Artic Paths
 This is a paper on using a methodology to discover evidence of people using the then existing coastline for dispersion from Asia to Alaska, with a focus from Kodiak Island to the Columbia River. The method uses Seismic Reflectivity data to search for patterns caused by the stonework in winter homes buried in sediments or on the surface for the depths from sea-level to about 60 fathoms. The intent is to establish with seismic reflectance data where previous dwellings are in this narrow band of coast under today's sea-level.

Nowadays I think the best way to search is with the data itself, and not visually. Getting more familiar with that idea and the input data. The plan is to find the high reflectance data peaks and then examine those areas at the highest resolution of the data. Since the areas are small (2-4m in diameter), and the background scatter is highly reflectant, with a lot of scattering, the data pattern of a winter home should be unique from the backscatter of a layer of coastal conglomerate under lighter sediments or scoured since submersion. The visual prints of tracks are harder to examine accurately, I've taken track photos into graphic programs and separated out unique tones in 256 grays, lots of interesting looking results...but nothing to hang a hat on. Digitally, I think it can be nailed down using the power values of the return signals. All those flat rocks facing the transmitter should return a high power return area above the backscatter of the conglomerate.

High Rock Lake
 This is a distillation of the story of a series of bike tours which ended up engaging me in the study of archæology, having been drawn to the area by it's geology, and, it's dry in the fall. High Rock Lake is in a basin which captures over 250 square miles of watershed, precipitation is mainly snow and thundershowers for this high basalt plateau. The rocks also include old deposits of obsidian nodules and calcedony and chert, very good for stone tools. The article includes bibliography.
