Bike Park Safety

Bike Park Safety

With hazards and natural/man-made obstacles existing on the trails, be cautious and use common sense.

  • Wear protective gear and clothing – helmets are required.
  • Ride with a partner and pick trails that suit your ability level. 
  • Follow trail etiquette rules: Uphill traffic has the right of way on two-way trails and on downhill trails, the rider in front has the right of way.
  • Be aware of the high altitude environment – the sun is more intense and your body fatigues faster. Stay hydrated and keep an eye on changes in temperature and weather, including thunderstorms.

Safety Checklist

The trails at Mammoth Bike Park are rough and demanding on both the bike and the body. Before riding always inspect your equipment or have it checked by a qualified bike mechanic.

  1. Helmets are required for all mountain bike trails. Before heading out make sure yours fits correctly and is not damaged.
  2. Assess safety pads for fit and any damage. Make sure you are wearing the appropriate pads for you skill level and that coincide with the difficulty of the trails you're looking to ride.
  3. Inspect bike frame for cracks, damaged or dented areas.
  4. Ensure you have sufficient brake pads to stop your bike while descending.
  5. Front and rear axles (skewers) should be tight.
  6. Headset and stem must be secure with no looseness or play.
  7. Check that your tires are in good condition, with no tears or cuts on the rolling surface or sidewall.
  8. Handle bar and handle grips must be tight and unable to spin. Seat and seatpost need to be fastened securely.
If you are not completely familiar with your bike and its various components, these checklist items, or if you have any doubt as to your bike's condition, we highly recommend you check with a qualified bike mechanic for further advice. Visit The Gear Up in the Village for full-service repairs and tuneups.

Your Responsibility Code

Your Responsibility Code

Skiing can be enjoyed in many ways. At ski areas you may see people using alpine, snowboard, telemark, cross-country and other specialized ski equipment, such as that used by disabled or other skiers. Regardless of how you decide to enjoy the slopes, always show courtesy to others and be aware that there are elements of risk in skiing that common sense and personal awareness can help reduce. Observe the code listed below and share with other skiers the responsibility for a great skiing experience.


  • 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.
  • Prior to using any lift, you must have the knowledge and ability to load, ride and unload safely.

This is a partial list. Be safety conscious.

Kids on Lifts

Kids on Lifts

To make your visit as safe and enjoyable as possible, we strongly suggest that you take the time to review the following 11 Kids-on-Lifts Safety Tips with your children before they take their first chairlift ride.

  1. Your small child (defined as a child shorter than 51" to the top of their helmet) may be assisted by the lift operator unless instructed differently by their parent or guardian.

  2. A small child should not ride a chairlift alone.

  3. A small child should sit to the far outside of the chair next to the armrest for added security.  

  4. A small child not seated next to an armrest should be accompanied by an adult.

  5. When riding a fixed grip chairlift with your child (chairlifts that do not automatically slow down while loading and unloading), position them on the side next to the lift operator.

  6. If your child uses ski poles they should take the straps off of their wrists and hold them in the hand away from the outside of the chair while loading.

  7. Once they are ready they should quickly move from the Wait Here signs to the Load Board. They should remember "Boots on the board".

  8. As the chair approaches the load board your child should turn to the outside of the chair, reach back with their free hand, and grab on to the vertical pole. They should remember "Turn, reach, and grab."

  9. Your child should hold on to the vertical bar next to them all the way up the chairlift. They should remember "Hold on".

  10. Your child should sit all the way back in the chair with their back touching the back of the chair. They should remember "Sit all the way back".

  11. Your child should sit still until they reach the Unload Here signs. They should remember to "Sit still".

Our qualified lift staff can assist with loading small children, guests of any age.  Don't hesitate to ask for lift assistance, if needed.

Park Smart

Park Smart

Freestyle Terrain areas are designated with an orange oval and may contain jumps, take-offs, ramps, banks, fun boxes, jibs, rails, half pipes, quarter pipes, snowcross, bump terrain and other constructed or natural terrain features. Prior to using Freestyle Terrain, you are responsible for familiarizing yourself with the terrain and obeying all instructions, warnings and signs. Freestyle skills require maintaining control on the ground, and in the air. Use of Freestyle Terrain exposes you to the risk of serious injury or death. Inverted aerials are not recommended. You assume all risk.

Start Small

Work your way up. Build your skills.

If you are just getting into the park for the first time, or first time that day, start with small features and work your way up. If you aren’t sure about how to use a feature, build your skills first.

When starting out, look for small progression parks and features and then work your way up to medium or large parks and features. Freestyle Terrain comes in different sizes so make sure and start small and work your way up before going into larger parks.

Make a Plan

Every Feature. Every Time.

Every time you use freestyle terrain have a plan for each feature you are going to use.

Remember, your speed, approach and take-off will directly affect your maneuver and landing.

When first inspecting the jumps consider the following elements of each jump:
A – The approach zone is for setting your speed and stance
T – The Take-off zone is for making moves that start your trick
M –The Maneuver zone is for controlling your style
L – The Landing Zone is for getting straight and riding away clean.

Always Look

Before you drop. Before getting into freestyle terrain observe all signage and warnings.

Use your first run as a warm run and to familiarize yourself with the park layout and features

Remember that the features change constantly due to weather, usage and time of day so it is important to continue to inspect features throughout the day.


The features and other users.

One person on a feature at a time.

Wait your turn and call your drop-in.

Always clear the landing area quickly.

Respect all signs and stay off closed features.

Remember that respect is important both in the park, and on the rest of the resort. So be smart when you are heading down the mountain or to the lift and save your best tricks for the park.

Take it Easy

Know Your Limits. Land on Your Feet.

Ride within your ability and consider taking a lesson if you want to build your knowledge, skills, and bag of tricks.

Stay in control both on the ground and in the air.

Remember you can control how big or small you take the feature by varying speed and take off.

Inverted aerials increase the chance of serious injury and are not recommended.

NSAA Recommended Safety Tips

NSAA Recommended Safety Tips

The NSAA has tips for before and during your day on the hill.

Tips for Prior to Hitting the Slope

  • Get in shape: Don't try to ski yourself into shape. You'll enjoy skiing more if you're physically fit.

  • Obtain proper equipment: Be sure to have your ski or snowboard bindings adjusted correctly at a local ski shop. You can rent good ski or snowboarding equipment at resorts.

  • When buying skiwear: Look for fabric that is water and wind-resistant. Look for wind flaps to shield zippers, snug cuffs at wrists and ankles, collars that can be snuggled up to the chin and drawstrings that can be adjusted for comfort and keep wind out. Be sure to buy quality clothing and products.

  • Dress in layers: Layering allows you to accommodate your body's constantly changing temperature. For example, dress in polypropylene underwear (top and bottoms), which feels good next to the skin, dries quickly, absorbs sweat and keeps you warm. Wear a turtleneck, sweater and jacket.

  • Be prepared: Mother Nature has a mind of her own. Bring a headband or hat with you to the slopes, 60 percent of heat-loss is through the head. Wear gloves or mittens (mittens are usually better for those susceptible to cold hands).

  • Wear sun protection: The sun reflects off the snow and is stronger than you think, even on cloudy days!

  • Always wear eye protection: Have sunglasses and goggles with you. Skiing and snowboarding are a lot more fun when you can see.

Tips for while on the Slopes

  • Take a lesson: Like anything, you'll improve the most when you receive some guidance. The best way to become a good skier or snowboarder is to take a lesson from a qualified instructor.

  • ALWAYS SKI OR RIDE WITH A BUDDY: When skiing or riding in deep powder, it is often difficult to get up after a fall. It is especially difficult for snowboarders as their board can anchor them down. Ski Patrol states that it is imperative for skiers and snowboarders to use the buddy system in these conditions. Always arrange a meeting place when you get off a chair, such as the bottom of a chairlift, in case you do get separated. Ensure that the meeting place is close by in case your buddy needs help. If your buddy does not turn up, either search for them immediately or ask a Mammoth Mountain employee to assist you.

  • Warm-up: The all-important warm-up run prepares you mentally and physically for the day ahead.

  • The key to successful skiing/snowboarding is control: To have it, you must be aware of your technique, the terrain and the skiers and snowboarders around you. Be aware of the snow conditions and how they can change. As conditions turn firm, the skiing gets hard and fast. Begin a run slowly. Skiing and snowboarding require a mental and physical presence.

  • If you find yourself on a slope that exceeds your ability level: Always leave your skis on and side step down the slope. Snowboarders should keep their board on and sit low to the ground, using their edge to slow their sliding. In soft conditions snowboarders may take off their snowboard, have the leash around his/her wrist to prevent a runaway board, and walk down the hill.

  • Drink plenty of water: Be careful not to become dehydrated.

  • Curb alcohol consumption: Skiing and snowboarding do not mix well with alcohol or drugs.

  • Know your limits: Learn to ski and snowboard smoothly—and in control. Stop before you become fatigued and, most of all have fun.

  • If you’re tired: Stop skiing. In this day and age of multi-passenger gondolas and high-speed chairlifts, you can get a lot more time on the slopes compared to the days of the past when guests were limited to fixed grip chairlifts.

  • Your Responsibility Code: Always follow the seven safety rules of the slopes laid out in the Responsibility Code above.

Mammoth Safety Tips

Mammoth Safety Tips

Follow these four tips to ensure you and your friends have the best day on the hill.

Make a Plan

Find Terrain That Suits Your Ability

Accidents can occur when skiers and riders find themselves on terrain out of their ability level. Before you head down the mountain, plan out your route using a trail map or the Mammoth App.

Know the Zone

Every Skier/Rider Gets 15 Feet

While on the hill, avoid collisions by giving others 15 feet of space on all sides. If kids are present, go slower and give them even more space. Know that skiers/riders can turn suddenly, so always stay in control.

Stop on The Side

Make Sure You Can Be Seen From All Directions

If you need to stop, be sure to pull to the side of the trail to a place where you are visible to other skiers/riders.

People Downhill Have the Right of Way

Show Courtesy to Others

It is your responsibility to avoid people downhill from you. Be prepared for sudden changes in their speed or direction. Show courtesy by shouting out what side you are passing them on.

SIS/Tree Well Safety

SIS/Tree Well Safety

It's extremely important to keep SIS (Snow Immersion Suffocation) safety at top of mind. Please ski/ride with a partner and be aware of potential SIS locations. 

A tree well/ Snow Immersion Suffocation (SIS) accident can happen when a skier or snowboarder falls into a tree well or area of deep loose snow and becomes immobilized and trapped under the snow and suffocates.

  • Ride with a partner

  • Avoid the base of trees when skiing and riding in deep snow

  • If you are going to fall attempt to do so feet first

  • The more snow, the higher the risk

A tree well/ Snow Immersion Suffocation (SIS) accident can happen when a skier or snowboarder falls into a tree well or area of deep loose snow and becomes immobilized and trapped under the snow and suffocates. Falling headfirst is the most common position SIS incidents occur. 

  • Breathing becomes difficult when trapped under snow as loose snow packs in around you. Without an immediate rescue you can suffocate.

  • The easiest way to avoid an SIS incident is to ski or ride with a partner and use extra caution when deep, loose snow exists - especially where trees exist.

  • Odds of surviving an SIS incident when skiing/riding alone are low.

  • Prevention of falling into a tree well or area of deep snow is extremely important, odds of surviving deep snow immersion are low.

  • 90% of people involved in Tree Well/SIS hazard research experiments could NOT rescue themselves. 

  • If a partner is not there for immediate rescue, the skier or rider could die extremely quickly from suffocation - in many cases, the time corresponds to drowning in water.

During SIS hazard research experiments, 90% of the research participants could not rescue themselves. Skiing/riding with a partner is crucial as death from drowning can occur in the same amount of time it takes in water.

About Tree Wells

  • A tree well is a depression that forms around the base of a tree that contains a mix of low hanging branches, loose snow and air.

  • Evergreen trees in particular (fir, hemlock, etc.) can have large, deep tree wells that form when low hanging branches block snow from filling in and consolidating around the base of the tree. These voids can be hidden from view by the tree’s low hanging branches.

  • There is no easy way to identify if a particular tree has a dangerous tree well by sight therefore, treat all tree wells as dangerous.

Illustration of tree well

Tree Well/ SIS Accidents Happen in Ungroomed Terrain  

  • Most Tree Well/SIS accidents happen where there is a combination of deep powder and trees, exactly where a vast majority of powder hounds want to ski/ride. 

  • Big storms make for epic powder days, but they also make for some extremely dangerous Tree Well/SIS conditions.

  • The more fresh snow the higher the risk!

  • Staying on groomed runs can greatly reduce the risk of an SIS incident.


What to do if You Go Down

  • Yell or use a whistle to get your partners attention.

  • Do whatever you can to keep your head above the surface of the snow. Roll around, grab tree branches or the tree trunk, anything to keep from descending further. 

  • If possible, keep your feet below the level of your head.

  • If you become immersed: Make a space around your face and protect your airway/stay calm/trust your partner is on their way.

  • If possible, use your cell phone to call Mammoth’s emergency hotline: 760.934.0611

What to do if Your Partner Goes Down

  • Don’t leave to get help – Stay with your partner!

  • Call for additional resources. Use a whistle or yell for assistance. If possible, call 760.934.0611. 

  • Evaluate scene safety for yourself.

Immediately Begin Snow Immersion Rescue Efforts

  • Go directly for the airway, and make sure to keep it clear.

  • Be careful not to knock more snow into the hole.

  • Do not try to pull victim out the way they fell in. Instead, determine where the head is and tunnel in from the side.

  • When tunneling directly for the airway be careful not to knock more snow into the hole.

  • Continue expanding the tunnel to the airway until you can extricate the body. 

Safety Measures for Ungroomed Terrain

  • Ride or ski with a partner and keep them IN SIGHT at all times.

  • Ski or ride in control.

  • Give tree wells a wide berth and look at the open spaces between the trees, not at them.

  • Skiers should remove ski pole straps.

  • Use common sense and look after one another out there.

Carry Safety Equipment

  • Cell phone with (760)934-0611 on speed dial

High Altitude Tips

High Altitude Tips

Mammoth offers many recreational opportunities from downhill skiing and snowboarding to mountain biking, rock climbing, and horseback riding. The center of town is approximately 7,500 ft above sea level, and the elevation at the base of Mammoth Mountain near the Main Lodge is 9,000 ft, with the mountain's summit towering at 11,053 ft. Expand this box below and follow the tips to avoid any side effects from effects due to Mammoth’s high elevation.  

Altitude Adjustment

When you first arrive, acclimatize yourself for a period of time prior to beginning any strenuous activities. At high elevations, the atmosphere is thinner and there's less oxygen and humidity available than at sea level. This can result in a number of symptoms, such as muscle fatigue, insomnia, mild headaches or slight shortness of breath. 

Avoid Sunburn

Our thin atmosphere filters out only a minimum of the sun’s ultraviolet (UV) rays and can result in severe sunburn. Be sure to take adequate precautions to protect your eyes and skin. During high-exposure activities such as spring skiing, those with fair skin may experience sunburn after only two hours of sun exposure, even after applying maximum sunscreen protection. Parents should be especially careful with young children, and apply a generous amount of sunscreen prior to any outdoor activities.

Keep Warm

At this higher elevation, the weather can change quickly. Prolonged exposure to the elements can cause serious problems in any season. Children are not always aware that they are becoming too cold. Parents should watch for red noses and red ears. If this occurs, bring the child in from the cold, remove wet clothes and warm the child and affected areas immediately. Take frequent breaks from the cold or heat. It is wise to layer your clothing, no matter what the season. A t-shirt, wool sweater, nylon windbreaker with hood and a bottle of water are basics for just about any summer activity. Winter sports enthusiasts should wear warm, water-resistant clothing and goggles or sunglasses with adequate UV protection.

Eat Lightly and Drink Plenty of Liquids

You may tend to become dehydrated more quickly at high altitude than at sea level, so drink plenty of water and other fluids (at least 8–10 glasses daily). You should also avoid drinking alcoholic beverages for the first 24 hours of your stay. 

Protect Your Eyes

It is also important to use proper UV protection for your eyes. The surface of the snow or water can act as a reflector of UV rays and can generate a great deal of UV exposure to the eyes. Equip yourself and your children with UV sunglasses or goggles. Failure to wear proper eye protection can result in an actual burn of the eye’s surface – a painful condition requiring medical treatment.  

Listen to Your Body

If you experience symptoms such as headache, insomnia and/or fatigue, you may have a mild form of altitude sickness. These symptoms are a warning to decrease your activity level. If symptoms persist or begin to worry you, don’t hesitate to contact ski patrol or get checked out the Mammoth Hospital.  


It’s wise not to have an alcoholic drink at lunch if you plan to return to the slopes afterwards. Most ski accidents occur in the afternoon, as muscles begin to fatigue. The effects of muscle fatigue are increased by the consumption of alcohol.
