The northeast Iowa area around Pikes Peak State Park is one of the most beautiful and interesting regions of Iowa.  The region is rich in history, with the precipitous rock bluffs recording a geologic history beginning nearly 530 million years ago and continuing today as erosion along the Mississippi River and its tributaries continue to expose more of the rock record.  Many plant and animal communities have inhabited the region, changing and evolving with climatic and cultural changes.  The long history of Native American residents is symbolized by the large number of mounds on ridge tops and in the valleys on high terraces, many shaped as animal effigies.  The arrival of Father Marquette and Louis Joliet in the region in 1673 opened a new phase of rich and interesting history.  Hunters, trappers, and miners were the earliest historic residents.  The region became a part of the United States with the purchase of the Louisiana territory in 1803, and was explored by Zebulon Pike shortly thereafter.  Military forts were constructed, towns established, and roads constructed.  The length of this guidebook is a testimony to the natural bounty and colorful history of this region, with articles discussing the National Fish & Wildlife Refuge, Effigy Mounds National Monument, the Corps of Engineers construction of the Mississippi River lock and dam system, and Wisconsin’s Wyalusing State Park across the river, as well as discussions of such special are residents as Andrew Clemens and the Ringling Brothers.  Since the beauty of the area is difficult to display in black and white photography, we have also included two pages with color plates in this guidebook for the first time.  The authors and I hope that you find the material in this guidebook and the field trip experience to be informative and interesting.  And, be careful, there are many dangers to be encountered on the way to many of the field trip stops, but enjoy yourselves.
