This attraction is a circular, two-story house designed and built by hand out of a life-time collection of rocks, including agates, petrified wood, flagstone, crystals, etc.
There is a floor to ceiling hollow "tree" and a circular staircase. It took the family almost 25 years to complete. The contents of the house include intarsia (thinly cut rocks placed in mosaics to form pictures), paintings of the local wildlife, and 100 wood-carvings (each from a single piece of a different kind of wood).
