One of the many secrets which planet Earth has jealously kept from its inhabitants is the microscopic fossil form known as the foraminifer. It hides in common shale, awaiting the patient and painstaking searcher. In furthering the study of the foraminifera of the Colorado group of for­mations in Northern Montana, the United States Geological Survey has collected several suites of shale samples from the Sunburst Dome, five to ten miles south of the Canadian border and twenty-five miles north of the city of Shelby, Montana.
