Elk shoulder height (in inches) = (Length of hoof print in inches x 2) + 10
For example, if the hoof print is 4 inches long and 3 inches wide, the elk's shoulder height would be approximately (4 x 2) + 10 = 18 inches.
It's important to note that this formula is just an estimate and may not be exact for every elk. However, it can give you a general idea of the elk's size.
