My first reaction upon walking through the Chaco Canyon ruins was to be struck by awe, awe and wonder, then marvel at the masonry still partially standing more than one thousand years after the bricks were carefully laid to exacting standards using earthen mortar between the carefully shaped sandstone blocks by ancient hands. Those craftsmen are long lost to the mysteries hidden by long time. The ruins were long ago relieved of artifacts by grave robbers, both amateur (petty thieves) and professional (archaeologists), leaving the crumbling buildings.
