What does the third totem pole mean?

Hint 1 of 9:

Ask the bigfoots about the totem poles.  Each bigfoot will have an opinion
about their meaning.  Even Max may have an idea.

Hint 2 of 9:

The image emblazoned here is that of a mysterious old face in a cornucopia
of vegetables.

Hint 3 of 9:

Look closely at the face.  Haven't you seen him somewhere before?  (No, it's
not the relative whose name you can never remember at family gatherings.)

Hint 4 of 9:

Perhaps as the focus of a strange bit of post-mortem animal edu-tainment?

Hint 5 of 9:

That's right, it's famed naturalist John Muir, whose picture is on display
in a small corner of Bumpusville.

Hint 6 of 9:

Think of a connection between the picture and vegetables.
