If a guest is under 18 years of age a parent/guardian must complete a waiver on his/her behalf. Waivers remain on file for 1 year from the date they are signed. If you come back within a year, you do not need to complete the waiver again, we can look it up for you! The only exception to this is if you turn 18 within the year. Once a climber turns 18, they will need to sign their own waiver.
