Some of the first archaeological expeditions to Iran began in the mid 19th century, when British and French archaeologists investigated the site of Susa in southwestern Iran. Over the following decades, excavations were predominantly conducted by American, British, French, German, and Iranian sponsored expeditions throughout Iran. Many of these early excavations proved successful in uncovering a wealth of artifacts, architecture, and information pertaining to the ancient civilizations of the region.
“Never have I beheld any spectacle which…so forcibly taught the lesson of humility to man as a total eclipse of the Sun.”

John Baptiste DuBay is believed to have been born July 10, 1810 in Green Bay, Wisconsin. His father was John Louis DuBay, a French-Canadian fur trader from Montreal, rumored to be the first European in Portage County. His mother is thought to be a Menominee woman, possibly the daughter of Chief Pewatenot (Menominee). Little else is known about DuBay until his involvement in the fur trade in his early teens.

The Spencer Lake site was excavated in 1936 by W. C. McKern, Milwaukee Public Museum Curator of Anthropology at that time. The site is an ancient (AD 1100–1400) burial mound located near Spencer Lake in Burnett County in northwest Wisconsin. At the bottom of the mound, an intact horse skull was discovered, a startling find as it was believed that horses had gone extinct in North America around 10-12 thousand years ago and not reintroduced until the arrival of the Spanish. Two students, upon hearing of the discovery, confessed to placing the skull at the bottom of a pit they had dug into the mound, but McKern and his crew were positive that there was no disturbance of the soils around it.
In 2004, a sample was taken from the skull and sent to two different labs for radiocarbon dating. Both lab results confirmed that the Spencer Lake horse skull was modern, and that the horse had most likely lived during the late eighteenth century or early nineteenth century. (110+/-40 BP; Beta-167209, and 190+/-35 BP; Stafford SR-6189).
