south cascade glacier altitude

Above Mark Meier initially selected South Cascade for long-term study in 1958 after reviewing a number of other candidate glaciers. The altitude at this point on the glacier is about 6200 feet. Steady state glacier = ~65% accum area What are the consequences of a rise or fall of the ELA? For both the June and August measurements we then calculate snow water equivalent. Altitude: 3 285 m, Mont Baker ... Il s'agit de montagnes principalement non volcaniques mais qui incluent les stratovolcans du mont Baker et du pic Glacier, qui font partie de l'arc volcanique des Cascades (en anglais : Cascade Volcanic Arc). The area of the glacier is about 69 . The North Cascade Range in the vicinity of South Cascade Glacier accumulated smaller than normal winter snowpacks during water years 2004 and 2005. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. South Cascade Glacier (lat 48'22' N., 1,900-m mean equilibrium line altitude) had a winter balance of 3.28 m, slightly above average. South Cascade Glacier in Washington documented from 1928 to 2003 showing the recent rapid glacier retreating. It is not known, however, how representative South Cascade Glacier is of NOCA glaciers in general because of the influence of non-climatic factors such as geographic position, aspect and elevation. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. The gently sloping glacier surface has an altitude range of 1600– 2100 m over a 3 km centerline length (Figure 1). Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. This kind of retreating is the result of climate change which has significantly increased due to … Lyman Glacier, Highline Trail, Yakima County, Washington, USA - Visualisation et partage de cartes topographiques gratuites. Contour map of South Cascade Glacier, Washington, U.S.A., from the United States Geologic Survey Dome Peak 7.5′ quadrangle. Accordingtothe map, theglacier was field-checkedin1965. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield Research Program (JIRP; Pelto and others, 2013). Graphs showing air temperature near South Cascade Glacier during the 2001 water year..... 21 Figure 11. Snow depths at South Cascade Glacier, May 9, 1997 ..... 23 5. Seasonal mass balance has been monitored at this ablation stake site since 1957. Correspondingly, the balance years 2004 and 2005 maximum winter snow balances of South Cascade Glacier, 2.08 and 1.97 meters water equivalent, respectively, were smaller than the average of such balances since 1959. It spans 1300 m of elevation, from 1160 to 2470 m. The glacier is in a 31.5 km 2 basin and in 2016 it had an area of 16.0 km 2 (O'Neel et al, 2019). Direct field measurements are combined with weather data and imagery … In recent times South Cascade Glacier shows evidence of advances in 2700-2900 B.C., the 16th century, and the middle and late 19th century (Meier, 1964). Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield Research Program (JIRP; Pelto and others, 2013). at South Cascade Glacier by US Geological Survey (USGS), and globally. 3. The average thickness of South Cascade Glacier was found to be 83 meters in 1965, based on flow velocity and balance measurements. This fits well the observations of density of South Cascade Glacier, which for early June of 1993 –1998 yielded a density range of 0.51–0.55 g/cm 3 (Krimmel, 1998). The South Cascade Glacier annual balance in 1966 (-0.94 m) was considerably more negative mainly owing to the deficient winter snowpack (the late-winter balance was only 2.52 m) and the warm dry summer. Mark Meier initially selected South Cascade for long-term study in 1958 after reviewing a number of other candidate glaciers. : I 19.16:715-B 1. This glacier is 0.5 km long and covers an area of 0.2 km 2; the mean ELA (equilibrium line altitude) is 3,650 m. Runoff from the 0.97 km 2 basin flows into the Tuolumne River, which flows west into the San Joaquin Valley of California. South Cascade Glacier has the longest history of mass balance measurements in North America and second longest in the world after Storglaciären in Sweden. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago. > South Cascade Glacier Click on the map to display elevation . 1). Figure 2. Snow, ice, and water balances, South Cascade Glacier, 1965 hydrologic and balance years_ 3. The altitude at this point on the glacier is about 6200 feet. This valley glacier occupies roughly … Near the glacier terminus, 5 to 6 m of combined snowmelt and ice-melt was measured during the summer. High Altitude Weather Station Data at USGS Benchmark Glaciers ... Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005.

Instrumentation at South Cascade Glacier during the 1965 hydrologic year_____ _ _____ A13 2. Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. We turned back to Kenmore many times when The theoretical pattern compares well, in a broad sense, with the flow pattern determined from tracer injections in 1986 and 1987. For glaciers such as South Cascade Glacier, Washington, and Gulkana Glacier, Alaska, the balance-altitude function reaches a maximum at an altitude lower than the head of the glacier, then decreases slightly at higher altitudes (Meier and others, 197 I), This decrease can be explained, at least partiall y, by accumulation processes. 6. glaciers is needed. It ranges in elevation from 1630 to 2100 m a.s.I., and its equilibrium-line elevation is at approximately 1870 m a.s.l. Maclure Glacier (lat 37O45' N., 3,650-m (metres) mean equilibrium line altitude) had an above normal winter balance of 3.46 m and a positive annual balance of 1.05 m (metres of water equivalent). Columbia Glacier is a large (1,100 square kilometers), multi-branched calving glacier in south central Alaska that flows mostly south out of the Chugach Mountains to its tidewater termination in Prince William Sound. Our Research: Our group studies mass change at five glaciers (Gulkana, Lemon Creek, South Cascade, Sperry, Wolverine) in North America using field and remote sensing techniques.To do so, we measure snow accumulation and snow and ice melt at specific locations on the glaciers, then extrapolate those point observations across the entire glacier surface. Fig. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Results at Mount Rainier also reflect the broader shrinking trends, with the lower-elevation glaciers being particularly hard hit. Change in glacier volume, ΔV, derived from mass balance measurements on 37 glaciers in five regions in the Northern Hemisphere in recent decades, and a global average. Elevation Range: Approximately 1640-2300 meters. 1. (a) All glaciers are in Queen Elizabeth Islands (Arctic Canada). In glacier: Mass balance of mountain glaciers …the temperate, maritime glaciers is South Cascade Glacier, in western Washington.Its activity index is high, normally about 17 millimetres per metre (0.2 inch per foot); the yearly snow accumulation averages about 3.1 metres of water-equivalent; and the equilibrium line is at the relatively low altitude of 1,900 metres. The terminal moraine is covered by MA. South Cascade Glacier. South Cascade Glacier is a temperate mountain glacier located in the Cascade Mountains, Washington. Glaciers are a defining feature of MORA; as of 1994 there were 27 major glaciers on Mount Rainier with a combined area of 90 km. The glaciers on Mount Rainier decreased in area by 21% between 1913 and 1994 (Nylen, 2004). At the same time that South Cascade Glacier was gaining mass in the early 1970s, Wolverine Glacier was losing mass. It is bordered on the east by 8,261-foot (2,518 m) Sentinel Peak, and is about 17 mi (27 km) north of Glacier Peak in the Glacier Peak Wilderness.Meltwater from the glacier flows directly into South Cascade Lake, which feeds the South Fork Cascade River, which is a tributary of the Skagit River. ... and the input point measurements and elevation data used for these calculations. 3. Ice ablation averaged about 44 mm of water per day during the melt season. Since mass balance measurements began in 1958, 28 years have had negative balances. This glacier has been classified as one of the ‘reference glaciers’ by the World Glacier Monitoring Service because it has received continuous long-term observations dating back to the year 1952/53. Gulkana Glacier (lat 63°15' N., long 145°28' W., fig 7) is a branched valley glacier on the south flank of the Alaska Range. South Cascade Sperry Wolverine. The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon.They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California.Each more than 10,000 feet (3,000 m) in elevation, they are the third-, fourth- and fifth-highest peaks in Oregon. At the same time that South Cascade Glacier was gaining mass in the early 1970s, Wolverine Glacier … It has an altitude range 1630^ 2130mandanareaof2.0km2.Mostprecipitationonthegla-cier falls as snow, withº3m accumulating each winter at the head of the glacier. South Cascade Glacier (Fig. The results confirm stake measurements at South Cascade Glacier in the North Cascades, showing significant loss over the past 60 years. 2010). South Cascade Glacier lost mass at an almost constant rate during the late 1950s to the late 1960s, then gained mass until 1976, and has been losing mass at a fairly constant and rapid rate since 1977. South Cascade Glacier has been in general re-treat since the late 19th century (Miller 1968), and has lost more than one-half its volume during that time. The glacier is in a north-northwest facing valley with an altitude range of 1600–2100 meters (Bidlake et al. Air temperature at 1,615 meters altitude, South Cascade Glacier Basin: a. DESCRIPTION. Coordinates: 47.82698 -123.32662 47.82708 -123.32652 - Minimum elevation: 1,080 m - Maximum elevation: 2,168 m - Average elevation: 1,643 m Meltwater from the glacier flows into South Cascade Lake, the headwaters of the South Fork of the Cascade River. Above 2,100-m altitude, the snowpack accumulated intermittently throughout the summer and a summer surface formed in July during short periods of melting. DESCRIPTION. Direct field measurements are combined with weather data and imagery analyses to estimate the seasonal and annual mass balance at each glacier in both a conventional and reference surface format (Cogley and others, 2011). South Cascade Glacier in Washington experiences some of the highest precipitation levels in the lower 48 states of the USA, exceeding 4500mm per annum in some places. Trees grow on slopes above the accumulation area of this glacier. TABLE 1. Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers.

South Cascade Glacier lost mass at an almost constant rate during the late 1950s to the late 1960s, then gained mass until 1976, and has been losing mass at a fairly constant and rapid rate since 1977. Rugged topography surrounds the glacier, with relief exceeding 1500 m and peaks reaching 2400 m elevation. La partie située au Canada est appelée Cascade Mountains par les Canadiens [1] et Canadian Cascades par les habitants des États-Unis. Suba sa yelo ang South Cascade Glacier sa Tinipong Bansa. South Cascade Glacier for four different years between 1964 and 1992, during which the glacier was thinning and receding. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield Research Program (JIRP; Pelto and others, 2013). The main trunk of the glacier has a southerly aspect, and is fed by four cirques with west, south, and east aspects. South Cascade Glacier (48.36‡ N, 121.06‡ W) is a small, north-facing, temperate glacier on the crest of the North Cascade Range of northwesternWashington, 250km from the Pacific Ocean (Fig. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. €A Kenmore Air Harbor Beaver after landing on South Cascade Glacier and poised to take off down glacier. Differences between the patterns may result from the routing of surface meltwater in crevasses prior to entering the body of the glacier. The purpose of this report is to describe and summarize data collected during the 2011 water year. High-altitude measurements of meteorological data have been collected since the [...]. 3) is located in the North Cascades of Washington. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. The 2004 glacier summer … Direct field measurements are combined with weather data and imagery analyses to estimate the seasonal and annual mass balance at each glacier in both a conventional and reference surface format (Cogley and others, 2011). The well-studied South Cascade Glacier shrank by 22% during this time period (USGS), while the Blue Glacier in Olympic National Park saw a terminus retreat of 2% between 1957 and 1997 (Conway et al., 1999).
