FRISCO, Colo. - Snow that some residents described as dark as chocolate brown was reported across parts of Colorado Thursday, a result of a wind storm in northern Arizona that kicked up dust that fell with the snow overnight, officials said.

"It's pretty much statewide," said Ethan Greene, director of the Colorado Avalanche Information Center. "We've had reports from the San Juans, Winter Park ... all over."

Greene said it's not unusual to see plumes of reddish dust from the desert Southwest drop on the Rocky Mountains in the spring.

Exceptionally dry conditions in northern Arizona contributed to the dust, Greene said.
