You can measure this print made by a healthy footed mustang and it will meet the 1/3 2/3 balance.

This hoof is from a mustang brought into captivity 5 weeks earlier.  Notice that the natural heel height of this 1100 lb horse is the average 1 1/8 inch

This mustang hoof was from the Nevada desert.  What was extremely informational is the creases from the middle of the back half of the central sulcus

angles out just as Martha Olivo drew in her diagrams of  when mapping the hoof.  The creases angle to the fulcrum and is called the sulcus radius.

Look in the mapping section and you will also see that the sulcus radius consistently will cross over at the end of the bar where there can be seen a

fracture.

This is another dried up mustang hoof that shows the beautiful concavity and also the nice smooth mustang roll.

Depending on the time of year the "mustang roll" which is more of a bevel will have a different edge.  What

is interesting with this capsule is the surplus of capsule tubules that are sort of drape down the capsule.

Look closely to the lower 1/3 of the capsule and you can see the separated unpolished wall.
