BISMARCK, N.D. (AP) - North Dakota State Geologist Ed Murphy will give a talk Wednesday on some of the ways geology might influence, shape or even dictate an area’s history.

Murphy will use center his talk around the history of the railroad bridge which crosses the Missouri River between Bismarck and Mandan.

The original Bismarck Railroad Bridge was completed in 1882. Although the spans were replaced in 1905, the original granite piers remain. That makes them some of the oldest existing structures in the Bismarck-Mandan area. Murphy says innovative techniques were used in the bridge’s design and construction.

Murphy has worked as a geologist for the North Dakota Geological Survey for 36 years, the last 12 as state geologist.

The talk begins at 6:30 p.m. at Bismarck Veterans’ Memorial Public Library.
