Alexander Rogers, MS, MA, RPA, Maturango Museum Curator Emeritus

Alexander (Sandy) is Archaeology Curator Emeritus of the Maturango Museum of Ridgecrest, California. He holds advanced degrees in both physics and archaeological anthropology. Over the past 15 years he has published over twenty papers and two book chapters developing and applying the science and mathematics of obsidian hydration dating (OHD). He regularly conducts such analyses in support of CRM firms and academic projects, and is currently working with colleagues on further understanding of OHD at the molecular level. He has led OHD workshops at annual meetings of the Society for California Archaeology, the Association of Oregon Archaeologists, and the Northwest Anthropological Conference.
The goal of this seminar is to provide insight into the theory and methods of obsidian hydration dating (OHD), a useful addition to the archaeologists’ toolbox for chronometric analysis. It should help enable attendees to ask the right questions, principal investigators to select appropriate methods, and analysts in performing chronometric analyses. The workshop will cover the basic principles of obsidian hydration and the models employed in dating; how to control for temperature and obsidian water content; methods for computing a hydration rate; guidelines for data analysis; and numerous cautions. An link to download a summary document on OHD will be provided, and an Excel spreadsheet with numerical models for conducting an OHD analysis. Mathematics will be kept to a minimum, but cannot be avoided entirely.
  1. Describe the science behind obsidian hydration dating (OHD), especially recent advances
  2. Outline the key methods of determining ages with OHD, and the steps involved
  3. Highlight the limitations of the method, in terms of both accuracy and the consumptive nature of the lab work

Reading Flake Scars to Understand Lithic Technologies and Past Human Behavior [Deeper Digs]

When: May 09, 2023 12:00-2:00 PM ET

Duration: 2 hours

Certification: RPA-certified


Individual Registration: $99 for SAA members; $149 for non-members

Group Registration: $139 for SAA members; $189 for non-members

Terry Ozbun, MA, RPA

Terry Lee Ozbun, AINW Senior Archaeologist, studied lithic technology under Dr. Jeffrey
Flenniken and was awarded the Crabtree Memorial Scholarship in Lithic Technology during graduate studies at Washington State University. Terry has published articles and taught classes in lithic technological studies for over 30 years.

Meghan Johnson, MA, RPA

Meghan Johnson is a flintknapper and lithic analyst at AINW. Meghan has taught classes on lithic technological studies for seven years. Meghan’s research aims to identify lithic reduction strategies employed in the Pacific Northwest through technological analysis and experimental replication. Her current research interest focuses on cobble chopper production and use.

Kelley Prince Martinez, MS, RPA

Kelley Prince Martinez is a lithic specialist in technological ground stone analyses in the
Pacific Northwest. Martinez is experienced in conducting macroscopic and microscopic ground stone analyses, combined with experimental replication and use wear studies, to understand raw material selection, ground stone tool manufacture, use, and recycling strategies.

Nick Hlatky, MA, RPA

Nicholas Hlatky has studied lithic technology in the U.S. Southwest, Micronesia, and the
U.S. Pacific Northwest. Nicholas has examined a diverse range of lithic assemblages across these regions, including Clovis, Folsom, and early Archaic period assemblages. He focuses on understanding technological organization through debitage assemblages.
This seminar will provide insight into stone tool production and lithic attribute analysis methods. It will be organized around specific flake attributes and their interpretive power for understanding the processes and techniques used by ancient (and modern) people to make and use stone tools. The course will cover key concepts in interpreting past lithic technological behavior and aims to enhance participants' skills in identification and description of diagnostic lithic artifact attributes.

Key attributes such as remnant ventral surfaces and the characteristics of platforms, compression rings, and radial striations are qualitative more than quantitative and therefore better “read” than measured. Diagnostic attributes vary by technology and their identification allows for reconstruction or modeling of reduction sequences. Reduction sequences (aka chaîne opératoire) represent patterns of learned human behavior and can be evaluated for accuracy through experimental replication. Reading ancient artifacts allows us to discover technologies from the clues left by ancient practitioners of those technologies.

This course is designed for professional archaeologists, students of archaeology, and non-professionals interested in lithic technological analysis.
1. Develop skills in recognizing technological attributes of stone tools and technologically diagnostic debitage
2. Enhance ability to differentiate between natural and human-created flakes
3. Connect attributes to specific reduction technologies and the relationships between individual artifacts and the larger technological systems of which they are a part.

She is also interested in the conservation and care of anthropological materials, and works with museum collections in Wisconsin, Mississippi, and Latin America.
The human skeletal remains curated within archaeological and museum collections belong to those who created the cultures that we seek to understand as archaeologists. Human and faunal remains recovered from archaeological excavations provide a wealth of information about past cultures, but also require the greatest care. The recovery, cleaning, and curation of bone often present one of the great challenges for archaeological projects, as an osteologist may not be on site. What is the best way to transport fragile materials to labs or to export them? How should they be stored until they can be analyzed, or over the long term? Should they be cleaned? Field labs, museums, and universities in remote locations are often only periodically monitored, can have extreme humidity or heat, be infested by insects or animals, lack financial support for collection maintenance, and/or be at risk due to natural disasters like earthquakes or hurricanes. This seminar will describe techniques that osteologists have employed to address these problems as they have worked to curate and house skeletal collections from prehistory through the contemporary era in various sites. The examples will focus on Central America and the ethical and cultural considerations of modern populations.
  1. Review best practices for excavation, transport, sampling, and cleaning human skeletal remains drawing from real world examples
  2. Describe best practices for long-term conservation and curation of skeletal remains drawing from real world examples
  3. Discuss the importance of long-term conservation strategies for collections and our
    ethical obligations as archaeologists
