A four-day weather event ending on December 2nd left the inner canyon shrouded in fog beneath liquid blue skies. This phenomenon, commonly referred to as an inversion, created an ironic scenario wherein park visitors felt robbed of an unfettered view of the canyon’s depths, and every local with a camera was running to and fro trying to capture record this rarest of events.
In my nearly twenty years as a park resident, I’ve only seen a handful of inversions. None rivaled the latest in terms of duration and distance (stretching from rim to rim, and spilling over into the adjacent lowlands of the Navajo Nation and beyond). The spectacle was dramatic enough to make national and international news.
