Welcome to Les Hasbargen's corner of the web...

ahh, the hop harvest...
I have been a grad student at University of Minnesota, Geology for a while now (since 1994; really Mom and Dad, I will finish this year...). I've stuck my hands into a variety of research projects while here, ranging from field work in SE Oregon (Pleistocene lake levels) and the North Shore of Lake Superior (Holocene stream incision into bedrock), to U-series measurements in old corals from Barbados (with Larry Edwards), numerical landscape evolution modeling, and ultimately, to steady state erosion experiments in a sandbox at St. Anthony Falls Laboratory (since '97, with Chris Paola). I am happily distracted by my natural surroundings, and misguidedly thought that becoming an earth scientist would keep me camped in the wild faroff places. So much for modern earth science...But at least I get to think about nature and natural processes. Actually, I am hoping to return to the wild places and develop methods of monitoring erosion in natural landscapes on a detailed basis. We'll see what gives...
Below you will find links to my thesis research (an investigation into the stability of eroding drainage basins forced with constant climate and uplift conditions). This site is newly established, so it's likely to go through some changes in the coming months...
