Bottom Line
Winter has come in like a lion and left like a lamb. A heavy hitting storm in late November has left us 57 inches of snow on the ground at treeline on Mount Shasta. Currently, strong inversions and dry weather have been in place due to high pressure. This looks to be the continuing situation for the most of the month of December. None-the-less, we are set with a great snowpack base. The Mt. Shasta Avalanche Center daily avalanche and weather forecast is the best place for snow, avalanche, weather and climbing information. Use this resource as your go-to for winter. We will update this climbing advisory information periodically, however the avalanche forecast is updated every 24 hours.
Climbing Mount Shasta in the winter is the real deal. The mountain has fangs that are much sharper this time of year. Should you choose to climb in winter and have questions, give us a call.
As of 12.3.24, the Everitt Memorial Highway is closed at McBride Springs, so access to Bunny Flat is prolonged. Other Wilderness trailheads are also closed, with miles of snow covered roads for access. Castle Lake road is closed at the gate.
Always check the weather before you climb. Winter is approaching. Don't get caught unprepared in poor weather.
All wilderness trailheads are winterized for the season, except for Bunny Flat. You may still access these trailheads, but services are limited. Keep in mind, you are still REQUIRED to carry a summit pass ($25), wilderness permit and human waste packout bag if climbing. These items will NOT be available at the trailhead, thus you will need to get them at Bunny Flat, Mt. Shasta or McCloud Ranger Stations. There is now an electronic fee machine available at Bunny Flat. Credit sales are available for 3-day or annual passes. KEEP THE RECEIPT WITH YOU.
As always, feel free to give us a call to help plan your Mount Shasta adventure. There is something for everyone!
Be Prepared
Our goal is to ensure you have a positive wilderness experience and come home in one piece. To do so:
- BE PREPARED
- DO YOUR RESEARCH
- ALWAYS WEAR A HELMET
- KNOW HOW TO USE YOUR ICE AXE & CRAMPONS.
- CARRY PROPER NAVIGATION TOOLS AND KNOW HOW TO USE THEM
- REMEMBER, YOU ARE RESPONSIBLE FOR YOUR OWN SAFETY.
Accidents and Hazards
Many incidents occur on the mountain every season. The most common accidents include rockfall injuries, lost climbers, and slips and falls in steep terrain. Most accidents can be prevented with proper planning and preparation.
- Do not climb into a whiteout. Always carry a map and compass and/or GPS device and route plan ahead of time.
- Keep your group together. If you split up, have a solid plan and make sure everyone has proper equipment and knows the way.
- Do not glissade with crampons on. If you choose to glissade, take OFF your crampons and make sure the snow is soft.
- Know how to self-arrest properly with your ice axe. A slip and fall on the upper mountain can be fatal.
- Wear a helmet and watch out for rockfall. Climbers get hit every year.
With the right knowledge, skill, equipment, and decision-making, these accidents can be easily prevented. Please, wear a helmet, and know how to use your ice axe and crampons any time of the year.
There is always the potential for thunderstorms during the summer months to shroud the mountain in clouds, limiting visibility. Climbers becoming disoriented on the upper mountain in whiteout conditions and subsequently descending the wrong route is not uncommon. These kinds of scenarios have resulted in many searches over the years. It should go without saying, but we will say it as a solid reminder: Check the weather before you go, and continue to monitor the weather as you climb. DO NOT CLIMB INTO A WHITEOUT! Being caught on the mountain in any type of weather can compromise life and limb.
Understand that if something goes wrong or a member of your climbing party gets injured, you need to be prepared to self-rescue. If you have an emergency on the mountain, call 911. Be prepared to provide your location and the nature of the injury.
Many hazards exist in mountain terrain. Some of these include:
- Ice and rockfall
- Altitude
- Extreme weather
- Avalanches
Icefall and rockfall are possible year-round. It's a simple equation: as snow melts, rockfall increases. If rime ice is plastered to exposed rocks above, it will eventually flake off and fall onto climbers. Wear a helmet and keep your eyes upslope as you climb. Pay attention to other climbers: rockfall is often caused by climbers resting in melted out areas and accidentally dislodging rocks onto slopes and climbers below. Be careful not to kick rocks down onto others.
At the height of 14,179 feet, Mount Shasta is a high altitude peak. It is common for climbers to experience acute mountain sickness (AMS) with signs and symptoms of nausea, headache, and lightheadedness. Despite being a common condition, AMS should not be taken lightly. It can quickly develop into a much more serious and potentially deadly pulmonary or cerebral edema. Rest and hydration are vital to alleviating AMS symptoms. If these symptoms do not improve, your only choice is to descend!
Mt Shasta is a 14, 179-foot volcano with steep slopes, avalanches, glaciers, rockfall, altitude, and extreme weather. Some may feel like Mt Shasta is "safe" due to its proximity to Interstate 5 and its "easy" climbing objective connotation. This is false. One should still expect cold, winter-like conditions at any time of year. Have the appropriate gear AND skill level. Mountaineering is dangerous, and climbers must constantly evaluate the terrain, weather, and many other factors to have a safe trip. One should also not expect immediate rescue. Many factors can prolong rescues. Thus, it is necessary, no matter what mountain of the world, that you be prepared.
Mountain Weather
Check the WEATHER FORECAST before coming up onto Mt. Shasta! Our site's main menu hosts numerous resources on the weather. Researching the mountain weather should be an important part of your trip planning.
Clouds and Precipitation: While you may encounter fair weather at lower elevations, cloud caps can form up high. Never climb into a whiteout, as many climbers have become lost or died in similar conditions. Many routes from all aspects of Mt. Shasta converge on the upper mountain (>12,500 feet). During limited visibility conditions, climbers have descended the wrong side of the mountain. Keep an eye on the sky as you climb, turning around if clouds begin to build on or near the mountain.
Lightning: Mt. Shasta is a 14,000-foot lightning rod and is frequently hit by lightning (usually in summer and fall months), so don't push your luck with building thunderheads.
Wind: Winds can reach over 100 mph at tree line (8,000 ft) and much higher in the alpine region. Winds of 40 mph can knock you off balance. Winds of 60-70 mph can force you to crawl. Hurricane strength winds (>74 mph) can make it nearly impossible to stand and will destroy well-anchored tents. The strongest winds occur with big pressure and temperature gradients in the atmosphere and tend to occur in front of and behind storms. The lowest winds occur when the center of high pressure is over the Mt Shasta area. Take this seriously as the wind has resulted in searches, injuries, and fatalities.
Tips & Notes
Climb early and descend early. This limits exposure to inclement weather (afternoon buildup of clouds is common), allows plenty of time to descend before dark and allows a rescue effort to ensue before dark if one gets injured or lost.
Get an alpine start (2-5 am) and have a turnaround time of 12 to 1 pm. Proper equipment, clothing, and training are a must. Helmets are always recommended and expect rock and ice to fall at any time.
Bring extra warm gear (like a down jacket, balaclava, and extra gloves) in all seasons as climbers often develop superficial frostbite during strong winds. The wind chill temperature near the summit in winter and spring can be well below zero.
Anchor your tent well wherever you camp. Tents can and do blow away frequently. Do not plan to camp above treeline if you do not have anchor lines for your tent.
Solo climbing is not recommended. Traveling with an experienced group is a good idea, and remember - do not split up the group!
The routes on the north and east sides are not recommended for unguided novices; glacier travel and route finding skills are prerequisites.
Mountain Rescue
Do not expect to be rescued. Rather, prevent rescues from happening in the first place, and be prepared to handle rescues within your climbing party should something happen. Nature sets its own terms, and YOU must judge how much risk you are willing to accept.
When to Climb
The BEST time to climb Mt. Shasta is usually from May to mid-July on the south and west sides of the mountain when summer days are longer and the weather is generally stable. However, in dry years, the thin snowpack creates the best climbing conditions in April, May and early June. When the snow melts, you are left with 7,000 feet of scree, talus, and boulders. In heavy snow years, the climbing season extends to August or September. There is NO trail to the summit. Climbing is much safer and more fun on consolidated snow.
A winter climb of Mt. Shasta is possible. Still, it is more difficult and dangerous: extreme weather, short days, avalanches, falling ice and potential post-holing increase the difficulty and danger on all routes. If you choose to travel in the backcountry during the winter and spring, you need to have the proper equipment and training to stay safe. An avalanche beacon, shovel, probe, with the ability to identify avalanche terrain and snow instability, is essential. A climb of Shasta should not be taken lightly.
Every year, many climbers become lost, injured, or killed while attempting Mt. Shasta. Many of these accidents could have been prevented with a bit of pre-planning and training. YOU need to come prepared.
What to Bring
- MANDATORY: wilderness permit, summit pass, human waste pack-out bags. Available for self-issue at all open trailheads.
- THE TEN ESSENTIALS: map and compass, sunglasses and sunscreen, extra food and water, extra clothing, headlamp/flashlight, first aid kit, matches/lighter, stove, knife/multi-tool, bivouac sack.
- HELMET, ICE-AXE, & CRAMPONS
- AVALANCHE BEACON, AVALANCHE PROBE, SHOVEL
Wilderness permits, summit passes, and pack-out bags are currently available at Bunny Flat, the Mt. Shasta and McCloud Ranger Stations and The Fifth Season outdoor store in Mount Shasta City. The Mount Shasta and McCloud Ranger Stations are typically open Monday through Friday from 8 to 4:30 PM. Check our climbing regulations for more details.
Winter and Spring months usually see periods of heightened avalanche danger, though this danger could exist in the summer months under the right circumstances. Research the weather and avalanche danger while planning your trip. Have your climbing party bring avalanche beacons, probes, and shovels armed with proficient skills in their use. Know how to identify avalanche terrain and evaluate snowpack stability.
Shasta Alpine Hut
The stone cabin at treeline on the Avalanche Gulch climbing route is open year-round and all are welcome. However, one cannot sleep inside the cabin, except in emergencies. The composting toilet is closed for the winter and there is NO water available – the spring is buried. If you plan on camping a nominal $3/bivy and $5/tent fee is asked. There is a fee deposit tube inside the cabin. This fragile area gets a lot of use. Please practice Leave-No-Trace principles. Lastly, the property owner, the Sierra Club Foundation, manages its property under the Mt. Shasta Wilderness rules – dogs, horses, and other domestic animals are not allowed. No drones. Thanks!
Dogs
DOGS, AND OTHER DOMESTIC ANIMALS, ARE NOT ALLOWED IN THE MT. SHASTA WILDERNESS OR WITHIN THE SIERRA CLUB FOUNDATION PRIVATE PROPERTY (Shasta Alpine Hut).
