... most of the data is concentrated in the Laurentide region. We then attempt an inversion for a 1‐D (spherically symmetric) viscosity structure based on minimizing the misfit to these PGR data. Using a Monte Carlo algorithm to invert for two layers of ...

... subsequently migrated through a corridor between the receding Laurentide and Cordilleran ice sheets. This “Clovisfirst” model has been challenged continually by advocates for various allegedly pre-Clovis sites. As the evidence for a given set of ostensibly promising sites fails to withstand close critical scrutiny (e.g., Tule Springs, Pikimachay, Pendejo Cave, Pedra Furada, Shriver, etc.), pre-Clovis enthusiasts pin their hopes on the latest contenders. Currently, their favorites are Monte Verde in southern Chile (Dillehay 1997; Dillehay et ...
