This is one awesome hole. I kinda want to go visit it, both when the water is at the level, and below the level of the funnel. Although, i don’t agree with most of the commenters there, i would not jump down it, either full of water, or empty, i like to live, its actually my favorite thing to do every day.
EDIT – 02/27/2017. I removed the link because it no longer points to the original site where these photos came from. Please don’t go there.
