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.
Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) and magnetite (Fe3O4). These iron ores have been mined to produce almost every iron and steel object that we use today - from paper clips to automobiles to the steel beams in skyscrapers.
