Maybe, but what if a week before, let's say, someone else had hiked there? I don't know how long prints last in that soil, wind, etc. (Presumably no rain recently.)
LE said they followed footprints "consistent with the family size" so whichever way they went was known, it's just not been made clear to us.
And I wondered whether LE would have sent searchers down both routes at once -- in hindsight of course we know they would have been found sooner by the searchers going down S-L because they would have only gone 1.5 miles before finding them.
MOO
Prints would be fresh and similar on both sides....so I think they could be differentiated from older prints DOG prints would be very specific......just my take.
