The Bonneville Salt Flats just east of Wendover, NV. The remnants of Lake Bonneville, you can definitely see why it gets its name "flats"!! 😁

Time to start sharing pics from recent geology trip. Antelope Island in the Great Salt Lake is a great place to see 1.7 Ga Farmington Canyon Complex migmatites.

On our way to Salt Lake, had to stop by Soda Springs, Idaho to see the (claimed) only captive geyser in the world. The geyser is controlled by valves to erupt every hour on the hour for approximately ten minutes.

If visiting Kodachrome Basin in Utah, take the extra 10 mile trip to visit Grosvenor Arch. A massive double arch in the Henrieville Sandstone, it is named for Gilbert Grosvenor, the first editor and president of National Geographic.
