The Snowy Day, a 1963 Caldecott Medal winner, is the simple tale of a boy waking up to discover that snow has fallen during the night. Keats's illustrations, using cut-outs, watercolors, and collage, are strikingly beautiful in their understated color and composition.
There are three iron ranges in the Upper Peninsula of Michigan, these are the Gogebic, Marquette and Menominee Ranges. The Gogebic was the last of the three great iron ore fields opened in the Upper Peninsula and northern Wisconsin.
However, its use only became widespread in the 14th century, when smelting furnaces (the forerunner of blast furnaces) began to replace forges. Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe2O3) or magnetite (Fe3O4). About 98% of world iron ore production is used to make iron in the form of steel.
