2. Etymology: French, from Old French glacier, "to slip"; from Latin glaciare, "to make" or "to turn into ice".
2. A period when a warmer climate separated two periods of glaciation and displayed a characteristic sequence of changes in vegetation.
The term is used especially for several such periods that occurred during the Pleistocene epoch, lasting from 1.8 million to 10,000 years ago.3. A period of warm climate during the Pleistocene (and earlier glacial epochs) during which continental glaciers retreated to a minimum extent.
Interglacials have been of approximately 10,000 years duration, spaced at approximately 100,000-year intervals over the last 1,000,000 years. The last 10,000 years, or postglacial period, is generally considered to be interglacial.
Located in the Haute-Savoie department, Eastern France, on the northern slope of Mont Blanc massif.
It is formed by the junction of three smaller glaciers and extends a few miles North East of Chamonix. There are deep crevasses and high seracs, "ice needles". The glacier is the second-longest glacier in the Alps, after the Aletsch Glacier (the largest glacier in the Alps, covers more than 120 square kilometers [more than 45 square miles] in southern Switzerland).
2. After a given glacial epoch; especially, the Pleistocene.
3. A reference to, or designating, an epoch after the last Glacial and before the Terrace epoch.
2. Being beneath a glacier; such as, subglacial streams.
2. Formerly beneath a glacier; as, a subglacial deposit.
2. Anything that is believed to have been formerly on the surface of a glacier; such as, superglacial debris.
