Book Review of Archaeology as a Process: Processualism and Its Progeny by Michael J. O'Brien, R. Lee Lyman, and Michael Brian Schiffer

The field of archaeology incorporates a confusing assortment of ideas and approaches to the record. With studies ranging widely in ideology and goals, from strict descriptive materialism to sociological interpretation, language used to communicate key concepts (not to mention which concepts are key) also varies widely, resulting in low levels of mutual interest and intelligibility across the discipline. Archaeologists commonly ignore the majority of available literature as a result, further widening intellectual chasms.

BOOK REVIEW of Oceans of Kansas: A Natural History of the Western Interior Sea by Michael J. Everhart

Just as there are seashells on Mt. Everest, there is an exceptional wealth of fossil remains of marine organisms preserved in the chalk of western Kansas. This Cretaceous-aged rock, and the fossils therein, were deposited at a time when a great sea cut northward across the interior of the continent around 85 million years ago, inspiring the provocative title of Everhart's book. The title is true to its subject: documentation of the Cretaceous fossils of western Kansas, their geographic and stratigraphic occurrences, and the inferences that paleontologists can make about how the organisms represented by these fossils may have once lived and interacted with one another.

Fire History at the Southwestern Great Plains Margin, Capulin Volcano National Monument

This study documents historic fire events at Capulin Volcano National Monument over the last four centuries using dendrochronologically dated fire scars at two sites: the lower volcano lava flows (the Boca) and the adjacent canyon slopes (Morrow Ranch). The mean fire interval (MFI) was 12 years at the Boca site (before 1890) and 5.4 years (1600-1750) and 19.1 years (1751-1890) at the Morrow Ranch site. Data from the Boca and Morrow Ranch sites combined with the extremely pyrogenic landscape position of the volcano slopes indicate that the volcano slopes likely burned more frequently (e.g., MFI <5 yr). Around 1750, the fire regime appeared to transition to longer fire intervals, greater temporal synchrony among fire-scarred trees, and a higher proportion of trees scarred in fire years. Temporal variability in the fire regime at Capulin Volcano may reflect changes in human populations, climate, and land use.
