- Seasonal Opening Operations require at least one passenger lift to carry members of the general public uphill for downhill skiing or snowboarding on terrain designated open for that use by Big Sky Ski Resort.
- Access counts only when holders of a season pass valid for the specified season can use those lifts and terrain without an additional purchase; free reservations and passholder-only days count.
- Employee, contractor, invited-media, private-event, and separately purchased early-access or preview days do not count.
- Scenic rides, mountain biking, hiking, tubing, and uphill-only access do not count.
- Any number of lifts, any amount of terrain, and any operating duration count.
