Bozeman Airport Medalions - Sacajawea Started Today

I was asked by Jim Dolan, a Bozman Montana Artist, who creates welded sculptures (http://www.jimdolanart.com/), to help with a project he's doing for the Bozeman Airport. I'm doing 6 medallions of Lewis and Clark, Sacajawea, Thomas Jefferson, James Madison, and Albert Gallatine. Merriwether Lewis, and William clark, along with Sacajawea, made up the "Corps of Discovery Expedition" (1804--1806). It was the first transcontinental expedition to the Pacific Coast by the United States. Commissioned by President Thomas Jefferson. Their objects were both scientific and commercial -- to study the area's plants, animal life, and geography, and to discover how the region could be exploited economically. Part of that expedition was to find the headwaters of the Missouri River. Three rivers formed the headwaters of the Missouri River and they were named after President Jefferson, Madison, and Gallatin in July of 1805. Those headwaters are just 45 miles north of where I live. It's kinda cool.
