I grew up in Colorado, mostly in Grand Junction, the San Juan Mountains, Lakewood, and finally came to stay in Boulder 40+ years ago. I'm a geologist. I've worked in geological consulting my whole professional career, in Colorado, California, the western US, and Namibia. I’ve always had an interest in science, the natural world, and the physical, biological, and cultural history of wherever I am. I've a lot to learn about Boulder County, and hope to learn and share what I know with others.
