In this Monday, July 20, 2015 photo, Bill Lattin, the Southern California Timing Association president and Speed Week race director, stands in the Bonneville Salt Flats in Utah. A small city of tents, trailers and thousands of visitors appears almost every August in the Utah desert to watch cars, motorcycles and anything with wheels rocket across gleaming white sheets of salt at speeds of 400 mph. But wet weather has forced the cancellation of Speed Week for the second straight year and revived a debate about whether nearby mining is depleting the Bonneville Salt Flats of their precious resource.

Cave Diver, Anhumas Abyss, Bonito, Brazil: The Anhumas Abyss is an underground cavern with a crystal-clear lake below, more than 260 feet (79 m) deep. A visitor must enter through a narrow opening at the top of the chamber and rappel into the cave. Snorkeling and scuba diving in the lake reveal amazing scenery. Distinctive, conical limestone stalagmites and stalactites occupy the lake and the surrounding area, some reaching 65 feet (20 m) high. (Photo by Marcio Cabral/Nature’s Best Photography Awards 2017)

Two daredevil photographers have risked their lives to become the first people to capture the explosive moment fiery lava crashes into the sea – while in the water themselves. Fearless duo Nick Selway, 28, and pal CJ Kale, 35, brave baking hot 110F (43,3C) waters to snap the amazing images – standing just feet away from scalding heat and floating lava bombs. Using a simple protective casing around their cameras, and donning just swimming shorts and flippers, they bob up and down with the water as the surf washes over their heads.
