Uphill Access

While ascending, only authorized uphill-use equipment can be utilized; snowshoeing, boot packing and hiking are not permitted. All skis, including Nordic and splitboards, must be fitted with brakes or retention devices. Skins or climbing scales are required for skis and splitboards while ascending. Uphill ticket/pass are only valid with use of authorized equipment.

Uphill Rules & Safety

We insist upon personal responsibility and respect for others and our environment. Prior to any uphill activity, it is your responsibility to check the trail status for any route closures, as well as weather and snow conditions. It is common for uphill routes and downhill trails to open and/or close any time during normal operating hours. All Uphill Routes close for the day when avalanche mitigation work is being conducted.

Mammoth works hard to provide a safe, consistent and fun mountain experience. To ensure a great day on the hill, please adhere to following uphill safety guidelines.

• Uphill access is only permitted on designated uphill routes during ski area operating hours.
• Be aware of your visibility. Avoid blind spots by remaining visible to all downhill skiers/riders, especially on steep terrain and below abrupt rollovers.
• You must stay on the side of the ski trail while ascending; switchbacking across the trail is not permitted.
• Use caution – snowmobiles, snowcats and snowmaking may be encountered at any time.
• Never ski or splitboard over a snowmaking hose or power cable. If you encounter one in your pathway on an uphill route, you must backtrack to go around it.
• Use of headphones is discouraged to ensure you can hear downhill skiers/riders as well as approaching snowmobiles, snowcats and other on-hill vehicles.
• Never duck a roped or signed closure.
• You must stop ascending and head downhill if Ski Patrol closes the ski trails/uphill route in use due to changes in weather or conditions, or if you are still ascending at the end of the ski area’s operating hours.
• Dogs are prohibited on the slopes. Only service animals are permitted at ski area facilities.
  

Know the Code

We’re committed to promoting safety. In addition to people using traditional alpine ski equipment, you may be joined on the slopes by snowboarders, telemark or cross-country skiers, people with disabilities using specialized adaptive equipment and others. Always show courtesy and be aware that there are elements of risk in skiing/snowboarding that common sense and personal awareness can help reduce. Know your ability level and stay within it. Observe the National Ski Areas Association’s “Your Responsibility Code” listed below to ensure a great day on the hill.

• Always stay in control, and be able to stop or avoid other people or objects.
• People ahead of you have the right of way. It is your responsibility to avoid them.
• You must not stop where you obstruct a trail, or are not visible from above.
• Whenever starting downhill or merging into a trail, look uphill and yield to others.
• Always use devices to help prevent runaway equipment.
• Observe all posted signs and warnings. Keep off closed trails and out of closed areas.

California State Penal Code
