What hikes in the White Mountains are the most dangerous?

The degree of danger associated with any hike is subjective based on the hiker's general hiking experience, physical fitness, safety training and familiarity with the trails and terrain in the region. Many hikes are considered dangerous due to their steep pitches and exposure to the elements, while others can be considered dangerous due to less activity and poor trail blazing, such as bushwhacks. Other factors such as inclement weather can dramatically increase the danger of even a moderate hike. Proper preparedness, familiarity of the trails, understanding of incoming weather patterns and communicating your plans and timing to another person helps reduce risk in hiking the White Mountains, but one always assumes some degree of risk. A simple sprained ankle can mean life or death in bad weather, as the White Mountains, and notably the Presidential Range and Mount Washington, are notorious for life-threatening weather. Combined with very exposed routes and lack of safety equipment, even the most experienced hikers have fallen victim to the White Mountains. For experienced hikers seeking more adventurous routes, one might refer to the popular list "The  Terrifying 25" which provides a list of routes that have steep inclines, a lot of exposure, fun ladders and caves, among other features. Huntington Ravine on Mount Washington is considered the most dangerous in all the Whites for its erratic weather, steep, exposed trails with drop-offs, and less traveled by other hikers.
