Chads gap is literally across the parking lot from Alta. It's really not that hard to find. It's also big, and if you need to dig the cheese wedge plan on spending a day doing it. I know a couple of skiers that hit it. Very, very good (one is sponsored now) skiers. They all exploded on landing. Definitely cleared it but it's a hell of a jump. One you don't want to come up short on.
if you look closely at the shots you can figure out where it is pretty easily. If you weren't looking to commit the two or three days of man power required to build the in run and wedge it could make a cool step up or even a quarter pipe feature.(if there's enough snow) Also there is the smaller pyramid gap which is just down the canyon from chad's
