Parts of Colorado and Wyoming were engulfed in a record-setting
blizzard between March 18 and 19, 2003. The Rocky Mountains were
hammered with as much as 87 inches (7.25 feet) of snow in places, and
Denver received about 30 inches, which shut down the airport and
stranded motorists. Several people lost their lives in snow-related
accidents, and more than one hundred roofs collapsed in Denver from the
weight of the heavy, wet snow. Avalanche danger skyrocketed, and an
avalanche blocked the road to a mountain ski resort, forcing guests and
employees to sleep overnight on floors. The danger was too high for
them to venture out onto the slopes.
