I do not remember when I first saw the sections from the seismic survey that had been conducted at Flathead Lake, Montana, in 1970. I arrived at the University of Montana (UM) for graduate school a year after the field work was completed. One day, I returned from class to discover that my officemate had spread out seismic sections on the work tables in the geophysics lab. He told me a little about the Flathead Lake survey and that he was making an interpretation for his thesis project. I do not recall seeing the data very much after that day.
