Autumn has barely arrived in Oregon, and already snow has fallen at Crater Lake.

Park official Marsha McCabe says there was an unusually early snowfall Tuesday and Wednesday, with eight inches on the ground.

McCabe says September snowfall at the National Park is rare-usually a dusting of an inch or two.

But when things get going in the winter, the snowfall at Crater Lake averages more than 500 inches a year.

McCabe says the North Entrance to the part and West Rim Drive are temporarily closed, but should be reopened by the weekend as the forecast calls for nice weather.

California's first-in-the-nation mandate requiring fuel producers to reduce greenhouse gas emissions has been upheld by a federal court.

A three-judge panel of the 9th U. S. Circuit Court of Appeals yesterday rejected arguments from fuel makers that California's low carbon fuel standard discriminates against out-of-state producers.

The ruling reverses a U.S. District Court ruling in favor of the fuel makers, and removes an injunction halting implementation of the law.

Charred forests left behind by wildfires make the mountain snowpack melt faster, according to a new study.Western rivers depend on the snowpack.

Study author, OSU doctoral student Kelly Gleason, says they found more snow fell in burned forests than in green ones. But the snow melted off twice as fast in burned forests, and was gone 23 days earlier. The reason was the black bits sloughing off the charred trees onto the snow intensified the heat from the sun.

Eighty percent of forest fires are in the snow zone.
