This odd creature is one of the strange formations at the Mushroom Rock State Park, the smallest park in Kansas. These "mushrooms" were formed when the softer rock below eroded faster than the harder rock above.
For the full feeling of my visit, insert waist-high wildflowers, drizzly rain, and lots of squishy mud to step in. I was the only person there. It was cool to be alone in that strange world. It's funny, though. These rocks do not call to me at all creatively, as compared to these which do. I had to write a whole new novel around that second set of rocks, but these "mushrooms" don't require me to do the same. Maybe they'll inspire you. :)
