Equus caballus
A single rounded hoof — the easiest large track on any trail.
4–6 in across. One solid rounded hoof, not cloven. U-shaped shoe rim if shod. V-shaped frog mark in the center. Regular walking line on trails and roads.
Pasture, trails, rangeland, desert (wild bands). Worldwide; wild bands across the western U.S..
Diurnal
Grasses and forage
Wild horse hooves self-trim on rocky ground — no farrier required.
Should I be concerned?
Never approach wild horses; stay 50 feet back and don't get behind one.
