Purchase a Columbia Grind™ Timer Card, containing a radio frequency chip, from Grouse Mountain (or use your existing Grouse Mountain Summit Seeker Card). Swipe your card at the Timer at the base of the Grouse Grind®, and again at the top of the trail, and your name and time will appear on the monitor at Alpine Guest Services in the Peak Chalet. Your results may also be printed for you at Alpine Guest Services.
