Yellowstone National Park attracts more than 4.5 million visitors from around the world every year. Many sightseers arrive well prepared to admire the hotsprings, geysers, scenic lookouts, and wildlife, but there is only so much anyone can do about life’s little unexpected accidents. Each season, Yellowstone’s gusty winds are responsible for blowing away hundreds of hats, maps, and even sunglasses from the heads and hands of onlookers. And every season, park workers scour the grounds to gather up any lost items that landed far from the walkways and trails.

While the tally so far isn’t quite as large as last year’s haul, Yellowstone officials still impressively retrieved more than 280 hats from the hydrothermal areas. Workers cited standouts including a FIFA 2026 Men’s World Cup souvenir and a baseball cap ironically emblazoned with “Cowboy Hat.” But just because they aren’t suited for floating around roiling geysers doesn’t mean they’re destined for a landfill. Once the 2026 season draws to a close, all of the collected hats will be cleaned and donated to local clothing organizations.

Caps are only one type of lost item located amid the hunts. Workers scooped up more than $18 in coins from around the world during the summer search. Canadian dollars, euros, pesos, and yen were scattered among the U.S. change, many apparently tossed into hot springs and geysers as if they were wishing wells. Yellowstone officials took the occasion to remind everyone that hydrothermal formations are not made to receive wished-upon coins. Not only will your dream remain unfulfilled—the foreign additions often introduce destructive algae and bacteria into the delicate ecosystems.

Other common detritus in the haul included plenty of paper and plastic trash, hair ties, hotel key cards, children’s toys, eyewear, and camera lens caps. Standout oddities such as AirPods, an inhaler, and even a single Uno card also made the list of finds.

As always, Yellowstone workers reminded everyone that the seasonal roundup also serves as an excellent reminder to “stash your trash.” Visitors are encouraged to place any litter or lightweight items deep in their pockets or bags until they reach a trash can. And although headwear is always important protection from the sun, people may want to consider temporarily removing their hats while trekking through especially windy areas of the park.
