RECORD of JÖKULHLAUPS at TULSEQUAH and SALMON GLACIERS, NORTHWESTERN BRITISH COLUMBIA Marten Geertsema, BC Forest Service, Prince George, BC John J
RECORD OF JÖKULHLAUPS AT TULSEQUAH AND SALMON GLACIERS, NORTHWESTERN BRITISH COLUMBIA Marten Geertsema, BC Forest Service, Prince George, BC John J. Clague, Simon Fraser University, Burnaby, BC Abstract Jökulhlaups (glacial outburst floods) from lakes dammed by Tulsequah and Salmon glaciers, northwestern British Columbia, have occurred periodically since the early and middle twentieth century, respectively. The floods commenced after decades of substantial downwasting and retreat of the glaciers from their Little Ice Age maximum positions. We use hydrometric data and other records to reconstruct the times and peak discharges of the floods. Tulsequah Lake, which is dammed by Tulsequah Glacier, and Summit Lake, dammed by Salmon Glacier, initially grew in surface area and volume, but, with continued glacier retreat, they have gradually decreased in size. The first jökulhlaups from these lakes were the largest, and discharges decreased as the lakes diminished in size. Tulsequah Glacier impounds two lakes that have developed at different times as the glacier retreated. Tulsequah Lake formed and began to produce outburst floods approximately a half century before Lake No Lake. Today, Tulsequah Lake is much smaller in size, and produces much smaller floods, than Lake No Lake. As glaciers in northwestern B.C. continue to shrink in response to climate warming, additional glacier-dammed lakes may form. Thus, the hazard of catastrophic outburst floods is expected to continue. Résumé Des jökulhlaups (inondations catastrophiques) résultant de l’effondrement de barrages glaciaires formés par les glaciers Tulsequah et Salmon, situés au nord-ouest de la Colombie-Britannique, se sont produits périodiquement au début et au milieu du vingtième siècle, respectivement. -

Alaska Journal 2007
ALASKA 2007 JOURNAL 2 August 2007 Kathy and I pulled out of the yard at 2:30 p.m. EDT en route to Alaska. She is a little stressed because of so much she wants/has to do at home, but I think after a couple of days on the road, she’ll be fine. The odometer read 23,624. I’m going to make up a daily calendar to record the highlights of each day. The weather is a bit glum, raining slightly as we leave. We have accumulated a 20-inch rainfall deficit through about a week ago, but three days ago the skies opened up and Tallahassee got about 5 to 7 inches of rain, which seems to be continuing. I noticed that Lake Iamonia was bone dry, however, when we passed it. Our plan today is simply to make it to the Atlanta house of Mary Alice Steinheimer, Kathy’s Mom. We drove up Georgia 300 to I-75 and then made it to Kathy’s Mom’s house in Sandy Springs (just north of downtown Atlanta) at about 8:45 p.m. En route my doctor called me and said I had Giardia. He called in a prescription to a Walgreen Pharmacy on Roswell Drive and we picked it up at just before 10:00 p.m. Across the street Kathy, her Mom, and I had a good, but late, supper at the Landmark Diner. The ladies had matzo ball soup and I had eggplant Parmesan with a nice little Greek salad side dish. Kathy and I dropped into bed at about 11:30 p.m. -

Prepared by: Rescan™ Environmental Services Ltd. Vancouver, British Columbia BRUCEJACK GOLD MINE PROJECT 2012 Visual Quality Baseline Report Executive Summary Executive Summary The Brucejack Property is situated within the Sulphurets District in the Iskut River region, approximately 20 kilometres northwest of Bowser Lake or 65 kilometres north-northwest of the town of Stewart, British Columbia. The present report documents baseline studies completed for the project area. The scope of this study was to characterize the current visual condition of the Brucejack Project area. Procedures developed by the British Columbia Ministry of Forests and Range (BC MOFR) are adapted here to guide the collection of visual quality baseline information for the Project. The BC MOFR procedures were developed to take “visual values into account in resource management planning.” In preparation for field work a number of documents and data sources were reviewed. Two land use plans encompass parts of the Project study area. The Cassiar Iskut-Stikine Land and Resource Management Plan (LRMP) includes visual quality as a resource value and identifies and describes areas that are visually sensitive. -

Michaelson Alaska Natural Heritage Program Environment and Natural Resources Institute University of Alaska Anchorage 707 A Street Anchorage, Alaska 99501 National Park Service Alaska Region Inventory & Monitoring Program NPS Report : 2nd Edition, December 2004 Cooperative Agreement No. 1443CA991000013 Funding Source: National Park Service, Inventory & Monitoring Program KLONDIKE GOLD RUSH NATIONAL HISTORICAL PARK VASCULAR PLANT INVENTORY ABSTRACT In 2002 and 2003 the University of Alaska Anchorage, Alaska Natural Heritage Program (AKNHP), conducted vascular plant field inventories in Klondike Gold Rush National Historical Park as part of the Inventory and Monitoring Program of the National Park Service. The primary goal was to document greater than 90% of the vascular plant species expected to occur within the park and significantly improve our understanding of current vascular plant species distributions. The inventory targeted diverse habitat types and poorly sampled areas. The AKNHP visited ten diverse eco-geographic regions and sampled intensively within these regions from mid-June to mid-August, 2002 and early July in 2003. A total of 283 specimens were collected, recorded, pressed, and curated. One hundred seventy four individual taxa are represented, 55 are new records for the park, and an additional ten represent verifications of previously unvouchered reports. The percentage of documented taxa increased from 78% to 86% after the 2002 and 2003 field seasons. A number of finds were range extensions or taxa of conservation concern. Collections were made of the state and globally restricted species: Phyllodoce empetriformis (G4- S1S2 rank) and Eleocharis kamtschatica (G4-S2).
