I bought another geology book by the same author as my last purchase. A customer stopped by and gave it a high recommendation. Reviewers complained that much is repeated from the author's other book. I did not find this to be the case. Of course, I am the one who still reads from the book my uncle used at the U of M in the 1950's.
Some day soon I want to go on a rock hunting trip. This can take one of three forms. Either I will go somewhere that has geological features I can photograph. Or somewhere I can pick up samples in the field. Or, somewhere that I can visit a rock shop.
