Note 4WD track proceeding up the canyon to the left (west). I suspect the ruins begin somewhere in the center of the map frame and proceed west up the canyon. Note: if this doesn't open up in "large" map size format (according to the legend on the left), click on "large" and update.
All of us who are familiar with Mesa Verde, Chaco Canyon, Canon de Chelly, Hovenweep, Bandolier, etc. recognize this is a very significant find.
If you follow the creek up stream on the map series you linked you can eventually find the cabin (and loading chutes) referenced in the article.
