Soil samples from between and below two stacked metates sitting atop a hearth at site 5WL6465 in northeastern Colorado were examined for macrofloral remains. Charcoal fragments recovered from the samples were submitted for AMS radiocarbon dating. This site is a multicomponent site containing diagnostic projectile points from the Middle Archaic (3000-1000 B.C.) and Late Prehistoric (A.D. 150-1540), as well as ceramics from the Middle Ceramic (A.D. 1150-1540). Macrofloral analysis is used to...

Fill from a hearth exposed in a cutbank at the Government Creek site (32BI135) in western North Dakota was floated to recover macrofloral remains. Eight charcoal fragments picked from the hearth fill during excavation also were submitted for identification. This site represents a small, short-term, single component occupation on the north side of Government Creek possibly used as a bone grease processing location. Macrofloral analysis provides information concerning plant resources utilized by...

The Skinner Peaks South and Hells Kitchen South trench sites are situated across the Wasatch fault in Juab and Sanpete Counties, Utah. Both sites are located above the Lake Bonneville highstand elevation (Adam Hiscock, personal communication January 29, 2018). Two charcoal and 13 bulk soil samples were submitted for macrofloral analysis to recover and identify charcoal and charred botanic remains suitable for radiocarbon age determination.

Three macrofloral samples were examined from different areas in the U.S. Naval Magazine on Guam. Two samples were collected near the base of Latte stones at the Dobo Site and the LaQuet complex. These sites probably date to the Protohistoric period (AD 1100-1521). The third sample was collected from a small utilized shelter in the Maemong River complex. Utilization of this temporary shelter probably also dates to the Protohistoric period. Macrofloral analysis was requested to identify evidence...

Sediment samples from Swordfish Cave (CA-SBA-503) on Vandenberg Air Force Base, California, were floated to recover macrofloral remains. Two botanic samples also were sent for identification. This site represents a cave in a small sandstone outcrop with rock art panels both inside and outside the cave. A swordfish painted in black on top of a red oval is noted to be typical of Chumash illustrations. Radiocarbon dates suggest that this cave experienced several use episodes, including Early Period...

Sediment samples were collected from the Jacks Valley Trench and the Peavine Trench across active normal faults in Nevada with the purpose of gaining insight into earthquake activity. These sediment samples were examined to recover organic material suitable for AMS radiocarbon dating. Several types of charred macrofloral remains were noted in the Jacks Valley Trench sample. No macroscopic charcoal or other organic fragments were noted in the Peavine Trench sample; therefore, it was processed to...
