Mike Tripp from the Prineville BLM will chat about mapping of Pleistocene Lakes of Central Oregon using GIS and GPS technology.  The Great Basin had vast numbers of pluvial lakes both small and large that persisted at the end of the Pleistocene. Also, there is evidence that people such as the Clovis Culture and Western Stemmed Tradition lived on these lakes at the end of the last ice age. The Northern Great Basin was no exception, but the lack of data/analysis in our region led Mike to start researching this subject and to ask "How am I going to map out a lake or lakes that no one has ever seen or perhaps even realized was here."  He used many methodologies to get the research rolling such as personal observation in the field, GPSing features on the ground, ground verification of GIS data, and data analysis with vary degrees of complexity. Once the shorelines of the ancient lakes are mapped out, the geomorphology aspect of the study now cross-pollinates with the anthropological. This raised another research question, 'Can shorelines of pluvial lakes of the Pleistocene be used to find very old cultural sites.'  This is a work in progress with more to be done with raster data and high end data analysis. 

Nancy Watson from the Bend PD will talk about how GIS is used in crime analysis, pattern recognition and her day-to-day work.
