Extending the Late Holocene White River Ash Distribution, Northwestern Canada STEPHEN D
ARCTIC VOL. 54, NO. 2 (JUNE 2001) P. 157– 161 Extending the Late Holocene White River Ash Distribution, Northwestern Canada STEPHEN D. ROBINSON1 (Received 30 May 2000; accepted in revised form 25 September 2000) ABSTRACT. Peatlands are a particularly good medium for trapping and preserving tephra, as their surfaces are wet and well vegetated. The extent of tephra-depositing events can often be greatly expanded through the observation of ash in peatlands. This paper uses the presence of the White River tephra layer (1200 B.P.) in peatlands to extend the known distribution of this late Holocene tephra into the Mackenzie Valley, northwestern Canada. The ash has been noted almost to the western shore of Great Slave Lake, over 1300 km from the source in southeastern Alaska. This new distribution covers approximately 540000 km2 with a tephra volume of 27 km3. The short time span and constrained timing of volcanic ash deposition, combined with unique physical and chemical parameters, make tephra layers ideal for use as chronostratigraphic markers. Key words: chronostratigraphy, Mackenzie Valley, peatlands, White River ash RÉSUMÉ. Les tourbières constituent un milieu particulièrement approprié au piégeage et à la conservation de téphra, en raison de l’humidité et de l’abondance de végétation qui règnent en surface. L’observation des cendres contenues dans les tourbières permet souvent d’élargir notablement les limites spatiales connues des épisodes de dépôts de téphra. Cet article recourt à la présence de la couche de téphra de la rivière White (1200 BP) dans les tourbières pour agrandir la distribution connue de ce téphra datant de l’Holocène supérieur dans la vallée du Mackenzie, située dans le Nord-Ouest canadien. -

Club Activities
Club Activities EDITEDBY FREDERICKO.JOHNSON A.A.C.. Cascade Section. The Cascade Section had an active year in 1979. Our Activities Committee organized a slide show by the well- known British climber Chris Bonington with over 700 people attending. A scheduled slide and movie presentation by Austrian Peter Habeler unfortunately was cancelled at the last minute owing to his illness. On-going activities during the spring included a continuation of the plan to replace old bolt belay and rappel anchors at Peshastin Pinnacles with new heavy-duty bolts. Peshastin Pinnacles is one of Washington’s best high-angle rock climbing areas and is used heavily in the spring and fall by climbers from the northwestern United States and Canada. Other spring activities included a pot-luck dinner and slides of the American Women’s Himalayan Expedition to Annapurna I by Joan Firey. In November Steve Swenson presented slides of his ascents of the Aiguille du Triolet, Les Droites, and the Grandes Jorasses in the Alps. At the annual banquet on December 7 special recognition was given to sec- tion members Jim Henriot, Lynn Buchanan, Ruth Mendenhall, Howard Stansbury, and Sean Rice for their contributions of time and energy to Club endeavors. The new chairman, John Mendenhall, was introduced, and a program of slides of the alpine-style ascent of Nuptse in the Nepal Himalaya was presented by Georges Bettembourg, followed by the film, Free Climb. Over 90 members and guests were in attendance. The Cascade Section Endowment Fund Committee succeeded in raising more than $5000 during 1979, to bring total donations to more than $12,000 with 42% of the members participating. -

PROTECT YOUR PROPERTY from STORM SURGE Owning a House Is One of the Most Important Investments Most People Make
PROTECT YOUR PROPERTY FROM STORM SURGE Owning a house is one of the most important investments most people make. Rent is a large expense for many households. We work hard to provide a home and a future for ourselves and our loved ones. If you live near the coast, where storm surge is possible, take the time to protect yourself, your family and your belongings. Storm surge is the most dangerous and destructive part of coastal flooding. It can turn a peaceful waterfront into a rushing wall of water that floods homes, erodes beaches and damages roadways. While you can’t prevent a storm surge, you can minimize damage to keep your home and those who live there safe. First, determine the Base Flood Elevation (BFE) for your home. The BFE is how high floodwater is likely to rise during a 1%-annual-chance event. BFEs are used to manage floodplains in your community. The regulations about BFEs could affect your home. To find your BFE, you can look up your address on the National Flood Hazard Layer. If you need help accessing or understanding your BFE, contact FEMA’s Flood Mapping and Insurance eXchange. You can send an email to FEMA-FMIX@ fema.dhs.gov or call 877 FEMA MAP (877-336-2627). Your local floodplain manager can help you find this information. Here’s how you can help protect your home from a storm surge.

February 2021 Historical Winter Storm Event South-Central Texas
Austin/San Antonio Weather Forecast Office WEATHER EVENT SUMMARY February 2021 Historical Winter Storm Event South-Central Texas 10-18 February 2021 A Snow-Covered Texas. GeoColor satellite image from the morning of 15 February, 2021. February 2021 South Central Texas Historical Winter Storm Event South-Central Texas Winter Storm Event February 10-18, 2021 Event Summary Overview An unprecedented and historical eight-day period of winter weather occurred between 10 February and 18 February across South-Central Texas. The first push of arctic air arrived in the area on 10 February, with the cold air dropping temperatures into the 20s and 30s across most of the area. The first of several frozen precipitation events occurred on the morning of 11 February where up to 0.75 inches of freezing rain accumulated on surfaces in Llano and Burnet Counties and 0.25-0.50 inches of freezing rain accumulated across the Austin metropolitan area with lesser amounts in portions of the Hill Country and New Braunfels area. For several days, the cold air mass remained in place across South-Central Texas, but a much colder air mass remained stationary across the Northern Plains. This record-breaking arctic air was able to finally move south into the region late on 14 February and into 15 February as a strong upper level low-pressure system moved through the Southern Plains. As this system moved through the region, snow began to fall and temperatures quickly fell into the single digits and teens. Most areas of South-Central Texas picked up at least an inch of snow with the highest amounts seen from Del Rio and Eagle Pass extending to the northeast into the Austin and San Antonio areas. -
Harmony Ridge-Lucania's Southeast Ridge
Harmony Ridge-Lucania’s Southeast Ridge S t e v e n G a s k il l , Colorado Mountain Club T h E complex massif of Mount Lu- cania rises to 17,147 feet in the St. Elias Mountains, only 50 miles north of Mount Logan. Before we started, no route had yet been completed on its southeast face for obvious reasons. The ridges are all long and draped with hanging glaciers; the faces are forbidding and well fortified. Of the myriad of ridges which make up this side of the mountain, only one goes directly to the summit, the southeast ridge, rising above a tor tured icefall in a perfect line toward the top. This was our objective. Phil Raevsky, Mike Ruckhaus, my brother Craig* and I landed on the upper Dennis Glacier on April 23, a perfect day which allowed us an unsurpassed view of the complex of St. Elias peaks, pinnacles and glaciers and especially of our entire route and planned traverse. We contemplated an alpine-style climb over Mount Lucania, across Mount Steele and finally down Steele’s beautiful east ridge, followed by a 70-mile hike out to the Alaska Highway. The mountain of equipment and food needed for the climb would make us ferry loads, at least up to the summit. By then we hoped to have reduced it to a load apiece. We spent the first day carrying two loads each up the two-and-a-half miles to our first camp, Echo Flats, at the base of the icefall. The worst dangers of the climb start there. -

The recovered dacite tephra correlates with the MEd tephra, whereas many of the rhyolitic Alaska North Pacific Ocean tephras correlate with published MEVF rhyolites. Correlations were based on age constraints and major Cryptotephra oxide compositions of glass shards. In addition to LGM–Holocene macroscopic tephra units, four marine Mt. -
Resedimentation of the Late Holocene White River Tephra, Yukon Territory and Alaska
Resedimentation of the late Holocene White River tephra, Yukon Territory and Alaska K.D. West1 and J.A. Donaldson2 Carleton University3 West, K.D. and Donaldson, J.A. 2002. Resedimentation of the late Holocene White River tephra, Yukon Territory and Alaska. In: Yukon Exploration and Geology 2002, D.S. Emond, L.H. Weston and L.L. Lewis (eds.), Exploration and Geological Services Division, Yukon Region, Indian and Northern Affairs Canada, p. 239-247. ABSTRACT The Wrangell region of eastern Alaska represents a zone of extensive volcanism marked by intermittent pyroclastic activity during the late Holocene. The most recent and widely dispersed pyroclastic deposit in this area is the White River tephra, a distinct tephra-fall deposit covering 540 000 km2 in Alaska, Yukon, and the Northwest Territories. This deposit is the product of two Plinian eruptions from Mount Churchill, preserved in two distinct lobes, created ca. 1887 years B.P. (northern lobe) and 1147 years B.P. (eastern lobe). The tephra consists of distal primary air-fall deposits and proximal, locally resedimented volcaniclastic deposits. Distinctive layers such as the White River tephra provide important chronostratigraphic control and can be used to interpret the cultural and environmental impact of ancient large magnitude eruptions. The resedimentation of White River tephra has resulted in large-scale terraces, which fl ank the margins of Klutlan Glacier. Preliminary analysis of resedimented deposits demonstrates that the volcanic stratigraphy within individual terraces is complex and unique. RÉSUMÉ Au cours de l’Holocène tardif, des matériaux pyroclastiques ont été projetés lors d’importantes et nombreuses éruptions volcaniques, dans la région de Wrangell de l’est de l’Alaska.
