As the sun dips even farther below the western horizon,
it grows ever darker. (I remind myself that the sun really stays right where it
is; it's we who are rotating away from it.) I look upward, wondering how soon
I'll spot the first evening's star. The sky is a medium indigo color—not quite
yet ready to reveal that first pin point of starlight.
It hits me that I am watching a game of “photon
competition.” As the sun's profuse outpouring of photons (call it bright light)
gets intercepted by yonder ridge, it lowers the light level surrounding me. As
the sun’s photons decrease, the much fewer photons I receive from distant stars
will begin to get a chance to be noticed. Those stars scattered out their abundant
allotment of photons millions of years ago—a scant few of them finally reaching
my eye. They will become visible only when the arriving nighttime reduces the
sun's photons to near nonexistence.
The opposite of the rising ridge-shadow phenomenon visits
in the morning, as the sun's first rays illuminate the very tips of trees. The
shadows then retreat down the tree
trunks—slowly yielding to the new day's light.
I am reminded of a time a decade ago, when I meandered
through Glacier National Park in Montana, and then across the border into
Canada's Waterton Lakes National Park—the other half of that gorgeous
Waterton-Glacier International Peace Park. Camped on the Canadian side, I arose
before dawn to watch the morning's light slowly grow. I was greeted by the
stunning sight of a distant, tall Rocky Mountain peak bathed in a golden
spotlight, as the sun lit up the top of the mountain. I was riveted by the
view, watching the brilliant yellow creep down the mountain. Then I noticed a
dark, horizontal line etched across the mountain’s face. Curious! It didn't
seem as if it could be a rock formation, so what could it be? Then it seemed to
grow a wee bit larger and even appeared to undulate. Curioser!
Perplexed, I stared at this wavering black line, and then
noticed that it took on the appearance of a string of black pearls on a
quivering necklace. Finally, I watched as the black pearls transformed into
tiny Canada geese. Their wide V-formation grew larger, bore down upon me, and
eventually flew overhead. By then, the mountain was half bathed in light, and I
was still standing, unmoving, stunned.
When you take the time to register the sun's slow creep,
as shadows steal sluggishly across the landscape, like the minute hand of a
clock, another world exposes itself to you...a world that our rushed pace
usually keeps hidden from us. It's great to step away from that bustle and
become aware of a more measured world—one that lights up those serene places in
our consciousness.
