Bruce Bjornstad has 40 years' experience working as a professional geologist/hydrogeologist. After receiving his master's degree in geology in 1980 he started his career working for Rockwell Hanford Operations to characterize a proposed high-level nuclear-waste repository near Richland, WA. In 1990, Bjornstad went to work at Battelle's Pacific Northwest National Laboratory doing environmental clean-up and restoration at the nearby Hanford Site. During this time Bjornstad published dozens of technical publications along with two geologic guidebooks on Ice Age megafloods that transformed the region as recently as 14,000 years ago. In retirement, Bjornstad continues his work on Ice Age megafloods, including an online YouTube channel: Ice Age Floodscapes. In his free time Bjornstad enjoys skiing, hiking, and exploring his Northwest surroundings.
