Unlike previous expeditions, this small group did not have a scientific mission.  Instead, having heard of Yellowstone's "spouting geysers...the lake, canyon, cataracts, and hot springs," they simply wanted to see the sights.  Thus, they became Yellowstone's first tourists.  Their three-week trip was full of adventures and mesmerizing scenery.  Along the way, they encountered Indians, wild animals, and the famous Hayden Expedition.  

Until now the Clawson trip had been largely unknown and never accessible in book form.  Montana history writer Eugene Lee Silliman discovered the original newspaper articles and researched the trip and its members.  His detailed introduction provides an excellent description of each member of the group and the circumstances surrounding their trip.  In addition to its historical significance, Silliman notes that A ride to the Infernal Regions is "a good read" with well-crafted descriptions and a flair for storytelling.
