GARDNERVILLE, Nev.—A Northern California wildfire crossed into Nevada, prompting new evacuations, but better weather has been helping crews battling the nation’s largest blaze in southern Oregon.
The Tamarack Fire south of Lake Tahoe had burned more than 68 square miles of timber and head-high chaparral in national forest land. It erupted on July 4 and was one of nearly two dozen blazes sparked by lightning strikes.
