I am sure you are familiar with the Chicago River in the South Branch. Bubbly Creek is used as a nickname for one section of that particular river. During the nineteenth century, a lot of waste was dumped into the water including blood and entrails (livestock) due to which the portion began to bubble with methane and hydrogen sulfide. This particular creek is highly toxic. We are uncertain whether it is fatal or not, but nonetheless, strike this place off your list of places to visit and experience. Unless of course you don’t mind getting terribly sick.
