Just seeing this thread now!
I had heard of the PNW Trail but it wasn't really on my radar until a trip to Montana last fall when some trails I rode turned out to be segments of the PNW Trail.
First up was the Webb Trail on the west side of Lake Koocanusa. I wasn't aware the PWN Trail extended into Montana so I was a little surprised to see this sign at the bottom
This got me interested to explore a bit more up top as well. I headed west and found a bit of cool trail but it soon joined an overgrown forest road that kinda sucked. From what I've read there is a lot of this on the PNW Trail.
Headed back toward the Webb Fire Lookout tower where the descent begins. Tons of fresh bear sign up there. Not scat, but entire sections of trail dug up looking for grubs. The descent was rocky and fun, 3,300ft in 5 miles.
The main target for rides in this area was the Ten Lakes Scenic Area. Look what I found once again....
Here it is the Highline Trail that is part of the PNW Trail.
I did three days of riding with each days ride using portions of PNW Trail
Looking down on Therriault Lake
Larches were in prime color
Views from the Highline Trail did not disappoint. It stays pretty high around much of the Ten Lakes Basin
High quality alpine singletrack
I rode this section both directions. Some HAB going uphill but the ride down Wolverine Basin was worth it.
There was a price to pay to ride this as a descent too, which I did by climbing up to the ridge on Poorman Mtn
Some really steep sidehill riding in places. For the most part the trails were in great shape.
Another segment - the Whitefish Divide Trail. Called Ralph Thayer Memorial Trail on Trailforks. Didn't realize this was part of PNW Trail until the end of the ride when I saw this sign
We rode from south at the fire lookout heading north. Great views up top
The trail follows the west side of the ridge for a while.
Then you spend a bunch of time in forest with a number of steep climbs and descents.
We dropped down Swede Creek in the middle rather than continue on. I planned to go back and ride the remaining section the next day but was foiled by rain. Whitefish Divide continues north of what is shown on TF but runs through burn areas and is pretty much non-existent from what I'm told.
All of these trails are in heavy grizz country so make sure you have bear spray if you go. Lots of recent bear sign was seen on all rides.
Glad I was able to explore some bits and pieces of this trail!
