Mounds near Black Hawk Tower, at Milan, are scattered along for the 

 distance of a mile. They are about 3 feet high, from 30 to GO feet in 

 diameter, and, for the most part, are undisturbed. They are all burial 

 mounds, and follow no particular arrangement, lying in rows on a bluff 

 130 feet above Eock River. Black Hawk Tower is an elevated spot near 

 the falls of Bock River, on the southeast corner of Bock Island Bluffs. 

 The view from this point extends 8 or 10 miles up Bock Eiver, and G or 

 8 miles northward to the Mississippi. Black Hawk is said to have used 

 this site in the war as a lookout for his enemies.
