LIDAR can be utilized alongside archaeological studies
and ground surveying to reveal the Chaco Roads. These roads are estimated to
have been constructed during the Basketmaker III period (500-700 A.D.) and were
used for trade and transportation of people.
Clearly, the impressively parallel outlines of the Great
North Road can be seen on the LIDAR results. The ground surveying done by the
Farmington Bureau of Land Management field office found ceramic shards
concentrated along the same road, noting that the deposits were from different
pieces, rather than whole, broken pots.
