The Ancient Oak tree has been overlooking the Mississippi River Gorge for a long time.  From its site on the bluff it witnessed the growth of the Minneapolis skyline.  This quietly dignified tree is located about 2 miles downstream from what is now called Saint Anthony Falls.  This great tree may have over heard the Dakota refering to the only falls on the Mississppi as "O-Wa-Mni" (whirlpool) or “Ha-Ha Tanka” (waterfall).  
This tree has been observing this area since before Minneapolis was incorporated as a city, before Fort Snelling was built downstream in 1819 by the United States Army, before the United States Government pressed the Mdewakanton band of the Dakota to sell the land on which it's roots hold, and possibly before French explorers arrived around 1680.  If we could only hear the stories this tree could tell from all it has witnessed.
It would be an understatement to say the tree has been through a lot in its long lifetime.  This spring 2010 this urban forest treasure did not leaf out.  Below is information from the Minneapolis Park & Recreation Board Forestry Division about the Ancient Oak.
