Social trail or social media? Christian Beckwith on Delta Lake’s future.

There’s no official trail to Delta Lake in Grand Teton National Park. But on any summer day in the last five years, its 500-some daily visitors would signal otherwise. Many are what Christian Beckwith described as the “nontraditional” park visitor. “We're talking flip flops and bikinis and boom boxes,” he said. “In my mind, this is the most incredible opportunity the park has probably ever had.”He talks with co-host Frederick Reimers about the balance of wilderness and access in one of the world's most Instagrammable spots.
