In September of 2015, the Llano Quemado Mutual Domestic Water Consumers Association drilled a 
production water well 1.4 miles southwest of the village of Llano Quemado, just south of Taos (UTM-
NAD83 coordinates: 443954 E, 4020825 N). The well is located on the high piedmont of the Picuris 
Mountains, in the southeast corner of the San Luis basin of the Rio Grande rift. The well penetrated thin 
surficial deposits and basin-fill deposits of the Santa Fe Group and Picuris Formation to a total depth of 
1206 ft, and was cased to 1185 ft.

The well owner commissioned geophysical logging of the well. The purpose of this report is to make the 
geophysical logs available to the public.
