DEBERT BELMONT: A REMARKABLE SITE COMPLEX Revealing one of the largest Paleoindian sites in North America at the time, the Debert excavations identifi ed nu- merous loci with large quantities of varied diagnostic tools and debitage and multiple hearth and pit features. The tool assemblage is one of the largest in eastern North America, with more than 4,600 formal tools and 23,000 pieces of debitage, including 140 fl uted points (Ellis 2004; MacDon- ald 1968; Robinson et al. 2009:428). The broad range of formal tools represents a full suite of domestic, manufac- turing, resource procurement, and processing activities as- sociated with a combined site area in excess of 19,000 m. The publication of MacDonald’s (1968) site monograph and related articles (Borns 1966; Byers 1966; MacDonald 1966; Stuckenrath 1966) established Debert as a hallmark of interdisciplinary research in the region. The legacy of the site has provided crucial baseline data for a wide range of subsequent research investigating the nature and extent of settlement and social aggregation (e.g., Dincauze 1993; Robinson et al. 2009), lithic analyses (e.g., Ellis 2004), 6.1.

The geologists and soil scientists working with MacDon- ald defi ned the depositional and environmental contexts of the Debert site, situating it chronologically and spatially more securely than most other sites had been to date (Borns 1966; Lyford 1964; Swift 1965). MacDonald identifi ed three major sediment facies above the Triassic bedrock: till, lami- nated sands, and structureless sand (fi gure 6.2). The site’s stratigraphy was considered to be relatively simple, with artifacts found solely in the structureless sand facies (Mac- Donald 1968:6). MacDonald argued that the structureless sand was the “organic working of the underlying structured sands,” which were eolian in origin. He (1968:18) docu- mented the removal of surfi cial material (up to 30 cm in some cases) and demonstrated (1968:11) that there was no correla- tion between soil horizons and strata containing cultural 6.2.
