Muddy Mayhem

Paper Bottom

Remember that backyard tarp slip-n-slide your dad set up for you circa 2000?

You’ll find something similar on this underground route. Just hold the soapy water — and add a whole bunch of mud.

It’s survival of the squeeziest down here on Muddy Mayhem. The twists, turns, and tight passageways will work in your favor, as you plant your heels into the soft earth and feel the cool, rock walls underneath your fingertips.

Be sure to pack your sleeping gear. This muddy adventure will keep you underground ‘til morning.
