winter snowstorms that blanketed mountains from the Rockies to the Sierra Nevada.At lower elevations, the spring thaw has led to surging waterways, turning normally easy crossings perilous and raising flood concerns.The prospect of dense snow and mild temperatures is great news for snow-sport enthusiasts. Several popular Western ski resorts will reopen for Independence Day — some for the first time in more than a decade.But campers and hikers are less enthusiastic. Many have canceled or modified trips to avoid snowy trails, high water on roads and slippery mud.
