This is a two-part presentation of research on the quasihuman ichnofossils (supposed human tracks) found in strata with the tracks of dinosaurs near Tuba City, Arizona. The material for study was collected on field trips made on June 21-27 and October 15-18, 1990 and June 1-6, 1995. This project is a continuation of previous research at Site 2. We give some corrections concerning tracks at Site 1 (See Rosnau, Auldaney, Howe and Waisgerber, 1989a, b). Photographs, maps, descriptions, reevaluations and additional discoveries at the two main ichnofossil areas at Site 2 (H6 and H7) are presented for the first time. We compare contemporary human trackways and dinosaur trackways to the quasi-human ichnofossils in the "Downhill Trail." The results indicate the humanoid ichnofossil impressions match modern human tracks and not dinosaurs for size, stride and shape. In an appendix we present corrections concerning certain tracks. In Part II we will present evidence from photomicrographic analysis. We will compare modern human tracks to quasihuman ichnofossils and describe additional newfound humanoid tracks at Site 2. We will present the authors' updated conclusions and answer criticisms of our work.
