McDermitt Caldera
An extinct supervolcano caldera on the Nevada-Oregon border that collapsed about 16.4 million years ago. Its clay-rich crater floor, at Thacker Pass in the southern part of the caldera, holds one of the largest known lithium deposits on Earth (an estimated 20-40 million tonnes of lithium-rich clay), identified in the 1970s and approved for mining in 2021 over objections from environmental groups, Native American tribes and ranchers.
