Doug: Your message reminds me of a flight I took in 1988 from Miami, FL to Calgary, AB via Orlando and Salt Lake City, UT. I also got the "geologist's seat" (window seat, ahead of the wing) and saw some remarkable scenery. By far the most interesting sight over Florida was the abundance of perfectly circular lakes and ponds surrounding Orlando. I presume these are the result of karsting/sink-hole collapse in the limestone bedrock (?). I was also astonished at the Basin-and-Range district in the Wyoming/Utah area. My view of this area was nearly perfect, and the structure of the whole Basin-and-Range district (including the Great Salt Lake) appeared in textbook clarity, exactly as described in John McPhee's book "Basin and Range" (a book I highly recommend to anyone interested in geology). Other points of interest I remember from my flight were a set of small, perfect cinder cones that I believe were probably in southern Idaho, and the huge, gaping pit of the Anaconda copper mine near Helena, MT.
