The Appaloosa horse breed originated in the Palouse region of southeastern Washington and northern Idaho with the Nez Perce Indian tribe around 1877.
Many people still live on farms and own horses in the Palouse. When my husband and I were raising our kids, our girls were big into horses. We owned four--three quarter horses and an Arabian--but never an Appaloosa.
The Appaloosa Horse Museum is located in Moscow, Idaho.
