HISTORY:   Some of the original horses in this area descended from Spanish Stock.  Today the herd is descended from US Army Cavalry remounts released prior to and during World War I, and historic draft and riding ranching stock.  Burros likely originated from historic sheep operations in the area.  Because Twin Peaks HMA has both horses and burros, it also is one of the few HMAs that has occasional mules.

ADOPTED ANIMALS:  See photos of animals adopted from the Twin Peaks HMA.
