Geoarchaeology and Drinking Straw Technology

Sinkholes are unreasonably complex phenomena – those in rivers doubly so. If you can figure out their geological history, you have a better chance of figuring out how artifacts got there. As far as I can tell, this is not a straight forward task. As time goes by, sinks are subject to slumping, flood deposits, […]

In previous years, divers needed powerful lights to work even just 15 to 20 feet from the surface. This was not a typical year. The climate worked in our […]

We took a number of cores from Forest Canyon Pass to help reconstruct the saddle’s paleoenvironment. The small alpine ponds and wetlands have beautiful pollen records. The trick was to find one with deep enough sediments. We finished coring just in time. An afternoon storm came up over the pass, and we had to boogey. […]
