A misread map, a sudden storm, a forgotten headlamp-and all of a sudden a leisurely hike turns into a treacherous endeavor. In the past 10 years, inexpensive but sophisticated navigation gadgets and cell phones have resulted in alarming degrees of overconfidence in the trail. Adding to this worrisome craze, the increasing popularity of ventures into mountainous surfaces offers led hikers looking for solitude-or an adrenaline rush-into increasingly remote or risky forays. Sandy Stott, the ‘Mishaps’ editor in the journal of the Appalachian Hill Golf club, delivers both a history and a celebration of the search and save workers who conserve countless lives in the White colored Mountains-along using a plea for us not to consider their steadfastness and bravery for granted. Filled with tales of amazing courage and sobering tragedy, Essential Hours will appeal to outdoor fans and armchair adventurers alike.
