Ski patrollers miffed by wages they say are too low for high living costs have put a wrench in operations at the biggest U.S. ski resort with a rare strike that began over the busy holidays and carried on into the new year’s fresh powder.

Yet some skiers who paid good money for passes are sympathetic.
