Q:Information:  - Rodney Earland `` Rod '' Paavola ( b. August 21 , 1939 in Hancock , Michigan - d. December 3 , 1995 ) was an American ice hockey player . He won a gold medal at the 1960 Winter Olympics .  - A medal or medallion is, strictly speaking, a small, flat, and round (at times, ovoid) piece of metal that has been sculpted, molded, cast, struck, stamped, or some way marked with an insignia, portrait, or other artistic rendering. A medal may be awarded to a person or organization as a form of recognition for sporting, military, scientific, academic, or various other achievements. Military awards and decorations are more precise terms for certain types of state decoration. Medals may also be created for sale to commemorate particular individuals or events, or as works of artistic expression in their own right. In the past, medals commissioned for an individual, typically with their portrait, were often used as a form of diplomatic or personal gift, with no sense of being an award for the conduct of the recipient.  - A gold medal is a medal awarded for highest achievement in a non-military field. Its name derives from the use of at least a fraction of gold in form of plating or alloying in its manufacture.  - Hancock is a city in Houghton County, Michigan, United States and is located on Copper Island, which is part of the Keweenaw Peninsula, on the Keewenaw Waterway directly opposite Houghton, Michigan. The population was 4,634 at the 2010 census.  - Copper Island is a local name given to the northern part of the Keweenaw Peninsula (projecting northeastward into Lake Superior at the western end of the Upper Peninsula of Michigan, United States of America), separated from the rest of the Keweenaw Peninsula by Portage Lake and the Keweenaw Waterway.  - The International Olympic Committee (IOC; French: Comité international olympique, CIO) is the supreme authority of the worldwide Olympic movement. It is an international, non-profit, non-governmental organization based in Lausanne, Switzerland. Its mission is enshrined in the Olympic Charter: to support the development of competitive sport by ethical and environmentally sustainable means.  - The 1960 Winter Olympics was a winter multi-sport event held between February 1828, 1960 in Squaw Valley, California, United States. Squaw Valley was chosen to host the Games at the 1956 meeting of the International Olympic Committee (IOC). It was an undeveloped resort in 1955, so from 1956 to 1960 the infrastructure and all of the venues were built at a cost of US$80,000,000. It was designed to be intimate, allowing spectators and competitors to walk to nearly all the venues. Squaw Valley hosted athletes from thirty nations who competed in four sports and twenty-seven events. Women's speed skating and biathlon made their Olympic debuts. The organizers decided the bobsled events did not warrant the cost to build a venue, so for the first and only time bobsled was not on the Winter Olympic program. The Soviet Union dominated the medal count winning twenty-one medals, seven of which were gold. Soviet speed skaters Yevgeny Grishin and Lidiya Skoblikova won two gold medals each. Swedish cross-country skier Sixten Jernberg added a gold and silver to the four medals he won at the 1956 Winter Games.
