With over 20 years experience in geoarchaeology, the staff at the GBL have guided the environmental and geoarchaeological research of nearly 100 CRM projects from a broad range of archaeological and geological settings throughout the Eastern and Midwestern USA.  These include large-scale pipeline and highway corridor studies that required extensive regional synthesis and close integration with the Phase I, II, and III archaeological studies, deep test projects that accurately and cost-effectively explore for buried sites, and smaller-scaled individual archaeological projects.  For example, G. William Monaghan brings a breadth of experience in Quaternary geology, sedimentology, pedology, archaeology, and prehistoric site formation rarely encompassed by other CRM teams.
