These mounds of earth mark the site of an archaeological "dig" west of Dubuque in 2013. Federal law in 2013 required an archaeological survey of any lands being excavated for construction. This included the area for the Bee Branch flood prevention project and land just west of Dubuque for new highway construction. "Digs," excavations of sites looking for artifacts in 2012 and 2013 west of Dubuque found remains of hunting camps dating back 7,000 years.
ARCHAEOLOGICAL HISTORY. The archaeological history of Dubuque County began in the late 19th and early 20th centuries when many burial mounds and mound groups were located, mapped, and excavated. In 1968, an attempt was made to discover the remains of the house used by Julien DUBUQUE. This excavation, by the Office of the State Archaeologist, did find a miner's cabin of the 1830s and a Late Woodland burial.

In 1973, a survey was carried out south of Dubuque to locate and identify both prehistoric and historic habitation in the MINES OF SPAIN area. This work centered on the mouth of CATFISH CREEK but included the bluffs along the MISSISSIPPI RIVER. The project successfully located and recorded several examples of prehistoric and historic sites.

In 1977, Anton Till conducted an archaeological survey. Focusing on the bluffs along the Mississippi, the project recorded four sites within the Mines of Spain. An attempt to not only locate the previously recorded sites but find new locations took place during the summer of 1981. As a result of the effort, ten of the fifteen previously recorded sites were relocated and an additional fifty-eight new prehistoric sites and seventy-nine new historic sites were discovered and recorded.

The same survey crew in 1977 discovered between Dubuque and Sageville west of Highway 52 North, what became known as the LITTLE MAQUOKETA RIVER MOUNDS PRESERVE described as eastern Iowa's best preserved prehistoric burial sites. The 42-acre parcel was purchased by the Iowa Department of Transportation in 1977 with assistance from federal, state and local agencies in cooperation with Native American representatives. Constructed between 200 A.D. and 1700 A.D. the mounds ranged from one to four feet. An estimated ten thousand loads of earth were carried to the site by people using stone implements and baskets.

In 1994, excavations on KELLY'S BLUFF in Dubuque resulted in the discovery of human bones. These were believed to be the remains of bodies buried on the site when the hill was used as the THIRD STREET CEMETERY, a Catholic cemetery. Similar findings were made in 2005-2006 when construction work began on a proposed building on the premises.

In 1995, prior to reconstruction work on Highway 52 exploration of archaeologically-sensitive sites was carried out between Dubuque and Bellevue. This led to the discovery of what was later known as the Carroll Rock Shelter. The excavation of 1,097 artifacts resulted in the site being dated to 600-900 A.D. (2)

In 2012 a site was explored west of Dubuque along Highway 20. The site, one of six planned construction sites considered eligible for listing in the National Register of Historic Places, was destined to be an interchange for the Southwest Arterial. Among the artifacts recovered were tools, tool fragments, small rock formations and possible campfire locations. A small leather punch tool discovered dated from 2,500 to 7,000 B.C. (3)
