The Mountain Pottok is a subtype of the Pottok. It is one of the most ancient equine breeds still in existence.

The mountain pony of the French Pyrenees:
Pottok ponies have lived on the French side of the Pyrenees Mountains ever since their ancestors arrived in the Basque region during the last Ice Age.

Over the course of thousands of years, these ponies developed strong hooves, excellent endurance, an extra-long upper lip, and thick whiskers that protect their lips during winter time, all of which are adaptations that help them locate and survive on the rough vegetation that the Pyrenees have to offer.

The ancestors of the Prairie Pottok:
For many years, these ponies were used as pack and pit ponies. Still, they were allowed to roam freely in the mountains and breed in purity. Pure descendants of these ponies still roam the mountains today and are called "Mountain Pottoks".

During the second half of the 20th century, some of the Mountain Pottoks were bred to serve as riding ponies. They were selected for their size and athletic performance, and were kept in meadows where foals began their training from the day they were born. These Pottok ponies grew into a completely different subtype of the Pottok pony, known today as "Prairie Pottok".

The Mountain Pottok today:
Today, Mountain Pottoks roam the mountains as semi-feral for at least 9 months each year. Still, they all have owners who round them up twice or thrice a year to receive medical treatments if necessary. Other than that, the ponies are on their own, grazing on whatever the mountains have to offer.

Mountain Pottoks are bred in a pure manner, meaning that crossbreeding them is not allowed, not even with Prarie Pottoks (see 'Prairie Pottok.)

Conformation:
Unlike their athletic cousins, Mountain Pottoks still have the compact conformation of the original Pottok, in the sense that their back and legs are shorter, their size is smaller, and their height is shorter.
