Better a track confirmed that it was a Bigfoot and that nicely eliminates the alternative of the Giant sloth.. Other evidence conforms completely to a Bigfoot interpretation.
In addition a second sighting took place three days earlier and twenty mile away. Presuming that they bush whacked between the two points we see ten mile of travel as normal. Presuming ranges are generally involved, this helps us to estimate size of local ranges which are likely extensive. Yet a range of fifteen miles around a permanent den appears plausible.
The creature must carry back a deer to its den and that suggests no more than a days travel at speed.
