Did some searching through some old threads, here's what I found. Most (if not all) of this info came from Bill:
Deep Step (including lollipop): 500' Deep Step Connector (going to Deep Step Rd): 100' *Deep Step Rd. to high point of Tower: 450' Big Rock & Tower: 800' Great Wall & Connector to Parking Lot: 580' Skinny: 320' Brown Wave (including lollipop): 300'
*Some of this is getting counted twice....
So that's a total of about 2,950'
Maybe someone will have an altimeter w/them this weekend and ride all six loops and post it on MotionBased.
