Lemhi Pass
The story of Lewis and Clark and
their Indian guide Sacajawea is one of America's
favorite old west exploration stories. And since
this was an official expedition, record keeping
was excellent - as opposed to some of the private
trapper explorations of John Colter, who may have
been chased down the Yellowstone naked by Indians,
but nobody knows exactly where. But we know what
Captain Lewis wrote and said, where they camped,
and other stories, such as giving birth along the
way. Lemhi Pass is where Lewis and Clarke ended up
crossing the continental divide, and the result is
an official US landmark pass, which makes a great
bike ride.

Approaches
From East. The approach form this side is
much lower than the western side and the road is
in better condition. The turnoff to Lemhi Pass
road is located at a series of low hills named
Shoshone Ridge, and is well signed. On Shoshone
Ridge a few tablets outline the history of the
pass. The pass road starts out in high flat
sagebrush and grazing country, a wide, hard
medalled path, bordered on the sides by private
land as indicated by wood barrier fences, rather
than the more ordinary picket wire fences. After a
short distance the road enters the hills and meets
Horse Prarie Creek. This would have been a great
space to camp, but apparently they went a few
miles further upstream on that day in August. The
road continues to climb gently through widely
spaced farms. The grade increases where the road
enters the national landmark. It's the first time
that the climb becomes really noticeable on a
bicycle. But it levels out again after the single
switchback to the summit. To the south there is a
1/4 mile spur to a peaceful group of picnic
tables, named the Sacajawea memorial area. Two
tablets state that there are many interesting
stories concerning Sacajawea, and then goes on the
tell the story of the woman whose wish it was to
establish the memorial, not mentioning
"Sacajawea's interesting stories" again.
From West. (described
downwards). There are actually two approaches. The
longer one leads over a higher elevation to meet
Id28 further north. The approach described here
descends directly to Id28 at Tendoy. Looking down
the steep grade, canyons and peaks behind lower,
green ridges, this looks like a formidable pass,
and one can empathize with Lewis's original words,
that are now used to start the National Landmark
pamphlet: "we proceeded on the dividing ridged
from which I discovered ranges of high mountains
still to the west of us...". But on this ride we
don't have to cross them and the way down is
pretty fast. The road over here is rougher, much
steeper and the top is very washboard like. As the
grade levels out conditions improve. Two more
signs pinpoint a Lewis campsite and also a stage
coach stop. Tendoy has one store with potato
chips, tiny little cans of wieners, soda and
things like that.

History
Lewis and Clarke: (<Pipestone Pass|Lost
Trail Pass>) In 1803 something so stunningly
unexpected happened, that it would sound too
contrived for a novel, if it had not actually
happened. Napoleon sold, what was at that time
called Louisiana, to president Jefferson for 15
million dollars, effectively doubling the size of
the United States on paper. Already before the
Louisiana Purchase Jefferson had shown interest in
exploring for the mouth of the Columbia, and had
laid plans for such an expedition. He assumed that
there was a close connection between the Columbia
and Missouri river systems. Captain Lewis also
guessed that the Missourri started at a low pass
in the northern Rockies, using data from
MacKenzie's Pacific journal and Indian hearsay.
Without this assumption this story would have
developed completely differently. The planned
route was up the "just yesterday French owned"
Missouri to the English coveted North West. They
left from (town of) Missouri May 1804 and took one
full year to travel the known extend of the
Louisiana Purchase to today's area of Bismark,
North Dakota.
Rumors in the spring of 1805 that British
trappers of the North West company were also
heading for the Pacific lead new urgency to their
plans that spring. Lewis and Clarke continued by
boat up the Missouri and saw the mountains first
at the mouth of Marias River, named for Clarke's
love interest. The mountains were still 100 miles
away. This actually would have been a good route
to the Columbia, as the Great Northern Railroad
showed a century later by laying rails over Marias
Pass, but Lewis and Clarke decided to follow the
Missouri further upstream. This lead them south.
However one thing became clear at the sight of
these great mountains. This was not just a boat
journey with a short portage. The first portage
around Great Falls, Montana drove the point home.
They needed horses to pack eight boat loads of
stuff. And so all the preparation, study of
astronomy and navigation took a back seat to an
unexpected turn in the story. Along in Lewis and
Clarke's party was not only John Colter - who
would become the legendary explorer and teller of
tall tales returning from Yellowstone Park, naked
chased by Indians - not only Toussannt
Charbonneau, aging French Canadian interpreter
with the Indians, but also his de facto teenage
wife - boat woman. Today signs along western
highways refer to her as Sacajawea. She was a
Snake Indian who had been captured by Minitaree
Indians, eventually selling her to the French
Canadian Interpreter. The and most important fact
about her in this story is that her tribe owned
horses, desired by Lewis and Clarke for the
upcoming portage.. And so one of the most popular
stories of exploration of the American west
begins.
July 22nd was a happy day. The expediton camped
near Three Forks, and Sacajawea announced she knew
exactly where they were. She recognized the place
where she had been captured by Minitarrees in
1799. On August 8th the news was even better. The
Indian girl saw a landmark closer to her home,
Beaverhead Rock - another Lewis and Clarke trail
waymarker today. Looking west the horizon was and
is dominated by the Pioneer Mountains. But kindly
enough, they do not reach very far south, and
beyond them are several gaps in the ever so gently
rising horizon. One of them is Lemhi Pass. Lewis
scouted ahead with three men. It took three days
to reach this gentle gap and during that time they
observed an Indian fleeing on a horse - a
promising sign. Lewis succeeded in making friend
with the Snake Chief Cameahwait, who also was boat
woman's brother. After two weeks of deal making
and social business, Lewis crossed back over Lemhi
Pass with horses and accompanying Snake warriors.
The Lewis and Clarke party united and again
crossed Lemhi Pass a third time, to the Snake
River, after having cached all the boats near the
mouth of Horse Prarie Creek. The journal notes
that a lagging Indian helper gave birth during the
descend on the western side of the pass.
Even though the Salmon flows generally in the
right direction, north and west, further
examination of the topography and the Salmon
rapids convinced them that the best way forward
was north and back over the Bitterroot Mountains
again, in the direction of Marias River. The next
pass they crossed and is also named is Lost Trail
Pass.
Montana Gold Rush (<Bannack
Pass|Badger Pass>) Lemhi Pass along with
Bannack Pass were used by gold seekers who
approached the town of Bannack from the west.
