Gold diggers : striking it rich in the Klondike
No event in our history is more legendary than the Yukon Gold Rush of 1896. On August 16, when rich gold deposits were discovered in Bonanza Creek, 100,000 prospectors set off for the newly created Dawson City in search of instant wealth. Hungry miners hoped for the one big strike; others, for prosperity in this instant boom town; some, for the adventure of a lifetime. Charlotte Gray, one of our best writers of non-fiction, tells the story of the Gold Rush through the intimate lives of six extraordinary people: the saintly priest Father Judge; the feisty entrepreneur Belinda Mulrooney; the struggling writer Jack London; the imperious British journalist Flora Shaw; the legendary Sam Steele of the Mounties; and the prospector William Haskell. Brilliantly interweaving their stories, Gray creates a fascinating panorama of a frontier town where desperados, saloon keepers, gamblers, dance hall girls, churchmen and law-makers were thrown together in a volatile time. Beautifully illustrated with period photographs and documents of the Gold Rush, Gold Diggers is a colourful and entertaining journey into a world gone mad for gold.
Gamblers and Dreamers
Gamblers and Dreamers tackles some of the myths about the history of the North in the era of the gold rush.
North to Benjamin
Eleven-year-old Edgar and his mother move to Dawson, a town in Yukon, Canada, for a new start, but when Edgar fears his mother's destructive behavior will force them to leave, he turns to a dog named Benjamin to help him stop the worst from happening.
Nitrogen isotopes suggest a change in nitrogen dynamics between the Late Pleistocene and modern time in Yukon, Canada
A magnificent repository of Late Pleistocene terrestrial megafauna fossils is contained in ice-rich loess deposits of Alaska and Yukon, collectively eastern Beringia. The stable carbon (δ13C) and nitrogen (δ15N) isotope compositions of bone collagen from these fossils are routinely used to determine paleodiet and reconstruct the paleoecosystem. This approach requires consideration of changes in C- and N-isotope dynamics over time and their effects on the terrestrial vegetation isotopic baseline. To test for such changes between the Late Pleistocene and modern time, we compared δ13C and δ15N for vegetation and bone collagen and structural carbonate of some modern, Yukon, arctic ground squirrels with vegetation and bones from Late Pleistocene fossil arctic ground squirrel nests preserved in Yukon loess deposits. The isotopic discrimination between arctic ground squirrel bone collagen and their diet was measured using modern samples, as were isotopic changes during plant decomposition; Over-wintering decomposition of typical vegetation following senescence resulted in a minor change (~0-1 ‰) in δ13C of modern Yukon grasses. A major change (~2-10 ‰) in δ15N was measured for decomposing Yukon grasses thinly covered by loess. As expected, the collagen-diet C-isotope discrimination measured for modern samples confirms that modern vegetation δ13C is a suitable proxy for the Late Pleistocene vegetation in Yukon Territory, after correction for the Suess effect. The N-isotope composition of vegetation from the fossil arctic ground squirrel nests, however, is determined to be ~2.8 ‰ higher than modern grasslands in the region, after correction for decomposition effects. This result suggests a change in N dynamics in this region between the Late Pleistocene and modern time.
Palynological Evidence for a Warmer Boreal Climate in the Late Pliocene of the Yukon Territory, Canada
The Late Pliocene (3.6–2.6 Ma) was a period of significant global warmth, considered a potential analogue for future anthropogenic climate change. Newly discovered fine-grained sediments from between the gold-bearing lower and upper White Channel Gravels show the presence of a wetland or lake within Bonanza Creek, Dawson Mining District, Yukon. This environment was surrounded by a diverse Pinaceae-dominated boreal forest with significant stands of angiosperms in favourable sites. Quantitative climate reconstructions derived from pollen and spores reveal a mean annual temperature at least 6 °C warmer than today with warm summers and relatively mild winters. Finally, the new pollen assemblage is used to discuss the age of the White Channel Gravels.
Evidence for Human Modification of a Late Pleistocene Bison (Bison sp.) Bone from the Klondike District, Yukon Territory, Canada
A 31 000 BP bison limb bone from Nugget Gulch near Dawson City, Yukon, shows a \"ring crack\" considered to be a human-made impact mark resulting in exposure of marrow. This bone is approximately contemporaneous with wolf, horse, and Dall sheep specimens found on an ancient Mid-Wisconsinan terrain surface at this locality. Similar ring cracks, also interpreted as human-made, have been noted on late-glacial bison bones from Engigstciak, Yukon, and Lost Chicken Creek, Alaska. /// Un os de membre de bison datant de 31 000 ans av. J.-C. et provenant de Nugget Gulch près de Dawson City au Yukon, montre une \"fissure circulaire\" que Ton considère être la marque d'un impact donné par un être humain pour mettre la moelle à nu. Cet os est à peu près contemporain de spécimens provenant de loups, de chevaux et de mouflons de Dall trouvés au même endroit, à la surface d'un ancien terrain datant du milieu du wisconsinien. On a remarqué des fissures circulaires semblables, que l'on a aussi interprétées comme découlant d'une action humaine, sur des os de bison du tardiglaciaire trouvés à Engigstciak au Yukon et à Lost Chicken Creek en Alaska.
Estimation of Yukon River discharge during an ice jam near Dawson City
The paper presents two approaches used independently to estimate river discharge during an ice jam on the Yukon River near Dawson City. One method entailed the use of large-scale particle image velocimetry to obtain surface velocities, which were extrapolated and integrated to yield a discharge. Videotaping of ice-floe drift comprised the measurement method used for the large-scale particle image velocimetry. The second approach entailed numerical simulations performed with a 1-D ice-jam profile model (ICEJAM). The numerical model incorporates an \"island-compensation\" technique developed to take into account the difficulty of using 1-D ice-jam profile models to simulate accurately channels with two-dimensional features such as islands and bars. The two approaches yielded closely comparable estimates of river discharge.Key words: discharge, velocity, measurement, river, ice, jam, particle, image, velocimetry, islands.
