The author records five months of archaeological fieldwork across New Mexico, Colorado, and Utah, combining reconnaissance and more intensive excavation at Mesa Verde. He documents discovery and description of previously unrecorded ruins, with detailed attention to aboriginal architecture—noting circular and rectangular pueblo forms, masonry, and distribution patterns—and to ceramics as a cultural marker. Specific sites described include a circular ruin called Tebungki or Fire House, its masonry and defensive features, and other cliff and canyon settlements. The report argues for broader regional surveys to understand migration, site distribution, and architectural variation in the prehistoric Southwest.
