"I am a digger of caves and a piler of rocks." 65-year old Ra Paulette, using only hand tools, and with only his dog for company, has spent the past 25 years excavating caves. He is not an architect or a structural engineer; he is a man with an all-consuming passion to create spaces that are transformative. Scraping and shaping Northern New Mexico's sandstone into cathedral-like caves of art (he calls them his wilderness shrines) Paulette has created, massive, awe-inspiring, natural works of art that exposes all who enter to an aesthetic that stimulates deep emotion. Take a look at these "eighth wonders of the world."
