The 2020 Elliot Creek landslide-tsunami-flood cascade originated from an 18.3 Mm 3 rock slope failure in quartz diorite bedrock a valley undergoing rapid glacial retreat. We used airborne LiDAR and optical imagery to characterize the its surroundings. Using LiDAR, we determined that two rockslides (2020 older undated one) occurred on this shared common basal rupture surface. mapped main sets of...

Barhal Valley belongs to the Çoruh System in Kaçkar Mountains of northeastern Anatolia. This 13 km long valley is located south main weather divide and east Mt. Kaçkar, with highest peak mountain range being 3932 m. Today, source an average yearly precipitation 2000 mm moisture Black Sea, situated approximately 40 north study site. Glaciers Last Glacial Maximum (LGM) descended directly from rea...

Mountain-range topography is determined by the complex interplay between tectonics and climate. However, often it is not clear to what extent climate forces topographic evolution and how past climatic episodes are refl ected in present-day relief. The Andes are a tectonically active mountain belt encompassing various climatic zones with pronounced differences in rainfall, erosion, and glacier e...

Abstract In 1890, former students of Arnold Guyot at the University Neuchàtel dedicated a ‘large glacial boulder from Neuchâtel’ to his memory, now in front Hall Princeton University. We established that this block originated with all certainty Upper Carboniferous conglomerates Salvan–Dorénaz Basin, relics which crop out Alps western Switzerland and eastern France. During Last Glacial Maximum, ...

Introduction: Basal-ice and surface-ice temperatures are key parameters governing the style of glacial erosion and deposition. Temperate glaciers contain basal ice at the pressure-melting point (wet-based) and commonly exhibit extensive areas of surface melting. Such conditions foster basal plucking and abrasion, as well as deposition of thick matrix-supported drift sheets, moraines, and glacio...

Sharp-crested moraines, up to 120 m high and 9 km beyond Little Ice Age glacier limits, record a late Pleistocene advance of alpine glaciers in the Finlay River area in northern British Columbia. The moraines are regional in extent and record climatic deterioration near the end of the last glaciation. Several lateral moraines are crosscut by meltwater channels that record downwasting of trunk v...

Contemporary equilibrium-line altitudes (ELAs) for glaciers in the high mountains of the Himalaya and Tibet have considerable variation because the region is influenced by two major climatic systems (the mid-latitude westerlies and the south Asian summer monsoon) and glaciers are subject to strong topographic controls. Reconstructions of past ELAs based on the former extent of glaciers are nume...
