Highlights surface and near-surface geology
This website deals with the landscape. I will generally avoid topics relating to oil and gas-oriented geology because 1) a wealth of information already exists on that topic, and 2) in North Dakota oil and gas production involves the geology many thousands of feet below the surface of the ground. This website deals with surface and near-surface features.
About John Bluemle
John Bluemle was employed by the North Dakota Geological Survey from 1962 until he retired in 2004. John’s main interest has always been surface geology, the geology of the landforms that can be seen while traveling around the state. Beginning in 2009 John and his wife Mary visited each of the counties in North Dakota and took over eight thousand landform photos. We have selected from among these photos to illustrate current and future articles for this website.
John’s book on North Dakota surface geology, “North Dakota’s Geologic Legacy: Our Land and How it Formed,” was published in 2016 by the North Dakota State University Press. “Geologic Legacy” is far more comprehensive than any of John’s previous publications. It includes many new insights into our state’s geology. Now available at ndsu.edu/ahss/ndirs, the ND Heritage Center Bookshop and a growing number of regional bookstores.
