Yellowstone National Park has removed a record amount of trash from its hydrothermal areas in 2026.

The park`s geology team has collected more than 20,100 pieces of paper and plastic, 5,600 rocks and sticks, 280 hats, 54 camera lens caps, 47 hair ties and 17 pacifiers. Other unusual finds include five AirPods, children`s toys, pressed pennies and over $18 in coins from different countries.

Among the `grossest` finds were six Invisalign retainers, 15 fake nails, floss picks and a lump of glittery pink slime stuck to geyserite.

Park officials warned that foreign materials can damage hydrothermal features by clogging water supplies, blocking run of for introducing chemicals and sediment.
