Among America’s great treasures are its national parks, monuments, nature preserves, and historical sites. Many of America’s national parks feature unique and spectacular geology. Sigma Gamma Epsilon chapters, geology clubs, and individuals are encouraged to organize and submit a photo array featuring the geology of a particular national park or monument.
