A formal public hearing will also be held at a County Board meeting to be announced.

  • Discovery & Geology of the Guinness World Record Lake Copper, Lake
    DISCOVERY AND GEOLOGY OF THE GUINNESS WORLD RECORD LAKE COPPER, LAKE SUPERIOR, MICHIGAN by Theodore J. Bornhorst and Robert J. Barron 2017 This document may be cited as: Bornhorst, T. J. and Barron, R. J., 2017, Discovery and geology of the Guinness world record Lake Copper, Lake Superior, Michigan: A. E. Seaman Mineral Museum, Web Publication 2, 8 p. This document was only internally reviewed for technical accuracy. This is version 2 of A. E. Seaman Mineral Museum Web Publication 2 first published online in 2016. The Copper Pavilion at the A. E. Seaman Mineral Museum exhibits a 19-ton mass of native copper recovered on the bottomland of Lake Superior on permanent loan from the State of Michigan, Department of Natural Resources. Discovery This Guinness World Record holding tabular mass of native copper, weighing approximately 19 tons, was recovered from the bottomlands of Lake Superior and is now on exhibit in the Copper Pavilion at the A. E. Seaman Mineral Museum of Michigan Tech referred to here as the "Lake Copper." Figure 1: Location of the Lake Copper shown in context with the generalized bedrock geology along the flank of the Midcontinent rift system (after Bornhorst and Lankton, 2009). 1 It was discovered in July of 1991 by local divers Bob Barron and Don Kauppi on the bottomlands of Lake Superior in about 30 feet of water northwest of Jacob’s Creek, Great Sand Bay between Eagle River and Eagle Harbor (Figure 1 and 2). The tabular Lake Copper was horizontal when discovered rather than vertical in the vein as it had fallen over.

  • Regional Gravity Investigation of the Eastern Portion of the Northern Peninsula of Michigan
    REGIONAL GRAVITY INVESTIGATION OF THE EASTERN PORTION OF THE NORTHERN PENINSULA OF MICHIGAN By Erdogan Oray A THESIS Submitted to Michigan State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Department of Geology 1971 PLEASE NOTE: Some pages may have indistinct print. Filmed as received. University Microfilms, A Xerox Education Company ABSTRACT REGIONAL GRAVITY INVESTIGATION OF THE EASTERN PORTION OF THE NORTHERN PENINSULA OF MICHIGAN By Erdogan Oray A regional gravity investigation was conducted to delineate the Precambrian features of the eastern portion of the Northern Peninsula of Michigan in relation to the tectonic framework of the Lake Superior region and the Southern Peninsula of Michigan. During the survey, an area of 12,000 square miles in the Northern Peninsula of Michigan was covered by a total of 1,003 gravity stations. An additional 851 gravity stations previously observed in the Southern Peninsula of Michigan, Beaver Island, northern Lake Huron, northern Lake Michigan and Sault Ste. Marie area of Canada were used to establish the regional gravity pattern. The Bouguer Gravity Anomaly Map with the aid of a Double Fourier Series Residual Gravity Map indicates that the eastern portion of the Northern Peninsula is associated with two major linear positive gra­ vity anomalies. One of these anomalies trends south from Whitefish Point on the south shore of Lake Superior and is associated with ba­ salts upthrown into a horst within the eastern limb of the Lake Sup­ erior syncline. This anomaly is correlated with the Middle Keweenawan Erdogan Oray volcanics outcropping on Mamainse Point, Ontario.

Due to several factors the town of Pequaming became a "ghost town" in 1942. The factors of location, outside control, resource depletion and changing technology are examined along with alternatives at each stage of development in land use which have arisen since the town was shut down by the Ford Motor Company in a revamping of its holdings. Through several transfers of ownership the property has remained a single holding. A case study approach is used for each ownership period tracing and evaluating actual and proposed development to date. An image-plan model is used in the case study. It essentially tries to determine the plans and goals of the various owners in regard to the site initially, the resources they saw avail- able, methods used by them, and the degree of their success Joseph Lewie Lepczyk with respect to the initial plans and goals. Special atten- tion has been directed to accessing the recreational de- velopment potential of the site at this time.
