Earlier this month, President Obama's designated the 4,700-acres Chimney Rock Archaeological Area in southwestern Colorado -- an area that is sometimes called "America's Stonehenge" -- as a national monument. The move means that the area between Durango and Pagosa Springs (which was home to thousands of ancient Native Americans) should start seeing an influx of new tourists -- with new thirsts. We'll drink to that -- and so will the Pagosa Brewing Company & Grill, which has brewed a beer, Ancestral Ale, that incorporates some of the foods used by the ancient Pueblo People 1,000 years ago. Ingredients include: yellow squash, Anasazi beans, sweet corn and prickly pear cactus fruit. The beer may available during GABF.
