Ascent Trip Report

This ridgeline traverse trip included Johnson-Malcom-Koppen-DeRoux. Since I didn’t find any gps track or trip reports posted for this trip I thought I post it in case anyone else is planning to do this route.
The hike along Johnson creek was very pleasant with beautiful fall colors. Vegetation has taken over the trail in places, but the trail was easy to follow. There were lots of blown down trees blocking the trail. At one point I came across 2 ebikes and 1 motorbike stashed away. However, I never ran into the owners. The turn off to Johnson Mountain was very obvious and an obvious boot path was leading to the summit.
Continuing the trail to Malcolm Mountain included lots of ups and downs. None of the maps show a trail continuing right below and past Malcolm Mountain. Consequently, I missed the boot path leading to the summit by about 100 yards and had to backtrack a bit before gaining the ridgeline leading to summit. It was still early in the day and I had made good time. I looked at my GaiaGPS app and became motivated to continue on the Koppen Trail which follows the entire ridgeline. I also remembered seeing it on maps when I researched this possibility several weeks prior. My revised plan was to include Koppen and DeRoux, and then hitchhike back to my car.
Making a long story short, the Koppen Mountain trail is not very well established nor maintained. It is easy to lose the trail and find yourself on an animal trail. When getting closer to Koppen it is best to simply stay on the ridgeline, which includes some scrambling. After summitting Koppen Mountain I enjoyed finding myself on a decent trail again. When I reached the DeRoux Spur Trail I was determined to finish DeRoux (at this point it was the last peak on my Teanaway 20 list). I figured it was around 3 miles round trip from the point I was currently at and I could finish it in no time.
According the maps there is supposed to be somewhat of an established trail part of the way. Again, numerous times I ended up on animal trails. On my ascend I did a lot of side-hilling which was in a pain in the rear after what has already been a long day. After, summiting DeRoux upon my descent I stayed as close to the ridgeline as possible which turned out to be easier. It took longer than anticipated.
I reached the DeRoux Boulder Creek TH when it was getting dark. When I made the decision to include Koppen and DeRoux I was hopeful that I would be able to hitch hike back to my car. After I hit the main road a car stopped just to let me know that they were full. They felt bad for me. After hiking approximately 2.5 miles on the road a second car finally showed up with 3 people in it. Luckily, they gave me a ride back to my car which was roughly 1.5 miles.
