How Safety in High-Altitude Climbing Has Evolved

Washington State is home to some of the country’s most diverse climbing routes , incorporating rugged peaks, glaciers and iconic mountain paths. According to the National Park Service, the highest mountain in the state, Mount Rainier, offers mountaineers a climbing experience that is unparalleled within the Cascade Range. While rock climbing is a growing sport in Seattle and offers plenty of opportunities for beginners, high altitude mountaineering can be a hazardous activity. It requires more experience as well as excellent physical fitness in order to minimize the risks of prolonged exertion, lower oxygen levels and falls on rough terrain. To further enhance safety, climbers can now benefit from a number of measures including access to real-time information on mountain environments, durable and smart climbing gear and, in the event of an accident, rescue missions powered by advanced technology. As potential hazards are offset by increasingly sophisticated products and procedures, climbing and hiking can provide a great way to enjoy cardio and improve aerobic endurance without compromising on safety.

Durable Systems and Hardware

At the very foundation of safe climbing is the process of securing lines to the rock face in order to protect against falls. Ropes that were heavy and stiff are now lightweight but reinforced to enhance durability and cut-resistance. The hardware used to work the rope systems needs to work hard in difficult conditions and for this reason, titanium is highly regarded in the manufacture of carabiners, climbing bots and anchors. Due to the metal’s exceptional strength to weight ratio, US titanium manufacturers supply to a wide range of industries that require light but durable components. Titanium is also highly resistant to corrosion and as a result, glue-in bolts made from titanium perform particularly well in coastal ranges like the Olympic Mountains, where they are exposed to saltwater and higher levels of humidity.

Sensor-Enabled Safety Gear

As well as seeing an improvement in the materials and manufacturing techniques, climbing gear has also been enhanced with advanced technology. Smart carabiner systems check that climbers are always connected to the safety line while ropes with embedded sensors can monitor wear and forecast early rope failure.  Safety head gear has long been essential for high altitude climbers in order to prevent head injuries from slips and falling rock debris Now, smart helmets with built in sensors can measure the force of an impact, send out real time data such as GPS location, and even emit an SOS signal if the user loses consciousness. 

Real-Time Environmental Monitoring 

While climbers have control over their choice of safety equipment, the high altitude environment around them is less predictable. Global warming has led to reduced snow cover and melting glaciers which in turn create unstable and changeable terrain. Research expeditions are being undertaken to monitor these conditions and keep climbers informed of long-term changes. Other more immediate changes such as volcanic activity and the risk of avalanche can also be monitored and forecasted using technology-driven systems. In the Cascades, the US Geological Survey Cascades Volcano Observatory keeps a close eye on volcanic activity while route conditions and climber safety are covered by the National Park Service.  At the snow study plot run by the Washington State Department of Transportation, gauges and other measuring equipment monitor changes in the winter snow providing valuable information on the real-time risk of avalanches.

Technology-Driven Mountain Rescue 

As high altitude mountaineering has changed, the safety measures necessary for carrying out successful rescues have also evolved from early impromptu searches led by local volunteers into a specialist service driven by technology. With the use of GPS and global mapping systems such as What Three Words, highly trained rescuers are able to quickly pinpoint the location of stranded climbers. With helicopters capable of flying over 4 miles above sea level, they can carry out extrications even at extreme altitudes and in increasingly remote areas.

While the risks associated with high altitude mountain climbing remain, new advances in equipment, environmental monitoring and rescue operations have improved safety levels. Experienced and physically fit climbers are taking advantage of durable equipment, smart technology and up to date alerts to undertake longer hikes and push themselves to achieve higher ascents.
