An Overview of World-Class Gold Districts in Canada's Newest
JULY 2002 Issue 74 An Overview of World-Class Gold Districts in Canada’s Newest Territory – Nunavut Rob Carpenter Indian and Northern Affairs Canada PO Box 100, Iqaluit, Nunavut, X0A 0H0 Email [email protected] Introduction The Lupin Mine is currently Nunavut’s sole gold producer and has poured over 3 million ounces of bullion since production began in 1982 (Fig. 1). However, recent gold exploration activities across Nunavut have resulted in several significant discov- eries which are at, or approaching, feasibil- ity. This renewed interest in gold explora- tion in Canada’s north is largely due to the availability of extensive, under-explored land parcels that are capable of hosting near-surface and high-grade gold deposits. Acquiring these large land parcels also im- proves the overall effectiveness of explora- tion and increases the chance of discover- ing much sought after gold “districts”, such as the well known Timmins and Kirkland Lake gold districts of the Archean Superior Province. Emerging gold districts in Nunavut in- clude: the Hope Bay Project, located in the northern part of the Archean Slave Prov- ince; the Meadowbank Project, and; the Meliadine Project, both located in the Ar- chean Western Churchill Province (Fig. 1).

Proceedings of the Indiana Academy of Science
Relative Location and the Growth of Terre Haute Thomas Frank Barton, Indiana University A population graph of Terre Haute presents a challenging problem because it is the only large city in Indiana whose population declined for two decades and whose total estimated population in 1950 is less than its peak was in 1920. The city's most rapid growth took place be- tween 1900 and 1910 when its population increased from 36,673 to 58,157. In 1920 its population reached a peak of 66,083 and then declined to 62,810 in 1930 and 62,693 in 1940. A preliminary release indicates that Terre Haute's numbers increased to 64,097 in 1950, a gain of only about 1,400. These statistics stimulate one to ask questions. Why did the city grow so rapidly between 1900 and 1910? What factors contributed to the decline between 1920 and 1940? What are the future prospects? etc. Perhaps in the past too many of those who have been both economically and academically interested in Terre Haute's growth have concentrated their attention upon the political city and have failed to give adequate consideration to its relative location and its neighbors. There are many large and small cities near this Queen City of the Wabash. Approximately 170 miles to the north is Chicago and 100 miles to the south is Evansville. Seventy-three miles to the northeast is Indianapolis, capital of Indiana, while 130 miles to the northwest is Springfield, capital of Illinois. It is interesting to note that Terre Haute is almost equidistant from the metropolitan areas of Chicago, St. -
The Dual Origin of Minnesota
Library of Congress The dual origin of Minnesota / THE DUAL ORIGIN OF MINNESOTA.* BY SAMUEL M. DAVIS. * Read at the monthly meeting of the Executive Council, April 10, 1899. It is the purpose of this paper to trace the origin and source of the territory now comprised within the boundary of the state of Minnesota This state occupies the unique position of being the only state in the Union which acquired its territory from the two largest accessions of land to the United States in the early history of this government. I refer to the cession of the Northwest Territory by Great Britain in 1783 and the Louisiana Purchase in 1803. About twenty-nine thousand square miles of territory, including all east of the Mississippi which is now comprised within the boundary of the state, originated in the cession by the treaty with Great Britain in 1783. The remaining part, about fifty-five thousand square miles, was secured from the territory originally purchased from France in 1803. It is my object to sketch the main features connecting these two great treaties of accession of territory, both in relation to the boundary of the territory acquired and also with reference to the government provided for them after the territory was acquired. CESSION OF THE NORTHWEST TERRITORY. The Revolutionary War, which began April 19th, 1775, was closed by three separate treaties of peace. The United States and France conducted simultaneous negotiations with different English Commissioners, with the understanding that the preliminaries should be signed the same day. Dr. Franklin wrote to Vergennes on the 29th of November, 1782, that the American articles were already agreed upon and that he hoped to lay a copy of them before his Excellency the following day. -

Glimpses of Early Dickinson County
GLIMPSES OF EARLY DICKINSON COUNTY by William J. Cummings March, 2004 Evolution of Michigan from Northwest Territory to Statehood From 1787 to 1800 the lands now comprising Michigan were a part of the Northwest Territory. From 1800 to 1803 half of what is now the Lower Peninsula of Michigan and all of the Upper Peninsula were part of Indiana Territory. From 1803 to 1805 what is now Michigan was again part of the Northwest Territory which was smaller due to Ohio achieving statehood on March 1, 1803. From 1805 to 1836 Michigan Territory consisted of the Lower Peninsula and a small portion of the eastern Upper Peninsula. In 1836 the lands comprising the remainder of the Upper Peninsula were given to Michigan in exchange for the Toledo Strip. Michigan Territory Map, 1822 This map of Michigan Territory appeared in A Complete Historical, Chronological and Geographical American Atlas published by H.S. Carey and I. Lea in Philadelphia in 1822. Note the lack of detail in the northern Lower Peninsula and the Upper Peninsula which were largely unexplored and inhabited by Native Americans at this time. Wiskonsan and Iowa, 1838 Michigan and Wiskonsan, 1840 EXTRA! EXTRA! READ ALL ABOUT IT! VULCAN – A number of Indians – men, women and children – came into town Wednesday last from Bad Water [sic] for the purpose of selling berries, furs, etc., having with them a lot of regular Indian ponies. They make a novel picture as they go along one after the other, looking more like Indians we read about than those usually seen in civilization, and are always looked upon in wonderment by strangers, though it has long since lost its novelty to the residents here. -
Carbon Storage and Potential Methane Production in the Hudson Bay Lowlands Since Mid-Holocene Peat Initiation
ARTICLE Received 28 Aug 2013 | Accepted 9 May 2014 | Published 11 Jun 2014 DOI: 10.1038/ncomms5078 Carbon storage and potential methane production in the Hudson Bay Lowlands since mid-Holocene peat initiation Maara S. Packalen1, Sarah A. Finkelstein2 & James W. McLaughlin3 Peatlands have influenced Holocene carbon (C) cycling by storing atmospheric C and releasing methane (CH4). Yet, our understanding of contributions from the world’s second largest peatland, the Hudson Bay Lowlands (HBL), Canada, to peat-climate-C-dynamics is constrained by the paucity of dated peat records and regional C-data. Here we examine HBL peatland development in relation to Holocene C-dynamics. We show that peat initiation in the HBL is tightly coupled with glacial isostatic adjustment (GIA) through most of the record, and occurred within suitable climatic conditions for peatland development. HBL peatlands initiated most intensively in the mid-Holocene, when GIA was most rapid and climate was cooler and drier. As the peat mass developed, we estimate that the HBL potentially released 1–7 Tg CH4 per year during the late Holocene. Our results indicate that the HBL currently stores a C-pool of B30 Pg C and provide support for a peatland-derived CH4 contribution to the late Holocene atmosphere. 1 Department of Geography, University of Toronto, Toronto, Ontario, Canada M5S 3G3. 2 Department of Earth Sciences, University of Toronto, Toronto, Ontario, Canada M5S 3B1. 3 Ontario Forest Research Institute, Ontario Ministry of Natural Resources, Sault Ste.

Historica Canada Education Portal Joseph Tyrrell
Historica Canada Education Portal Joseph Tyrrell Overview This lesson is based on viewing the J.B Tyrrell biography from The Canadians series. Tyrrell was an important geological surveyor for the Canadian government in the late nineteenth century. Among his many achievements, he mapped the North, discovered coal, and the remains of what became known as the Albertasaurus. Aims Although there is now a museum in Tyrrell's honour, he was not recognized for his achievements in his lifetime. Students will research Tyrrell's achievements, using both primary and secondary sources, and assess the importance of his discoveries. Background In 1884, Joseph Tyrrell, geological surveyor for the Government of Canada, led a small group of explorers and cartographers into Alberta's badlands. There he made the major discovery of his life: the remains of a 6,000 year old dinosaur – the Albertasaurus. Unfortunately, he was denied the recognition for this discovery and this became a metaphor for his life. The man whose mission was to chart the unknown felt overlooked and misunderstood himself. Joseph Burr Tyrrell was born in Weston, Ontario, on 1 November 1858. He witnessed Canada's Confederation as a young boy in Toronto, and even though he was small and sickly, he caught the fever of a new country and dreamed about a life of adventure and exploration. His dream would come true as a geological surveyor for the Canadian government and his work took him to the uncharted wilds of Canada. He mapped the Great Plains of Alberta, and later the Northwest Territories, which were so unknown at the time that they were thought to be inhabited by cannibals. -
