Horrified tourists watch as bison boils to death in Yellowstone hot spring

Tourists at Yellowstone witnessed a bison's tragic death after it fell into the near-boiling waters of Grand Prismatic Spring, becoming trapped and unable to escape.

Rachel Wolf is a breaking news writer for Fox News Digital and FOX Business.

"Unfortunately, I witnessed the bison drowning in the Grand Prismatic Springs early yesterday morning. It took a few steps into a shallow area to the right of the pool, it turned around and stepped out very quickly. It stood for a moment, then turned back towards the spring and stepped into a deeper section then couldn’t get out despite trying its best. I have a video of it coming up to take its last breath but it’s a tough watch," Louise Howard wrote in a Facebook post with the photos.
