Resurrecting Megajeff: Uncovering the Hidden History of IU's Lost Megalonyx jeffersonii DI22

"Megajeff" is a nearly complete skeleton of a Megalonyx jeffersonii giant ground sloth that once existed within the natural history collections at Indiana University. Surviving fossilization, railroad transport, and fire, the specimen was ultimately destroyed by a lack of understanding of the importance of natural history collections.

Indiana's Hindostan whetstone industry DI23

Hindostan whetstone is a thinly layered siltstone that was quarried in southern Indiana throughout the 19th and 20th centuries for use as sharpening stones and grave markers. Produced exclusively from northwestern Orange County, Indiana, this abundant material supplied the state’s first mineral industry and was exported throughout the United States, Europe, and Asia.

Petroleum Industry in Indiana B42N-1975

Petroleum---the subject of this paper---has fascinated mankind since its earliest discovery. Crude oil and natural gas are so closely related in nature that they will be treated together under the general heading of petroleum. Petroleum production in Indiana began in 1886, has continued without interruption to the present, and will continue into the foreseeable future. Exact gas production figures are unknown but exceed a trillion cubic feet. Crude oil production exceeded 438 million barrels through 1973. Of the 32 oil-producing states, Indiana ranked 22d in annual production in 1973. The small independent oil companies are the backbone of the petroleum industry in Indiana. They range in size from those that have only a few employees to some that have many. The large inter­national "major" companies conduct limited operations here. Inde­pendents drill most of our oil and gas test wells, and they produce most of our oil. The geology of petroleum from its origin to its production is summarized in a general way in this report. Emphasis is designed not to make the reader an expert but to inform him of the general geology involved in petroleum accumulation. Petroleum geology is indeed a complex and fascinating subject to many members of our society. We hope that this report results in a better understanding of the petroleum industry.

Gold and Diamonds in Indiana: An Update C12-1988

Introduction: Since its first reprinting in 1963, Willis S. Blatchley's "Gold and Diamonds in Indiana" has been a best seller of the Indiana Geological Survey. Much of the appeal of Blatchley's report derives from the novelty of its topic. Most people do not think of the Midwest as an area in which either gold or diamonds are found. The mention of gold usually brings to mind a grizzled old prospector up a gulch on the back side of some lonely mountain in Colorado or a team of gold seekers along Bear Creek near Dawson, Alaska. Indiana gold, although not plentiful, has been found in sufficient quantities mostly along streams in Morgan and Brown Counties to keep interest in recovering the yellow metal alive for more than 135 years. "Gold and Diamonds in Indiana" has also gained popularity because it was written in 1903---a time when the gold-producing areas of Indiana were relatively unspoiled and scenic and life moved at an enviably slower pace than it does today. Because of the attraction of the original "Gold and Diamonds in Indiana," as much as possible of that manuscript has been preserved. Improvements in our understanding of the origins of gold and diamonds are reflected in a new chapter that treats that subject. Like Mr. Blatchley's original, this report is intended not as a treatise on gold mining in Indiana but as a guide for the amateur gold panner who enjoys nature and the challenge of finding a few grains of gold along one of southern Indiana's scenic-upland streams.

Gold and Diamonds in Indiana C12-1963

For a half century or longer it has been known that free gold in the form of minute grains and flakes occurs in a number of Indiana counties. Within the past few years this gold has been the subject of numerous articles in the newspapers, and public curiosity and at­tention have, therefore, been drawn to it. Many letters and in­quiries relative to it have been received at the office of the State Geologist, and a large number of persons have called there to secure information regarding the distribution and quantity of gold in the State. Moreover, the natives of Brown and Morgan counties have, while washing gold, happened upon a half dozen or more small diamonds, most of which have been found in the past five years. The finding of these has given additional interest to the question, and has led me to prepare the present paper, giving in detail what is known concern­ing the occurrence and distribution of gold and diamonds in the State. In company with Mr. R. L. Royse, of Martinsville, who has given the subject more careful study than any other one man, a spe­cial trip was made in May, 1902, through those portions of Brown and Morgan counties where the most gold is thought to occur. A second trip was made to Morgan County in October of the same year. From the information gathered on these. two trips, as well as from all avail­able printed matter on the subject, the present paper has been pre­pared.

Geology of the Falls of the Ohio River C10-1970

From the Introduction: The Falls of the Ohio River is at the McAlpine Dam between Louis­ville, Ky., and Jeffersonville and Clarksville, Ind. The Falls is essentially within the State of Kentucky, since the state boundary was established along the north bank of the Ohio River, but access to the Falls is now almost exclusively through Jeffersonville. The Falls of the Ohio was a strategic location during the early history of the Midwestern United States, for it was the only place along "La Belle Riviere" that required a portage for boats and served as a natural fording place. Evidence of Indians traveling in the area has been found, especially along the wide path known as the Buffalo Trace that was used by early explorers and animals. The French explorer LaSalle stopped at the Falls in 1669, and George Rogers Clark, enroute to his capture of Kaskaskia and Vincennes, established the first settlement at the Falls in 1771.
