A bison died after falling into Grand Prismatic Spring in Yellowstone National Park. The incident, witnessed by tourists, occurred during the park's peak season. While the exact cause remains unclear, the bison likely stumbled into the near-boiling water (192°F) and perished quickly. Scientists say this isn't entirely uncommon, though this location and timing make it unique. The event serves as a reminder for visitors to stay on designated boardwalks for safety.
