A Wasilla man was seriously injured Monday evening when his motorcycle struck a moose on the Parks Highway, just over a week after another moose-motorcycle collision killed a Connecticut man.

Alaska State Troopers were informed of the Monday collision at 11:49 p.m. The incident occurred at Mile 122 of the Parks, where a Harley-Davidson motorcycle driven by 45-year-old Charles G. Moses had been headed south on the highway.

“Investigation revealed the motorcycle was traveling (a) little slower than the posted speed limit of 65 mph when a calf moose stepped onto the roadway in front of the motorcycle,” troopers wrote in a Tuesday dispatch. “The motorcycle hit the moose causing the driver to lose control. During the collision, the driver was thrown from the motorcycle onto the shoulder of the roadway.”

Moses was flown by air ambulance to Providence Alaska Medical Center in Anchorage. He was initially reported to be in critical but stable condition, but had improved Tuesday to serious condition.

Troopers say Moses was wearing a helmet during the crash. His motorcycle sustained several thousand dollars of damage.

In the earlier moose-motorcycle crash, 57-year-old Philip J. Dubuorg was pronounced dead at the scene July 15 when his Kawasaki motorcycle hit a moose on the Richardson Highway near Delta Junction. Troopers said he had been on a cross-country motorcycle trip.
