By Elliot Witscher with Emily Stone In the bright sunlight and heat of the afternoon, the cool, fresh, flowing water from a pipe in Prentice Park in Ashland, WI, was a welcome treat. I wasn’t expecting to find a unique geological feature in an unassuming city park. But walking down the hill from the parking lot, we found a plain metal pipe, surrounded by gravel, with water gushing from it. Standing in a circle with the 20 other people also taking the Wisconsin Master Naturalist Volunteer Training, I learned from Professor Tom Fitz that this was a flowing artesian well.
