- Mother: I want my 4-year-old son to climb a mountain;
not so easy in Wisconsin.
[spinning sunglasses make 'skeedaddle' sound]
Long ago, mountains as high as the Rockies
covered the area which is now our state.
But today,
I'll have to settle for 1,942-foot Rib Mountain.
It's a remnant of that ancient Rocky-sized range,
buried by sediment, then revealed through erosion.
I'm not concerned by the modest elevation
because this mountain
sports something more impressive:
its age.
Rib Mountain contains some of the oldest rock in the world.
At 1.7 billion years old,
these rocks have been around
for more than a third of the Earth's existence.
We rub our hands
across the striations on the side of a boulder,
made by waves
when the now quartzite
was a river valley or ocean bottom.
"Long ago, this rock used to be sand," I say.
I am awed by this evidence of the rock's previous forms.
First sand, then sandstone, now quartzite.
I tell my son to think about the ripples
the ocean makes along the seashore.
He gets it.
Looking around the heavily wooded mountaintop
and responding,
"There must not have been any trees here then."
Next, I tell him the rock's age,
knowing full well his understanding of such things
still has a long way to go.
His own number of fingers and toes
as yet a daily discovery.
This window of not-yet-complete awareness
of his own form might be a good time, I figure,
to convince him of what we, like the rock, really are--
"The rock is old,"
I say to my son.
"But you and the rock are really the same age,
around 13.8 billion years old.
The atoms in your body and the atoms in the rock
made just after the birth of the universe
and in exploding stars.
You are stardust."
'Stardust,' he repeats, and smiles.
He's heard me say it before.
I want my son to take the long view,
to think like a mountain,
even when he is not on the mountain,
and not only about the Earth, as Aldo Leopold imparted,
but about himself.
We should not get mired
in how one strand of identity formulates us.
But consider all the strands:
the food we eat,
the microbes we host,
where we grow up,
and the DNA we inherit.
No more or less important
than the atoms that make up all this stuff.
I don't deny what we appreciate in the rock,
its consistency of form, being itself,
over such an unimaginable period of time.
It's old;
it's something;
it has exactly the sort of permanence we ourselves desire.
I come to the mountain today
not only in a parent's feeble attempt
to make my son seem immortal
but to help him better navigate life's journey;
it's hard facts, as well as its uncertainties.
One hundred years;
the most humans can expect
is not much.
Yet over that 100 years,
our solid seeming body is in constant change;
individual cells live from a few days to at most 10 years,
continuously rebuilt from materials
from our immediate environment.
We are not sandstone then quartzite for a billion years
or even human for one hundred.
We are sea, land, and sky
all in one lifetime. [object whooshing through the cosmos]]
