Who knew! Highlands Ranch, Colorado was part of the Louisiana Purchase.
Because Highlands Ranch, Colorado was part of the Mississippi River Drainage Area, it was claimed for France by French explorer René-Robert Cavelier, Sieur de La Salle.It was named as part of "Louisiana" in 1682! The Spanish gained Louisiana in 1763, and returned it to France in 1801.
This area of what is now Northern Douglas County, was in the Louisiana Purchase when it was sold to the United States in 1803.
I doubt the window and gutter cleaning business was any good in 1803.
