Named in 1881 for the ideal grazing lands and bands of wild horses that used to populate it, the Horse Heaven Hills are now home to dryland wheat farms.  Stretching from the cliffs at Wallula Gap to the east and slowly elevating to the west into the Cascade foothills, the Hills stir up a lot of weather due to their gentle northerly upward slope from the Columbia river. Also formed in part by the Ice Age floods, these hills are rich in nutrients for farming as well as hundreds of prehistoric fossils.
