and China during the latter half of March. Westerly winds
aloft transported the dust cloud across the Pacific Ocean
and over the western United States...depositing some of it
In 2009...a blizzard developed over the Northeast Plains of
Colorado. Most of the Urban Corridor was spared from the
blizzard...with the exception of eastern Adams and eastern

the Colorado Front Range. Snowfall amounts of 4 to 7
inches were common around the Boulder area with lesser
amounts elsewhere. Only 2.0 inches of snow fell at
Stapleton International Airport where north winds gusted

in the city.

semi-trailers on their sides along I-70 and I-76 east of
Denver. Peak north wind gusts included: 60 mph near
Bennett and Keenesburg...59 mph near Brighton...and 53 mph
at Denver International Airport. Over the Palmer Divide
south of Denver...the high winds combined with heavy snow
to produce blizzard conditions. Snowfall accumulations
ranged from 3 to 8 inches over eastern Douglas and western
Elbert counties. Snowfall totals included: 8 inches at
Sedalia...4 inches near Castle Rock...and 3.5 inches near
5-6 In 1939...3.0 inches of snow fell in downtown Denver. North
