Archaeologists Don't Always Need to DigThey've Got Drones
On the morning of August 21\u2014the day of the solar eclipse\u2014five archaeologists and I piled into two SUVs and drove an hour northwest of Tucson, into the thick of the Sonoran Desert. Turning off-road, we reached a yellow expanse inside Ironwood Forest National Monument through a series of latched gates. We brought eclipse glasses, but the quarter-sliver of the sun was just a sideshow.
