The Impact of Long-Term Glacial Erosion on the Active Chugach-St. Elias Mountains, southern Alaska
… strike, where extensive piedmont glaciers (low equilibrium line altitudes) cover the windward side of the range and small isolated glaciers (high equilibrium line altitudes) occupy the leeward side. If glacial erosion is greatest at the equilibrium line altitude, then glaciers will act as …

Climatic factors influencing Last Glacial Maximum and modern glacial conditions in the tropical and subtropical Andes
… results show average Last Glacial Maximum (LGM) equilibrium line altitude (ELA) depressions to be approximately 600 m in the tropics and 800 m in the subtropics, consistent with studies that suggest the subtropical Andes were glaciated at LGM. While previous studies have found that the …

INVENTORY OF MONGOLIAN GLACIERS FOR THE GLOBAL LAND ICE MEASUREMENTS FROM SPACE (GLIMS) PROGRAM
… this study parameterized the glacier outlines using SRTM data, including equilibrium line altitude, mean slope, mean glacier terminus elevation, and aspect. Including data acquired from ASTER GDEM, this study found that surface lowering occurred on 82.3 % of all glaciers from between 2000 …

Neoglacial climate in the Southern Coast Mountains, British Columbia
… allowed partial quantification of shifts in treeline. Treeline at the site was at least 85 m above the present level from 4800-3800 BP, suggesting that summer temperatures were at least 0.6°C above the present. High treeline until 3800 BP indicates a relatively late date for the …

The interaction of climate, tectonics, and topography in the Olympic Mountains of Washington State: the influence of erosion on tectonic steady-state and the synthesis of the alpine glacial history
… 1963±45, to less than 20±45 years. The estimated equilibrium line altitude (ELA) for Royal Glacier during this time is 1774 m as compared with 1688 m for Blue Glacier in the western Olympics over the same period. A compendium of glacial deposits observed throughout the peninsula is also summarized …

A Thermochronological Investigation of Orogenic Architecture, Kinematics, and Tectonic-Climatic Interactions within the St. Elias Orogen, Alaska
… focused around a narrow zone where the glacial equilibrium line altitude (ELA) intersects mean topography. This zone of rapid exhumation, not present prior to the onset of intense glacial conditions, cuts across the structural trend of the orogen and is more narrowly focused than the zone of …

Reconstructing Loch Lomond Stadial Glaciers and Climate in the south-west English Lake District
… have the potential to significantly raise the equilibrium line altitude (ELA) across a region. This lowers the temperature at the ELA and therefore increases the reconstructed palaeoprecipitation at the ELA. In order to test the viability of the reconstructed glaciers in the Lake District, a 2D …

An Assessment of the Relationship between Glacier Mass Balance and Synoptic Climate in Norway: Likely future implications of climate change.
… Results for the ice-flow model indicate that the equilibrium line altitude (ELA) of Rembesdalskaka is likely to increase in altitude from its average 1968-1997 position of 1650 metres to 1750 metres by end of century resulting in a retreat of front position of nearly 3km. Despite a decreasing …
