Dr. Stephen Janes is an archaeologist who holds doctorates in geology and paleontology. Ground surveys conducted through his research in the southwest have revealed a network of ancient lines crossing the San Juan Basin and adjacent mountainous areas of New Mexico and Arizona. Separate from the inferred Chacoan “road” system, this linescape is defined by the alignment of numerous small structures, linear sherd scatters, and distinct landforms. Two sets of lines occur in the basin trending east to west, and northeast to southwest. Mapped in detail, these lines extend at least 70 kilometers and beyond the basin, suggesting they are part of a much larger linescape and may be continental in scope.
