Final answer:
When descending hills or mountains, it's important to be alert for hazards like cliffs, quagmires, and crevasses, and to take safety precautions such as wearing helmets and goggles.
Step-by-step explanation:
When going down hills or mountains, one should be especially alert for a variety of potential hazards. These include precipitous cliffs, quagmires, crevasses, and natural hollows which can pose serious risks and should be avoided whenever possible. It is crucial to be cautious of trail erosion, startled wildlife, and to ensure personal safety through protective gear and measured speeds, as echoed by passive trail users and hikers' concerns regarding mountain bikes on narrow trails. Safety precautions are paramount, including the use of safety goggles, helmets, and hearing protectors, to minimize the risk of injury.
Additionally, terrain and weather factors, such as slippery slopes or the thin air at high elevations, can impact breathing and physical performance, further emphasizing the need for vigilance. When taking these elements into account, it's important to ensure that equipment is suitable for rugged conditions and to be alert to the sounds and signs of natural phenomena such as falling water or rockslides, which can indicate the need to proceed with caution or alter one's route.
