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.
Intensive exploitation began there in the 1950s. Other large iron ore deposits are located in the Kola Peninsula, Karelia, south-central Siberia, and the Far East. The largest copper deposits are located in the Kola Peninsula and the Urals, and lead and zinc are found in North Ossetia.
