Chinook Pass, near the entrance to Mount Rainier, was scheduled to reopen at noon today, the earliest opening in 23 years.
A combination of warm weather, a below normal snow pack and new snow removal equipment led to the early opening.
The pass has been closed since December 17 near the Mount Rainier National Park boundary.
The state Department of Transportation used global position station (GPS) technology to make it faster to find the exact spot to begin the snow removal process, speeding up the opening of the pass this year.
Today is the earliest opening since 1981. The earliest opening was April 5, 1973; the latest was just a year later, July 12, 1974.
