« Back to Glossary Index

**Group 1: General Safety Measures**

– Carrying the ten essentials is a standard precaution for all backcountry activities.
– Traveling in a group improves safety by enabling first aid, better decision-making, and pooling resources.
– Informing people of the itinerary and carrying a communication device are additional precautions.
– Cell phone coverage in wilderness areas is often poor, so being prepared to hike out for help is crucial.
– Expected hiking time can be estimated using Naismith’s rule.

**Group 2: Dangerous Circumstances**

– Inclement weather like blizzards, flash floods, and tornadoes may require immediate response for survival.
– Lightning poses a frequent and serious threat in many regions.
– Hazardous terrain includes backcountry avalanches, tree wells, icefalls, landslides, and rockfalls.
– Choosing a safe campsite involves avoiding widowmakers and being cautious around slippery surfaces.
Glacier travel requires precautions for crevasses, snowbridges, and drownings.

**Group 3: Navigation and Communication**

Hiking trails should be clearly labeled to prevent travelers from getting lost.
– Carrying a map, compass, or GPS device, and knowing how to use them, reduces the risk of losing one’s way.
– Group leaders should ensure the group stays together to avoid wrong turns at trail junctions.
– Flashing lights, signal mirrors, whistles, and radios can be used as emergency signals for communication.
– Without a focal point or navigational tools, lost individuals may wander in circles.

**Group 4: Health and Medical Concerns**

– Metabolic imbalances like dehydration, hyponatremia, malnutrition, low blood sugar, and hypothermia can affect adventurers.
– Heat-related illnesses such as heat exhaustion and heatstroke can occur in hot weather.
– Altitude-related illnesses like altitude sickness, AMS, HAPE, and HACE can be dangerous.
– Topical injuries like sunburn, frostbite, burns, and lacerations are common.
– Digestive infections from contaminated water sources and poor hygiene practices are risks.

**Group 5: Animal Encounters and Physical Injuries**

– Predatory animals like bears and cougars may attack if surprised or seeking food.
– Insects like mosquitoes, ticks, and fleas carry diseases.
– Internal injuries from falls, ankle sprains, foot blisters, and back injuries are common hiking injuries.
– Venomous animals pose direct harm or anaphylactic shock risks.
– Cumbersome backpacks, improper footwear, and backpack fitting can lead to injuries.

Outdoor recreation, such as hiking, camping, canoeing, cycling, or skiing, entails risks, even if participants do not recklessly place themselves in harm's way. In some circumstances, such as being in remote locations or in extreme weather conditions, even a minor accident may create a dangerous situation that requires survival skills. However, with correct precautions, even fairly adventurous outdoor recreation can be enjoyable and safe.
