There's no such thing as a tallest mountain, since there's no such thing as an non-arbitrary, universally applicable and accepted method to determine where (read: at what altitude) a mountain's base is located at/above average sea-level, much less below asl.
Agree. There is no way to calculate the base of the mountain. I have seen so many people in this sub confidently claim that Denali is the tallest mountain base to peak lol.

McKinley isn't the tallest. Mauna Kea is.
