What's up with the "dale" in "Southdale", "Ridgedale", "Rosedale" and "Brookdale"?

Question

In the Twin Cities (http://en.wikipedia.org/wiki/Minneapolis-St._Paul), there are 4 shopping malls that all end in "dale". Some people in Minnesota might say things like "there are no Nordstrom's in any of the "dales" but there is one at the Mall of America". What's up with the "dale" suffix? Are there other malls in the country that use "dale" and a prefix suggesting where they are located? (such as Southdale which is located in the south side of the twin cities).

Answer 1

Over hill, over dale, we will hit the dusty trail
And go shopping until they close!

Answer 2

I've wondered the same thing many times. I don't get why some are "dales" and some aren't. Like Burnsville center and Eden Prairie Mall...Sad to say, but I believe the world may never know.

Answer 3

I always guessed that the cities thought it would help people remember that there are different malls around the area so if you can't find what you want at one, another isn't too far away.
