Avalanche Hazard Information

Note: This Avalanche Hazard Information pertains to the 10th Mountain Division huts, the Summit Huts Association huts, the Grand Huts Association hut, and all of the privately owned huts. For important avalanche hazard information about the Alfred A. Braun Huts and the Friends’ Hut, please link to their pages from The Huts menu and review all alerts and warnings.

Colorado is known for its avalanche prone snowpack. A number of the suggested routes to 10th Mountain Division Huts pass through or are next to terrain that may be prone to avalanches. Accordingly, pick the suggested route that most suits your group and its abilities, carry appropriate equipment, and always exercise prudent backcountry travel techniques when passing through avalanche prone terrain. Remember, avalanches can occur in forested areas and can run into forested areas from open slopes. Moreover, a number of huts booked are situated in the midst of extreme avalanche terrain. Many other huts, while located in more modest terrain, still have access routes that cross avalanche paths.

We strongly suggest that someone in every group be experienced in evaluating avalanche and snow stability hazards and practicing prudent backcountry and winter mountain travel techniques. For up to date avalanche information for all of Colorado, visit the website for the Colorado Avalanche Information Center (CAIC). Another excellent resource is the Forest Service National Avalanche Center website. While this site doesn’t have local forecasts it does have a wealth of information on backcountry travel in avalanche terrain and snow science, as well as tutorials on some basic skills and snow science.

We recommend that you start checking the Colorado Avalanche Information Center (CAIC) Website regularly before your trip to see how conditions are evolving. Study your maps to see what type of terrain you will be traveling through to see if there are alternative routes that might be feasible if snow stability conditions deteriorate. During most of the winter, travel to the huts, other than those in the Braun Hut System and the Friends’ Hut, is possible with a relatively minor degree of risk. However, if your trip falls within a period or cycle of high or extreme instability, you must make the decision of whether or not to go. The huts are not closed for avalanche hazard reasons. While deep snow, bad weather, and white-out conditions are to be anticipated on any trip, a hut credit may be issued if a trip is cancelled due to avalanche danger associated with an extreme avalanche cycle. To be considered for hut credit under these circumstances, please send us a detailed email and we will reply as soon as possible.

Information about avalanche activity along suggested routes that has been observed or reported by staff members, guides and hut users is recorded on this website; start by going to The Huts menu, select the appropriate hut page, scroll to that hut’s Trailheads/Routes section, select Winter, then select the dark blue Route Description button of the winter route you want to review. If avalanche activity has been reported on the route, you’ll see a warning note in orange, followed by details at the bottom of the route description about the location and rating of the observed or reported avalanche activity. If avalanche activity has not been observed or reported – this will also be noted, but does not indicate that avalanche activity will not occur in the future. Our avalanche activity records are location-based; we do not report observation dates or show repetition. We welcome new information.

Avalanche size/destructive force is based on SWAG-Snow, Weather and Avalanche Guidelines of the American Avalanche Association.

Size-Destructive Force

    • D1 Relatively harmless to humans
    • D2 Could bury or injure a person
    • D3 Could bury a car, damage a truck, destroy a wood frame house, or break a few trees
    • D4 Could destroy a railroad car, large truck, several buildings, or a substantial amount of forest.
    • D5 Could gouge the landscape, largest snow avalanches known.

 

Global Positioning System (GPS) Information

The following GPS coordinates were collected with the best available tools at our disposal. While we strive for accuracy in our data, discrepancies may still exist between our coordinates and coordinates you may take in the field.

10th Mountain advises against relying solely on a GPS for use in accessing the huts because they may not provide the desired accuracy due to weak satellite signals caused by forest cover, inclement weather, topography, less-than-ideal satellite positions, and other factors. If you are going to use GPS we would suggest that your party have more than one unit to double check your coordinates.

GPS and Smart Phones

As smart phones have become more powerful and their GPS capabilities have improved, more and more people are using them as a GPS instead of purchasing a separate, stand-alone device. When paired with a good mapping app, the increased screen size and resolution of most modern smart phones is big improvement over the smaller screens of many stand-alone GPS units. We recommend the Gaia GPS App for mapping on your smart phone, it has a very intuitive interface and powerful trip planning tools. Gaia has provided an instructional hut-trip-planning video below that is packed with useful info. Gaia GPS is also offering hut users a free 3 month trial of Gaia GPS premium so you can safely plan your next hut trip with Gaia GPS. 10th Mountain Division Hut Visitors get access to the full map catalog and the ability download your maps for offline use with 3 months of Gaia GPS Premium. Gaia GPS Premium Free 3 month trial!

A GPS unit can be a good tool for backcountry navigation when used in conjunction with a map, compass, altimeter and appropriate skills. If your GPS fails, you will be very thankful that you wisely brought your map, compass, and altimeter – and know how to use them. If you would like to know more about GPS accuracy and the different variables that can affect it we have included links to some useful info at the bottom of the page.

GPS FAQ’s

Should I use my GPS to navigate to the hut?

10th Mountain advises against relying solely on a GPS for use in accessing the huts because they may not provide the desired accuracy due to weak satellite signals caused by forest cover, inclement weather, topography, less-than-ideal satellite positions, and other factors. A GPS unit can be a good tool for backcountry navigation when used in conjunction with a map, compass, altimeter and appropriate skills. If your GPS fails, you will be very thankful that you wisely brought your map, compass, and altimeter – and know how to use them.

What is a mapping datum?

A datum is a mathematical model of the Earth which approximates the shape of the Earth and is used as a reference on maps. It enables calculations such as position and area to be carried out in a consistent and accurate manner even though the earth is not perfectly round, but is spheroid in shape. Every map has a map datum reference that is usually listed in the title block or legend of the map.

Why do I need to know about mapping datums and which one should I use?

When using a map and GPS together for navigation, your GPS must be set to the same datum as the map you are using. Failure to do so could result in errors of 200 meters or more in your displayed position. This is because the same position on earth (a hut or trailhead for example) will have different coordinates depending on the datum used to create the map. Most United States Geological Survey (USGS) topographic maps and ALL 10th Mountain Division Hut Association winter maps are referenced using NAD 27. Some newer USGS maps use NAD 83. If you are using your GPS without a map (shame on you for not having a map!), using WGS84 is generally the best datum to use as it is considered the most accurate datum to use with a GPS alone. Consult your GPS owner’s manual to learn how to set the correct datum to match your map’s datum.

Why are there two mapping datums?

Over the years, many different datums have been developed and used as references on maps all over the world. NAD27 (1927 North American Datum) and WGS84 (World Geodetic System 1984) are the two most predominantly used in North America today.

REMEMBER! when using a map AND GPS together, BE SURE YOUR GPS IS SET TO THE SAME DATUM AS YOUR TOPO MAP! Failure to do so could result in errors of 200 meters or more in your displayed position. Consult your GPS owners manual to learn how to set the correct datum to match your map’s datum. Note that most GPS units come from the factory with WGS84 as the default map datum.

Emergency & Self Rescue

If a member of your group is injured or becomes ill at a hut or along the trail you cannot rely on outside help. Communication of any kind with the outside world, even in an emergency, is not possible from most of the huts. Cell phone reception is spotty and cannot be relied upon. Your group must be prepared and equipped for a bivouac, rescue, evacuation, equipment repair or handling of other misfortunes that may be encountered.

Several members of your party should be trained in first aid. Such training may be obtained by taking the requisite courses for an American Red Cross advanced first aid certification. Contact your local chapter of the Red Cross for details. Hut users who frequently travel in the backcountry should consider training beyond standard first aid. The CU Mountain Medicine Course is a good place to start looking for such training.

In the event of an emergency, CALL 911. Texting 911 is only available in some counties, see below. If a person is reporting an emergency on behalf of someone on a hut trip, they can call the Non-Emergency Dispatch of the county where the hut is located, see below. Any rescue effort may be slow, if available.

Summer Water Source Information

Collecting & Filtering Stream Water for Drinking

The list by hut below provides approximate locations of nearby streams where guests collect water for drinking. It is the hut customer’s responsibility to filter the water they collect. FILTERS ARE NOT PROVIDED – DON’T FORGET TO BRING YOUR OWN! If you don’t have a filter, boil stream water on the hut’s propane burners. If your group is driving a support vehicle consider bringing your own water.

A Note About Water Filter Use: In order to minimize contamination of the plastic water jugs from the dirty end of your filter, we ask you to transfer the unfiltered water into one of the hut’s cooking pots – which are easier to clean – and filter from the cooking pot into your own clean containers. When you are done filtering your water please wipe down the metal pot and allow it to air-dry.

All huts* have large plastic water jugs or pails to transport water from the stream to the hut. Many huts have water-carrying backpacks (see below for availability by hut). Some water sources are shallow and the collection jug probably can’t be submerged, so in addition to the water-carrying pack, we suggest bringing a small pot or water bottle to help transfer stream water into the jugs.

*Shrine Mountain Inn (Jay’s, Chuck’s and Walter’s) and the High Lonesome Hut are the only properties with potable, hot and cold running water. Guests may drink the water from the kitchen and bathroom sinks at these huts right from the tap!

Using Cistern Water for Cleaning

Many huts have hand pumps in the kitchen sink that dispense water from various types of cisterns. The suggested use of cistern water is for cleaning only unless stated below. Availability of cistern water depends on precipitation and conservation by previous users, and could be completely dry.


Summer Water Source Information – By Hut
