Previous analysis of 87Sr/86Sr ratios shows that 10th through 12th century Chaco Canyon was provisioned with plant materials that came from more than 75 km away. This includes (1) corn (Zea mays) grown on the eastern flanks of the Chuska Mountains and floodplain of the San Juan River to the west and north, and (2) spruce (Picea sp.) and fir (Abies sp.) beams from the crest of the Chuska and San Mateo Mountains to the west and south. Here, we extend 87Sr/86Sr analysis to ponderosa pine (Pinus ponderosa) prevalent in the architectural timber at three of the Chacoan great houses (Pueblo Bonito, Chetro Ketl, Pueblo del Arroyo). Like the architectural spruce and fir, much of the ponderosa matches the 87Sr/86Sr ratios...

Contains ca 9000 points representing Wyoming collection sites for plant specimens in the collections of the Rocky Mountain Herbarium (RM). The point coverage is tied to a database of about 190,000 records representing about 1/4 of the holdings of the RM. Collection dates for these records range from the 1860's to 1997, and collections sites are located in general to the nearest section, although the locations of most sites are at best approximate.
