What Was Found Among 20k Pieces of Trash Removed From Yellowstone Hydrothermal Areas
Yellowstone officials said the seasonal cleanup also collected paper, plastic and more than $18 in coins, with hats to be cleaned and donated.
- Yellowstone National Park's Geology Team removed more than 280 hats and over 20,100 pieces of trash from hydrothermal areas throughout the 2026 season, marking a record-setting year for the park.
- With more than 4.5 million visitors annually, high foot traffic and powerful wind gusts at Yellowstone National Park often cause items like hats and trash to blow into delicate hydrothermal features.
- Geologists cataloged unusual recoveries including a FIFA 2026 Men's World Cup hat, AirPods, and a Roblox bucket hat from Kitts and Nevis, along with thousands of other items.
- Trash can clog vents and change water chemistry, potentially causing permanent damage like the color shifts seen in Morning Glory Pool over decades.
- Once the 2026 season concludes, officials will clean and donate recovered hats to local organizations while urging visitors to "stash your trash" in pockets or bags.
