Exposure in this case refers to exposure to rocks or cliffs, and steep enough that you may not be able to stop if you fall. So they may be a "no fall zone" where you need to be aware of the risk/danger - the exposure to a long fall or injury.I’m psyching myself up for my first trip to Big Sky, in February. I was looking at the trail maps and they have a trail type I’ve never seen before: a triple black-diamond with a red outline. The map key says these runs are “high exposure.” What does this term mean? They’re clearly the hardest runs in the resort. Is this exposure to intense winds-weather?
Several folks at last years Gathering skied Big Coulior, which is one of these slopes and is well known. You have to check in with patrol, as they control the skiing of it. You can read more here:
