In Context

“In 1920, the town council of Chamonix … decided to change the municipality’s name to Chamonix-Mont-Blanc, thus forging an official link to the mountain … with a summit that soars 12,000 feet above the town center. The council’s goal was to prevent their Swiss neighbors from claiming the mountain’s glory, but there was really no need: It’s impossible when you’re in Chamonix to ignore the gargantuan, icy beauty that looms overhead.”
