Intro
Not an official breed, the Spanish Sulphur, Zebra Horse of Utah or Sulphur Springs Mustang are a particularly pure strain of feral Spanish Colonial Horse found in Utah.
Origins
Most horses in the Americas were imported by the Spanish during the 16th century, mustangs in particular tend to have heavy Spanish lineage. The herd found in Sulphur Springs tends to be quite unique as their genetics have remained incredibly pure, retaining characteristics of the Iberian blood of their ancestors. Notable because a large percentage of them possess primitive dun factor markings, including dorsal stripes and leg striping.
Due to their remote location in western Utah, the Sulphur Springs herd remained isolated enough not to have much outside influence. This is in part due to the harsh mountain environment of the area, maintaining robust genetics of the mustangs and discouraging other animals from contaminating the herd. DNA testing have concluded that the Sulphurs are related to primitive Iberian horses, particularly the Sorraia.
