At about 1130 Mountain time the airplane collided with terrain during an attempted landing. The airline transport pilot and sole occupant was not injured; the airplane sustained substantial damage. Visual conditions prevailed. According to the pilot, who was familiar with the airport, the runway was covered with two or three inches of snow and he could not easily discern its centerline. When he touched down, one of the airplanes main gear was not on the runway surface and impacted a snow-covered mound of previously plowed snow. That impact threw the airplane sideways and it collided with more previously plowed snow. All three landing gear struts collapsed and the airplanes belly sustained considerable structural damage.
