Ramsey Falls, Redwood Falls,MN. This 45-ft tall waterfall in the Alexander Ramsey park in Redwood Falls cascades down a picturesque granite ravine in a heavily wooded bluff area. Ramsey Park is the largest municipal park in the state and is located in the Minnesota River Valley in southwestern MN.
Thoroughbred heights can range anywhere from 15 hh (hands high) to 17.3 hh for the freakishly taller ones.
Clydesdales can also grow that big, in fact Big Jake stole the world record for tallest horse from a Clydesdale by just two and three-quarters inches. According to my handy encylopedia though, Clydesdales are usually around 16.3, so I guess the biggest natural breed would be the Shire of England.
