My name is Mohammed Hassan Alief. I'm a practicing geologist in Denver, Colorado. I'm originally from Afghanistan and went to school in Golden, Colorado, and Moscow, Idaho, and have been practicing geology since 1960. I did try to work in Afghanistan in 1962-66, but due to harsh economic conditions, I immigrated to the US and have been here ever since. In these days immigrant bashing is a sport among some people, but in reality, immigrants are the backbone of this country.
