I figure maybe someone should actually drop a bit of nawlege on this post:
Colorado Skier Safety Act
33-44-109. Duties of skiers - penalties.
(1) Each skier solely has the responsibility for knowing the range of his own ability to negotiate any ski slope or trail and to ski within the limits of such ability. Each skier expressly accepts and assumes the risk of and all legal responsibility for any injury to person or property resulting from any of the inherent dangers and risks of skiing; except that a skier is not precluded under this article from suing another skier for any injury to person or property resulting from such other skier's acts or omissions
any provision of law or statute to the contrary, the risk of a skier/skier collision is neither an inherent risk nor a risk assumed by a skier in an action by one skier against another.
(2) Each skier has the duty to maintain control of his speed and course at all times when skiing and to maintain a proper lookout so as to be able to avoid other skiers and objects. However, the primary duty shall be on the person skiing downhill to avoid collision with any person or objects below him.
(3) No skier shall ski on a ski slope or trail that has been posted as "Closed"
Before beginning to ski from a stationary position or before entering a ski slope or trail from the side, the skier shall have the duty of avoiding moving skiers already on the ski slope or trail.
(10) No skier involved in a collision with another skier or person in which an injury results shall leave the vicinity of the collision before giving his or her name and current address to an employee of the ski area operator or a member of the ski patrol,
except for the purpose of securing aid for a person injured in the collision; in which event the person so leaving the scene of the collision shall give his or her name and current address as required by this subsection (10) after securing such aid.
(11) No person shall knowingly enter upon public or private lands from an adjoining ski area when such land has been closed by its owner and so posted by the owner or by the ski area operator pursuant
to section 33-44-107 (6).
(12) Any person who violates any of the provisions of subsection (3), (9), (10), or (11) of this section is guilty of a class 2 petty offense and, upon conviction thereof, shall be punished by a fine of not more than one thousand dollars.
Or the short version: You are responsible for anyone down hill of you. If you hit them, they can sue you. If you hit them, then run, they can still sue you and the State of CO will tack on a criminal offense and $1000. Cutting 'Closed' ropes, skiing while drinking and cutting out of the ski resort not through a back country gate can earn you a criminal offense and $1000 fine.
On occasion, I've seen someone out-run a patroller. But I've never seen them out-run his radio to the bottom... food for thought.
Safe turns and deep pow everyone
