After visiting Crystal Lake Cave we drove over to Mines of Spain Recreation Area. This park, which features woodlands and rugged limestone bluffs, is the location of Julian Dubuque's monument. That man was born in 1762 in Canada. When he came to this area of Iowa he was active in trading and mining with the Fox and Sauk Indians. In 1788 Dubuque obtained an official land grant from Spanish Governor Baron de Carondelet in St.Louis which gave him 73,324 acres of land. This land, shown in early 18th century maps as "Lead Mines", became known as "Mines of Spain". His monument is marked by a tall brick tower overlooking the Mississippi River. From that site I took the picture posted below. On the left side of the picture below can be seen the town of Dubuque, which Julien Dubuque founded.
