Easy Chair Crater, a Quaternary cinder cone shaped like an arm chair, is in the Lunar Crater field, Nye County. Argenta Price is holding an unusually large crystal (megacryst) of clinopyroxene, which has odd holes that are about a millimeter in diameter and as long as the crystal (3 centimeters).

A Quaternary cinder cone at the north end of Clayton Valley, Esmeralda County, is reflected by the brine pool that is part of the lithium-mining operation in the valley. Lithium-rich brines are pumped to the surface, where they are allowed to evaporate in the sun. The solution precipitates halite, NaCl, before being processed to remove lithium.

Angular unconformity (the originally parallel layering of older sedimentary rocks has been tilted; then younger sedimentary rocks are deposited, more or less in a horizontal package, on top of the tilted rocks, making an angular discordance) in Pennsylvanian-age sandstones and conglomerates, Carlin Canyon, Elko County. The younger sedimentary rocks have been tilted as well, but not as much as the older rocks.
