167.33(3)(h) (h) Lifts; signs required. For each lift that is used by individuals engaged in skiing and that does not serve any trail that is described under par. (f) as "easier," the ski operator shall post and maintain, at or near the loading area for the lift a sign that is at least 10 square feet in size near or at the entrance of the loading area. The sign shall contain the following warning:

"WARNING: This lift does not serve any trails that are "easier" (marked with a green circle emblem). All of the trails served by this lift are "difficult" or "more difficult" (marked with a blue square emblem), "most difficult" (marked with a black diamond emblem), "expert" or "extreme terrain" (marked with an emblem consisting of 2 black diamonds), or "freestyling terrain ahead" (marked with an orange oval)."

167.33(3)(j)1.1. In lieu of posting and maintaining each of the separate signs required under par. (b) and par. (d) or (e), a ski area operator may post and maintain a single sign that is at least 12 square feet in size and that contains all of the required warnings.

167.33(3)(j)2. 2. A ski area operator may, in a ski area with fewer than 100 acres in use for a snow sport vary from the specific wording, size, and location requirements for signs specified under this subsection, but any variation may not preclude a reasonably prudent participant in a snow sport from finding or understanding the contents of the sign.

167.33(4)(a)(a) Maps. Each ski area operator shall post and maintain a map of the trails and terrains in the ski area that are designated for any snow sport at all of the sites where tickets to the ski area are sold if the ski area has more than 3 trails.

Each ski area operator shall mark hydrants, water pipes, and any other man-made structures on a ski area that are not readily visible to participants in a snow sport under conditions of ordinary visibility from a distance of at least 100 feet. A ski area operator may use any type of marker, including a wooden or bamboo pole, flag, or sign if the marker is visible from a distance of 100 feet and if the marker itself does not constitute a serious hazard to participants in a snow sport. Variations in steepness or terrain, whether natural or as a result of slope design, snowmaking, or grooming operations, including roads, catwalks, or other terrain modifications, are not man-made structures for the purpose of this paragraph.

167.33(4)(ar) (ar) Padding policies. A ski area operator shall adopt a written policy determining which man-made ski area infrastructures require protective padding and determining the type, height, thickness, and color of the padding.

167.33(4)(b)2. 2. If any grooming operations take place on a ski trail during hours in which a lift is being operated, the ski area operator shall close that trail to the public at the top entrance to the trail until the grooming operations are complete on that trail. If a groomer is traversing part of a ski area that is not part of a ski trail during hours in which a lift is being operated, the ski area operator shall provide an escort for the groomer to warn guests of the approaching groomer.
