Pieces of charcoal recovered from two pithouse features at site LA 4921, Three Rivers, New Mexico, were submitted for identification. These charcoal samples are believed to represent horizontal timbers used in construction of the pithouse roofs. Radiocarbon dates range from 1330 to 1140 years BP, with two sigma calibrated ages ranging from AD 640-1020. These dates suggest occupation by the Jornada Mogollon.

Charcoal fragments from a possible burned tree feature on Santa Rosa Island, California, were submitted for identification. This charcoal yielded a radiocarbon date of 12,200 cal BP and is noted to contain the remains of extinct deer mice believed to represent an ancient owl roost. Charcoal was identified to determine the species of the tree.

Four samples from sites 48SW13242 and 48SW7933 in southwest Wyoming were submitted for charcoal identification. Site 48SW13242 is a small, intense open camp, while 48SW7933 is a large, intense occupation site. Charcoal from 48SW13242 yielded an uncalibrated radiocarbon age of 1860 ± 40 BP, and an uncalibrated radiocarbon age of 1270 ± 40 BP was returned for charcoal from 48SW7933.

A total of 89 additional charcoal and wood samples from the Cape Krusenstern beach ridge archaeological site complex were submitted for identification. This site complex is located within Cape Krusenstern National Monument in Northwest Alaska. Charcoal and wood fragments were examined in order to identify the types of wood available to and used by the prehistoric occupants of this site complex, as well as to provide identifications for charcoal samples submitted for radiocarbon dating.

Charcoal from the fill of a basin-shaped hearth at the Elbee Village site (32ME408) was submitted for identification. This hearth was exposed in an erosional cutbank of the Knife River and contained an abundance of charcoal. The Elbee site is an extensive earthlodge village in west-central North Dakota dating to the A.D. 1500s. The hearth was found away from and stratigraphically below the level of the village and might reflect an earlier occupation of the area.

Charcoal samples were examined from on-going excavations at the North Creek Shelter, site 42GA5863, in the Escalante Valley of south-central Utah. These samples were submitted for identification prior to radiocarbon analysis to select the best material to send for dating. The identification of specific material to be dated is particularly advantageous and allows the researcher to know precisely what material is submitted for radiocarbon dating. More accurate ages can be obtained by...

Charcoal from the Stinking Springs Rockshelter, site 48TE1823, was submitted for identification prior to radiocarbon dating. This site lies on a terrace of the Hoback River in western Wyoming. Identification of charcoal will provide information concerning woods burned as fuel in the rockshelter and allows for selection of material with the shortest life span for radiocarbon dating.

Charred "twiggy material" overlying a house floor at site 26CK6444 in the lower Moapa Valley, Nevada, was submitted for identification. The structure had burned, and radiocarbon analysis of charcoal from a burned post base identified as Populus spp. yielded a radiocarbon age of A.D. 125-338. The charcoal fragments submitted for identification were part of a larger sample of charred twigs roughly aligned in a patch and flaring out toward the exterior edge of the house floor. It is possible...

Four sites in Lake County, Oregon yielded charcoal for AMS radiocarbon dating. Ten samples were submitted for analysis to identify the most appropriate material for AMS radiocarbon dating. In addition, four groundstone wash samples, submitted from two of the four sites, were analyzed for phytolith evidence of food processing. All four sites are associated with prehistoric occupations; however, historic artifacts recovered at two of these sites indicate an early 20th Century component.

Twenty-six detrital charcoal samples and one botanic sample were examined to recover organic fragments suitable for radiocarbon age determination. These samples were collected from Holocene terraces along Little Bear River and the East Fork of Little Bear River, a tributary to the Little Bear River, near the towns of Hyrum and Paradise in northeastern Utah. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A total of eight...

Twelve charcoal samples from Site CA-MRN-67 were submitted for identification. This site is a prehistoric shell midden on the eastern shore of the Marin Peninsula in what is now Larkspur, Marin County, California. It is believed to have been inhabited during the Early Period into the Terminal Middle Period (3980-960 BP), possibly representing an ancestral Coast Miwok population. Charcoal and other charred botanic remains were identified to provide information about types of wood burned as fuel...

Two wood samples and one charcoal sample were submitted for identification and AMS radiocarbon dating. These samples were taken from a sandy alluvial deposit at the San Luis Reservoir, Gustine, California. The wood and charcoal fragments have an estimated age of 3,000 to 20,000 BP.

Charcoal and wood fragments were submitted for identification from Menlo Park, California. These charcoal and wood fragments were found with hide fragments at a depth of 90 feet below the floor of the San Francisco Bay at the San Francisco Public Utilities Commission Bay Tunnel Project’s Ravenswood Shaft. Because samples were waterlogged, they were frozen prior to submission.

Five charcoal samples were submitted for identification from the Calendar Site (41BS1517) in Brewster County, Texas. It is hoped that identification of these samples will enrich the environmental database of available plant resources for the eastern Trans-Pecos region during the early Archaic period.

Nine fragments of wood from various portions of the Clarksburg Ferry were submitted for identification. This ferry is the second ferry that operated at Clarksburg, California, across the Sacramento River. The second ferry is noted to have been built in 1920 and was in operation until it sank in 1928. Fragments of wood were recovered from the floor, outer hull plank, longitudinal bulkhead, chine clamp, futtock, end/transverse chine log, lower deck planking, and upper deck sheathing of the ferry.

Sites 24ME163 and 24ME1105 are lithic scatters located along Sheep Creek in the Little Belt Mountains of the Northern Rocky Mountains, Meagher County, Montana. Recent excavations at the sites discovered hearth features at both sites and numerous fire-cracked rock (FCR) at Site 24ME163 (Lynn Peterson, personal communication, July 23, 2019). Hearth feature fill recovered at Site 24ME163 was submitted for macrofloral analysis and AMS radiocarbon age determination. Charcoal samples recovered from a...

Sites 5LA03200, 5LA05698, 5LA10858, 5LA03384, and 5LA04399 are located within the Piñon Canyon Maneuver Site (PCMS) in Las Animas County, southeastern Colorado. Seven features encountered at these sites were sampled for macrofloral analysis (nine samples) and charcoal identification (three samples), to recover and identify charred floral remains and charcoal, indicating food and fuel related activities of prehistoric occupants of this region. Radiocarbon analysis was requested for suitable...

Samples from the fill of two fire-cracked rock features at site 45LE116 in southwest Washington were examined for macrofloral remains. Four samples from midden matrix at this site were submitted for identification and/or AMS radiocarbon dating. This site was examined as part of the Centralia-Chehalis Flood Damage Reduction Project Archaeological Survey. Three radiocarbon dates were obtained from two charred bark samples and one charcoal sample.

Site 7594-1 lies on the crest of a high and narrow ridge 12.2 miles north of Glenrock, in Converse County, east-central Wyoming. Diagnostic artifacts recovered at this lithic scatter indicate Late Archaic (~ 500 BC to AD 1000) occupation (John Greer, personal communication May 5, 2015). Ash fill from the soil probes across the middle of a hearth was submitted for macrofloral analysis and AMS radiocarbon age determination.

Sediment samples collected from 1997 University of Oregon summer field school excavations in the Fort Rock Basin at Sites 35LK2736, 1028-7PC, 1028-13DJ, 1028-14GP1, 1028-14GP2, and 1028-8USA were floated to recover charred macrofloral remains. Charcoal from these sites also was identified. Site 35LK2736 is located on the shore of Silver Lake, and diagnostic artifacts suggest that the site was occupied periodically throughout prehistory. The presence of large boulder house rings suggest...
