Far View Reservoir.

Far View Reservoir is another Mesa Verde National Park feature for which its ancient purpose was unclear.  For many years, the Park Service kept two interpretive signs at the site, speculating whether it was an ancient dance pavilion or a reservoir.  WPI determined through detailed surveying, pollen analyses and engineering studies that the circular archaeological site had been a reservoir, but the question remained as to how it was filled.  WPI experimentation and further studies showed that the agricultural area to the south, coupled with an increase in imperviousness due to people walking on the surrounding earth, would have provided occasional runoff to fill the reservoirs.
