In September or October of 2021, as the Caldor Fire raged toward Lake Tahoe through eastern California’s drought-addled forests, staff at the Sierra-at-Tahoe ski resort made a desperate bid to fend off the advancing flames: They aimed snowmaking machines at structures and cranked up the water-misting cannons to douse an area that hadn’t seen a lick of rain in months.

A mere 500 miles to the east, a trickle ran down the sandy Dirty Devil River’s broad sandy bed in eastern Utah. Then, a moisture-laden thunderstorm poured its load on the Henry Mountains and filled the arroyos to their brim. Over the course of hours, the Dirty Devil’s flow shot up to a churning 14,000 cubic feet per second—more than four times that of the nearby Colorado River—≠—overflowing the normally dry arroyo’s banks. Six feet of water rushed through Hanksville’s streets and parking lots, washing away cars and filling 500-gallon propane tanks. It also inundated homes and hotels.

This stark contrast is a perfect example of 2021 in West, where the devastating effects and deluges in neighboring countries were juxtaposed. But amid all the weather whiplash, there was one constant: Temperatures were above “normal” all year long.
