About Our Geology
and Natural History Tours
General Information About Our Tours
Our often multi-day excursions tour some of the best geologic wonders in the United States. Visit some of the richest dinosaur-bearing deposits in the world, and collect amazing trilobites. Decipher the geologic story behind the amazing scenery at Zion, Bryce, and Capitol Reef National Parks, Death Valley, Kelso Dunes, the Great Basin, Redrock Canyon and more. Along the way, we stop frequently to learn about the rocks beneath our feet, or gaze over breathtaking scenic vistas that tell a remarkable story.
Charter bus, breakfast, lunch, lectures, museums, park fees, fossil collecting, a guide booklet and hotels are included in most tour packages. Seating is always limited, so register early!
