The rock outcrop in the right background of this photo is identified by the local populace as Legendary Rock.
There is no description on the back of the card.
Legendary Rock is not identifiable today, so it may no longer be known by that name. Maiden Rock is located somewhat north of Pepin, Wisconsin along Lake Pepin, which is part of the Mississippi River and forms part of the boundary between Wisconsin and Minnesota.
This card likely dates from the 1930s.
