Piedra Black-on-white is an important type in both sequences defined for both the Northern San Juan and Upper San Juan regions (Wilson and Blinman 1993). While Piedra Black-on-white was named for pottery recovered from the Piedra Valley in the Upper San Juan (Roberts 1930), most of the subsequent descriptions of type are based on pottery described from the Northern San Juan region. In some cases, Piedra from the Upper San Juan may be characterized by slightly lighter leucocratic igneous temper although examples tempered with rock similar to that used in the Northern San Juan are also represented. The occurrence of Piedra Black-on-white at sites in the Upper San Juan dating the early tenth century may also indicate a later end-date for Piedra Black-on-white produced in the Upper San Juan region.
