Visiting the wilderness areas of the high rockies of Colorado can be an exhilarating experience. But there are dangers that can ruin or end an outdoor trip. There are also rules and guidelines that wilderness managers have implemented to ensure that future visitors will find the same scenic vistas you have enjoyed.
Whenever you are in a national forest, park, or wilderness location, be sure to follow the “Leave-no-trace” guidelines below. Some public lands will have additional rules so be sure to check with the local authorities. The following are a few leave-no-trace principles.
Visit the Leave No Trace website and read up on the rest of their principles.
Backcountry weather in Colorado is highly dependent on elevation. You can avoid much of the danger weather can bring by remaining alert, monitoring the sky for sudden increases in clouds or a drop in temperature, and wearing the proper protective clothing. Be aware that on the high peaks snow may occur at any time of the year and disorienting fog or mist can put you in a dangerous situation if you are not prepared.
Spring – Late April thru June
Spring snowstorms are very common at elevations above 7k ft . Thunderstorms with lightning become more common later in the season. Hikers will find deep snow at elevations above 9k. ft. Many streams can be difficult or impossible to cross when swollen with snow melt.
Summer – July thru early September
Summer brings milder temperatures with frequent thunderstorms. Thunderstorms bring lightning, hail, snow, wind, and large drops in temperature. Thunderstorms are deadly and the lightning kills hikers every year. Torrential downpours can bring the danger of hypothermia to the unprepared hiker.
Watch for dark clouds moving in from the west and listen for thunder or the wind picking up. This often signals an approaching thunderstorm. Move to lower ground before lightning occurs in your area. Avoid streams or creek beds during thunderstorms as flash floods may occur in low-lying areas. Do NOT make camp near a creek or in a dry creek bed/arroyo.
Fall – Mid September thru October
Fall can bring pleasant and cool temperatures to the rockies. Snow storms (along with frigid temperatures) become more and more frequent as winter approaches. However, thunderstorms can still occur well into October.
Winter – November thru April
Winter in the rockies is a harsh season with frequent blizzards and below freezing temperatures. Proper knowledge of winter camping/backpacking techniques and the right equipment can make the difference between a rewarding expedition and a miserable one. Avalanches present the biggest danger to visitors to the wilderness areas of Colorado. Do not venture into steep snow-covered terrain without avalanche training and an avalanche beacon.
