I'm sure geologically, you're correct, Harry. Some mountain ranges are more or less likely to feature pronounced "rock bands." Other features such as hidden scree fields, hidden ledges, etc. with poorly bonded snow present a silimar challenge, and resultant adrenaline shot. If there's some other pithy connotation here, the rest of us aren't sophisticated enough to catch it.
If you're not prepared to ski whatever conditions may be present, perhaps you need to stay where things are patrolled, insured, marked & "safe". Otherwise, there may be challenges that come upon you that the skier alone needs to deal with. Depending on where you ski, this may mean ice, rock, death cookies, hidden deadfall, and tree boughs don't brush out of the way as you punch through them.
Wherever your line is, one that results in a bloody lip, bruised arm, core shot and a secret pow stash with only one set of tracks on it is a joy. Sparks optional.
