FATMAP difficulty grade
Ontario Bowl is some of the only hike-to terrain at Deer Valley, and usually has some of the best snow in the entire resort. It is a short hike, and the run itself is fairly simple.
Off of Ontario, a little bit past Hidden treasure, there is a cat track marked Ontario Bowl.
Take a left onto the track and start hiking. After about 5 minutes, the cat track opens up.
At this point, take a right through the trees and ski the fall line back down to Ontario.
