Sunshine's Delirium Dive opens as weather and conditions allow. Conditions this year finally worked to allow the ski patrol to open the 600-acre experts-only terrain Mar. 1. The freeride zone features steeps with an average pitch of 40 degrees and areas exceeding 50 degrees. The inbounds, patrolled terrain is accessed by a five-minute climb from the top of the Continental Divide Express. Skiers and boarders must be equipped with an avalanche transceiver, shovel, and a similarly equipped partner to pass through the control gate that only opens with working avalanche transceivers. Natural hazards are not marked. Most skiers and riders drop into the Dive with someone with previous experience with the terrain. Sunshine Village's Ski and Snowboard School navigates newcomers through the difficult terrain in their Delirium Sundays program.
