Encyclopedia
Henry Carvill Lewis was an American
geologist
and mineralogist. Lewis was born in Philadelphia and educated at the University of Pennsylvania
. He received his Masters of Arts Degree in 1876 and became attached to the Geological Survey of Pennsylvania in 1879. He served for three years as a volunteer member, and during this term he became greatly interested in the study of glacial
phenomena. In 1880 he was chosen professor of mineralogy
in the Philadelphia Academy of Natural Sciences
, and in 1833 he was appointed to the chair of geology in Haverford College
, Pennsylvania.
During the winters of 1885 to 1887 he studied petrology
under HF Rosenbusch at Heidelberg, and during the summers he investigated the glacial geology of northern Europe
and the British Isles
. His observations in North America
, where he had studied under Professor G.F. Wright
, Professor T.C. Chamberlin and Warren Upham
, had demonstrated the former extension of land-ice, and the existence of great terminal moraine
s.
In 1884 his Report on the Terminal Moraine in Pennsylvania and Western New York was published: a work containing much information on the limits of the North American ice-sheet. In Britain he sought to trace in like manner the southern extent of the terminal moraines formed by British ice-sheets, but before his conclusions were matured he died at Manchester on July 21, 1888. The results of his observations were published in 1894 entitled Papers and Notes on the Glacial Geology of Great Britain and Ireland, edited by Dr HW Crosskey

Geologist
A geologist is a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes and history that has shaped it. Geologists usually engage in studying geology. Geologists, studying more of an applied science than a theoretical one, must approach Geology using...

Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...

Moraine
A moraine is any glacially formed accumulation of unconsolidated glacial debris which can occur in currently glaciated and formerly glaciated regions, such as those areas acted upon by a past glacial maximum. This debris may have been plucked off a valley floor as a glacier advanced or it may have...
