A visit to the @mypubliclands Trona Pinnacles is like a journey to another planet.
One of the most unusual geologic wonders in the California desert, the Trona Pinnacles’ landscape consists of more than 500 tufa (calcium carbonate) pinnacles rising from the bed of the Searles Dry Lake basin.
These tufa spires — some as high as 140 feet — were formed underwater 10,000-100,000 years ago when Searles Lake formed a link in an interconnected chain of Pleistocene lakes stretching from Mono Lake to Death Valley.

Great Basin National Park in Nevada is one of the darkest spots in the United States. What better time to appreciate this park's clear night sky, then on International Day of Clean Air?
Good air quality coupled with a lack of light pollution give visitors majestic starry views of Wheeler Peak. On clear, moonless nights at Great Basin, thousands of stars, numerous planets, star clusters, meteors, man-made satellites, the Andromeda Galaxy, and the Milky Way can be seen with the naked eye.
The area boasts some of the darkest night skies left in the country. Low humidity, good air quality, and minimal light pollution, combined with high elevation, create a unique window to the universe.
