The Great Polarized Light Microscope and the Great Salt Lake

Extract

Teaching on-site courses for the McCrone Research Institute has enabled me to see a lot of the USA. The van and I have been to all of the states except Hawaii and Alaska besides all of the Canadian provinces except Newfoundland and the Northwest Territories. Some parts of the USA have become nearly as familiar to me (and van) as the Outer Drive in Chicago, Rte. 1 down the California coast, Rtes. 80 and 90 to New York and New England, 55 and 65 South, 40 Southeast to Los Angeles and 80 to Salt Lake City and San Francisco, in particular. The latter route across the Great Salt Lake Desert is one of my favorites. That route is always different because of the Great Salt Lake. It's a large lake under normal conditions but conditions are never normal.
