Before the lush green and floods of spring give way to the brown
and dry conditions of summer.
I was walking in Island Park in Salmon, Idaho, the other evening
when I heard a long, sharp cracking sound. From the trail I
looked to my right just in time to see a medium-sized cottonwood
tree -- twenty or thirty feet tall -- crash with a splash into
the Salmon River from the opposite bank. The river had undermined
the tree's roots, and it splintered and toppled over of its own
weight. I watched the surging current sweep it away as the
branches whipped and thrashed under the low bridge that leads
into the park, and then drift easily under the higher Route 93
highway bridge.
The Salmon River -- like all rivers in the Rockies -- is now in
its annual mid-May to mid-June flood as the snow comes out of the
mountains. Here the snow doesn't just melt, it moves; filling
hundreds of creek drainages that in turn feed the rivers. This
year it started slowly, but got a big jolt by a regionwide
mini-heat wave in the 90s on the weekend of May 16-17. It's
cooled off since then, but the river stays high, and will remain
so for a couple more weeks. The mountain snowpack as viewed from
Salmon looks more mottled everyday.
The river is the color of coffee with cream. Gravel bars with
willow brush growing on them have disappeared, leaving the top
couple of feet of willows waving and pointing downriver in the
onslaught. Logs, limbs, and odd debris bob downstream. On that
first hot weekend when the river was rising but still clear (and
bracing cold), I watched some high school kids jumping off the
low bridge. The current swept them along for fifty yards, and as
it did they swam to their right and across it, neatly washing up
on the concrete boat ramp under the highway bridge, then wading
out and repeating the amusing ritual. But the hot weather
supercharged the river in the following days, and the swimmers
have temporarily disappeared, as has the boat ramp, when the
river rose another two feet up the highway bridge abutments.
I've reached my first anniversary of living in Salmon (I moved
here during the first week of June, 2008), and while I recall
that the river was high upon my arrival last year, it seems much
higher this year. This year, low grassy areas of Island Park are
underwater, not because the river has overwhelmed park, but
because the water table has risen so much that it's invading the
park from below. The river is literally under the park. So much
for softball or Frisbee-tossing or playing fetch with Fido --
unless you're wearing rubber boots. And north of town there's a
ranch near the river with a corral that's usually home to four
horses, but not lately. I rode by on my bike the other day to
discover that they had been relocated somewhere, and the corral
was momentarily home to a mated pair of mallards swimming around
as if it were a fenced-in pond.
I see by my regional online newspapers that this flooding is
uniform across the Northern Rockies. As I write, flood watches
and warnings have been posted for many of the rivers of Idaho,
Wyoming, and Montana, with the Yellowstone in the latter state
especially ornery. Livingston, Montana, seems to be annually
under the gun, as it is this year.
But all the melting snow and some recent rainy days do make this
part of the world a lovely place to live at this time of the
year. Brown and roily rivers and creeks are contrasted with a
rich green. Viewed from my kitchen window the sagebrush slopes of
the Salmon River Mountains running up to the pines remind me of a
trip I once took to Ireland. On those verdant slopes are tiny
black specks that look like pepper spilled on a pool table. My
binoculars show me that they are Black Angus steers grazing. The
cottonwoods and gnarly white aspens along the river have fresh
new fluttering leaves, and Salmon's ubiquitous in-every-yard
lilac bushes are all in purplish fragrant bloom. The whining of
distant lawnmowers is heard. Backyards have the loamy rectangles
of freshly rototilled garden plots.
All this verdure will last until approximately the Fourth of
July, when the landscape will slowly return to its normally arid,
brown state. Wallace Stegner once said that to live successfully
in the West, one must get over the idea of green. So water that
lawn and garden to keep them alive. Ranchers will be irrigating
pastures, those horses will be back in a dusty corral, and those
kids will be jumping off the bridge again in the blazing
afternoons of summer. Kayakers and rafting enthusiasts will be
bobbing under the bridges and waving at the kids. The gravel bars
will reappear, and the mountains will be their summertime
gray-granite selves with a gash of snow holding on here and
there. And that cottonwood tree will eventually wash up on a
gravel bar.
Way, way down on the Salmon River.
