Charles Richard Van HiseBorn 29 May 1857; died 19 Nov 1918 at age 61.U.S. geologist who conducted basic geological studies of the Precambrian (570,000,000 to 4,600,000,000 years ago) formations of the Lake Superior region, particularly the iron ores in these formations. These studies were useful for the economic exploitation of the vast iron-ore fields found in that region. He was very interested in, and wrote about, the conservation of natural resources. He regarded soil conservation as "the basal asset of the nation," followed by the "economic mining and use of coal, the conservation of the forests, and the use of metals with the minimum waste." |
