Abstract Comparison of historic maps and aerial and ground-based photographs for the small cirque glaciers and glacierets of Rocky Mountain National Park in the northern Front Range of Colorado, USA, indicates modest change during the 20th century. The glaciers retreated through the first half of the 20th century, advanced slightly from the mid-1940s to the end of the century and have retreated slightly since. High interannual variability in area and temporal gaps in data complicate the trends… Expand
Twentieth Century Glacier Change on Mount Adams, Washington, USA
Abstract Mount Adams is a large glacier-clad stratovolcano located in southern Washington, USA. We examined the area change of the 12 glaciers on the mountain during the 20th century using historicalExpand
Mass balance of a cirque glacier in the U.S. Rocky Mountains
Glacier National Park, Montana, USA, contains 27 cirque glaciers, most less than 1 km and together comprising about 17 km. These glaciers lie at relatively low elevation (2000 – 3000 m a.s.l.) andExpand
Nine decades of glacier change in the Canadian Rocky Mountains.
Glaciers adjust their physical properties to changes in climate, but long records of glacier change needed to examine this relation are spatially and temporally limited. I determined changes inExpand
Area change of glaciers in the Canadian Rocky Mountains, 1919 to 2006
Glaciers in the Canadian Rocky Mountains con- stitute an important freshwater resource. To enhance our understanding of the influence climate and local topogra- phy have on glacier area, largeExpand
20th Century Retreat and Recent Drought Accelerated Extinction of Mountain Glaciers and Perennial Snowfields in the Trinity Alps, California
Abstract The Trinity Alps is a compact glaciated subrange of the Klamath Mountains in northwest California with elevations < 2,750 m making it a unique location in the western US to study glacierExpand
A century of glacier change in the Wind River Range, WY
Abstract The Wind River Range spans roughly 200 km along the continental divide in western Wyoming and encompasses at least 269 glaciers and perennial snowfields totaling 34.34 ± 0.13 km 2 (2006),Expand
Topographic influences on recent changes of very small glaciers in the Monashee Mountains, British Columbia, Canada
Abstract An analysis of the local topographic setting of very small (<0.4 km2) glaciers within a small region of the Monashee Mountains, British Columbia, was conducted to investigate its influenceExpand
An inventory and topographic analysis of glaciers in the Torngat Mountains, northern Labrador, Canada
This study presents the first complete glacier inventory of the Torngat Mountains, northern Labrador, Canada. In total, 195 glaciers and ice masses are identified, covering a total area of 24.5�1.8Expand
Accelerated loss of alpine glaciers in the Kodar Mountains, south-eastern Siberia
The recession of mountain glaciers around the world has been linked to anthropogenic climate change and small glaciers (e.g. < 2 km2) are thought to be particularly vulnerable, with reports of theirExpand
Glacier change in western North America: influences on hydrology, geomorphic hazards and water quality
The glaciers of western Canada and the conterminous United States have dominantly retreated since the end of the Little Ice Age (LIA) in the nineteenth century, although average rates of retreatExpand


Glacier change (1958-1998) in the North Cascades National Park Complex, Washington, USA
The spatial characteristics for all glaciers in the North Cascades National Park Complex, USA, were estimated in 1958 and again in 1998. The total glacier area in 1958 was 117.3 � 1.1 km 2 ; by 1998Expand
Satellite Image Atlas of Glaciers of the World
Svalbard, Norway, an archipelago in the North Atlantic Ocean (74° to 81° N. lat), has a total area of 62,248 square kilometers, mostly contained in the four main islands, Spitsbergen, Nordaustlandet,Expand

The relation between changes in modern glaciers, not including the ice sheets of Greenland and Antarctica, and their climatic environment is investigated to shed light on paleoglacier evidence ofExpand
Climate change in the Colorado Rocky Mountains: free air versus surface temperature trends
A high elevation data set of surface temperatures from the Front Range of the Rocky Mountains in Colorado, USA, is analysed for evidence of long-term change (1952–98). Sites range from the highExpand
A Comparison of Free-Air and Surface Temperature Trends at High Elevations in the Mountainous West of the U . S .
Concern over the impact of global warming at high elevation sites has increased over the last few years, leading to recent international workshops (e.g., HIGHEST II, 2001) and the declaration by theExpand
Spatial and morphological change on Eliot Glacier, Mount Hood, Oregon, USA
Abstract Eliot Glacier is a small (1.6 km2) glacier on Mount Hood, Oregon, USA, and its ablation zone is largely covered with rock debris. We examine the interrelated processes of ablation rates, iceExpand
Parallax measurements on matching aerial photograph stereopairs from 1958 and 1983 were used to calculate the ice lost from Dinwoody Glacier in the Wind River Range of Wyoming. The ice remaining inExpand
Changes in climate and hydrochemical responses in a high-elevation catchment in the Rocky Mountains, USA
A continuous climate record since 195 1 at Niwot Ridge in the Colorado Front Range shows a decline in mean annual temperature, an increase in annual precipitation amount, and a decrease in mean dailyExpand
Spatial Snow Modeling of Wind-Redistributed Snow Using Terrain-Based Parameters
Abstract Wind is widely recognized as one of the dominant controls of snow accumulation and distribution in exposed alpine regions. Complex and highly variable wind fields in rugged terrain lead toExpand
