West
Rattlesnake Mountain Via Hwy 18
04-05-25
It
was time for a long hike. I have
done this one the past two years. It makes for a good long workout
without seeing many other folks. I hiked up Mt. Si via the old trail on
Thursday and hoped I would be feeling well enough to make it all the
way up. I was out of the house at 6:40 am heading east. The day was
supposed to be partly to mostly cloudy but warming into the mid 60s at
the bottom. I arrived at the start just southeast of the Hwy 18 - I-90
junction at 7:16 am. It was 42F and a bit chilly. I was the only car
there. By 7:19 am I was on my way. The gate at the start is usually
closed but it was open this day. I headed down the paved road across
the swamp. Part way across I started seeing blooming skunk cabbage.
There was a lot of skunk cabbage. The sun was low in the sky but it lit
up the skunk cabbage. I saw more in a few places along my route but
most were right near the start. The road tuns and heads uphill. After
the short climb it is very flat until past the 2 mile mark. At half a
mile the paving ends. I reached the big power sub-station and had views
west to East Tiger Mountain. I was at about 1000' and would later be
above 3007' East Tiger.
My GPS added half my driving distance to my new track at the start even
though the app was not open on the drive. I canceled the track and
started a new one. Mission accomplished, I thought. At the 1 mile mark
I checked to see my speed. It said 45 mph and 18.3 miles finished. It
had again added half my driving miles at some point after I started the
new track. I just love technology at times. I did know when I started
and was able to mentally calculate miles per hour as the route has mile
and half mile markers. I made very good time on the flats with the cool
temperature helping. At about 2.1 miles the route began to climb. It
was still not very steep. I crossed Canyon Creek on the nice big bridge
and in a few minutes I was climbing higher. This section is straight up
the fall line. I felt good and kept pushing. At about 3 miles the route
turns right and the grade lessens significantly. I passed the spur road
I often use to push the distance up to 17 miles. That is taken on the
descent.
I passed the 3.5 mile sign and kept up a fast pace. I was very pleased
as less than two full days earlier we hiked 8 miles up Mt. Si gaining
3500'. We had slushy snow near the top which was harder to walk in. I
feared I would be sore and slow this day. That was not the case. At 4.5
miles there is a gated road turning left and heading uphill. That was
my route. I checked the time and it was 8:34 am. I had taken 1:15 to
hike 4.5 miles. That is 3.6 mph. That is fast for me. On my 2024, 2023,
and 2020 trips, I took exactly 1:19 each time. That is crazy
consistency over 4.5 miles. This trip was 4 minutes faster. I had a
fast food and water break and started uphill. Most of the elevation
gain is in the last 3.5 miles. About fifteen years ago this was a
forest walk to the summit. Now large parts of the route have been
clearcut. That is unfortunate for the forest but it does mean there are
some great views. The summit was just clearcut five or six years ago
and it has even better views.
The 5 mile marker is at a right switchback. The next switchback left is
right at the 6 mile marker. The views really began to open up now. So
far I had seen almost nobody, just as I expected. I did see two runners
coming towards me as I left the 4.5 mark but they did not follow me.
They were only seen at a distance. I still felt great as the elevation
gain continued. I saw blooming coltsfoot down low and most of the way
up. I looked for at least one blooming trillium but saw nothing going
up. I often do see them this time of year. The 6 mile marker is at the
bottom of a dip. Climbing out of it is about the biggest uphill on the
way back. At about 6.5 miles the road meets a road that comes up from
the Snoqualmie Point Road just off I-90. That seems to be the new main
road to the summit for service vehicles. The rest of the mileage
markers are for that route. I turned right and continued to ascend.
Before and after the junction I was in forest. Higher up it would be
mostly in clearcuts.
The overcast was supposed to come in by late morning but so far I still
had mostly blue sky. To the south it was all blue and to the northeast
it was turning white. As I rose, the tops of the Olympic Mountains
began to come into view to the right and left of East Tiger. Soon Tiger
1 was in view. Higher still, they Olympic peaks were coming into view
over Tiger peaks. I passed the bicycle trail that comes up from
Snoqualmie Point. I saw a biker zoom down and across the road as I came
nearer. I would see lots of bikers until I reached this spot coming
down. I was after miles so I stayed on the road. The summit towers of
West Rattlesnake Mountain were now is sight above the big clearcut. The
road entered forest and reached the last switchback right. The
Rattlesnake Mountain hiking trail is only about 50' away and I often
cut across on trips up the RMT that loop over West Rattlesnake. This
day I stayed on the road. It came back out of the forest with some very
nice views. I took more photos but kept up my pace.
I noticed a little snow in the ditch along the road. There was more
snow here in the past couple weeks. I crossed two bike trails and had
one ore switchback left before the towers were right in front of me. It
just took a few more minutes to reach the summit. I arrived at 9:54 am.
I had hiked 8 miles with about 2350 of gain in 2:35. That is 3.1 mph.
That is a great time for me. Last year I took 2:50. The road is very
smooth and never overly steep. Perfect for a fast hike. Now I had views
in all directions. I looked north and Mt. Baker and Three Fingers
Mountain were very clear. Blue sky would have been better but I was
still pleased with the views. To the south I could see part of Mt.
Rainier and it really stood out. I had to walk a short way off the road
into a clearcut to find a stump that put above the small new trees for
a clear shot of Mt. Rainier. I took a food and water break and then
walked to the east side of the summit for views of Mt. Si, Mt.
Teneriffe, and peaks along I-90. Granite Mountain was all snow on top
and Mailbox Peak across the valley had snow near the top. The views
were very good. I dropped to the lower towers and returned. Several
groups of mountain bikers passed by during my summit stay.
There was a light cold breeze but a wind shirt fixed that. I would
liked to have spent a few hours on top but I had a long trip back and
the college basketball final four was on in late afternoon. After 50
minutes I packed up and headed down. I left at 10:44 am. It was still
pretty early in the day. I was not in a hurry hiking down. I still made
good time but did not push it at all. 17 miles nearly double my average
hike and I did not want to end up too sore. Coming down I had a view to
the northeast that was blocked on the summit. I saw a snowy Mt. Index
and Glacier Peak. I enjoyed the views as the Olympic Mountains began to
slide behind Tiger Mountain. At about the 5 mile mark I started looking
very closely for at least one trillium. I saw no leaves at all until a
look through the trees along the road showed a blob of white. I crossed
the ditch and poked by way though a little brush into the forest. And
there was a perfect trillium. Then I saw another and another and
another. That supplied my trillium fix for the weekend.
Back at the 4.5 mile marker I took another short break. It was now
noticeably warmer. The wind shirt came off. Other than the one steep
down the fall line section it was a very gentle grade going back from
here. I did take the short route to another bridge over Canyon Creek
that rounded my trip up to 17 miles. I retraced my steps to the main
route and dropped the steeper section. As I approached the main bridge
over Canyon Creek I met a big group of a dozen or so mountain bikers.
They never did pass me going out. My legs were getting a bit sore after
15 miles but I kept up a reasonably fast pace the last two miles. I
reached my car at 1:57 pm. There were now six other cars next to mine.
This proved to be a very nice hike. I had my fastest time up just two
days after a strenuous hike up Mt. Si. I felt pretty good on the entire
trip. The cool start and great views really made this a good hike. At
the conclusion my car registered 67F. It was plenty warm coming down. I
expected to see bikers near the top and I did. I did not expect the big
group near the end but I only saw them once. Otherwise, it was a
lonesome hike pretty close to home. I ended up with several hundred
photos as there was a whole lot to see and enjoy. My drive home was
more interesting. Highway 18 has been under construction adding two new
lanes for a couple years. Now the interchange with I-90 is a work in
progress. My return required me to take I-90 east then head back went.
West bound I-90 had the Hwy 18 exit closed sending those drivers west
to Preston to turn around and detour back. That led to a backup west
bound from 18 to Preston. The bumper to bumper traffic was a small
price to pay for a great day doing a long hike to great views.
