I'm glad I had a plan "B" in mind!
I set off today with the intention to scout the length of the Silver-Skagit/Ross Lake Forest Service road complex, where our group has followed up on several sightings over the last few years. This logging road system extends about 60 km S from Hwy 1, following the Silver Creek drainage for around half its length, then cresting a pass and following the Skagit River flowing in the opposite direction to Ross Lake, which straddles the Canada/US border. The gravel main logging road is in typical spring shape, some nice smooth sections connected by stretches of shock eating potholes, often hidden in shaded areas where they're difficult to see before you shake your fillings out. At the first branch road, I managed to get 6km up the feeder creek before I met another 4x4 who had stopped because the wet spring snow at that higher elevation had halted his progress, even with chains on, so it was turn-around time for both of us.
Back on the FSR main, I continued south, until reaching a security roadblock at km 26, less than half way to my goal. The young woman at the gate explained that a recent wind storm had blown many dozens of trees down onto the road from that point on, and logging crews were clearing them, so access was closed till they finish up on Tuesday. So now I needed plan "B"
That entailed back tracking to Hwy 1, and turning south on the next watershed road system, which is a much steeper creek valley, but less well known, and less busy than my plan A trip. I only got 8 km in on this road, hitting heavy wet snow pack on the road at the 1,000M elevation (3300 ft), which stopped my H3 on a steep climb, so I hiked a little further up, till my old legs got achy, then returned to the truck, and headed home for supper. I scanned a lot of km of snow along the roads, without seeing any tracks at all, and no wildlife other than birds, but it was satisfying to get on the back roads again to try for that lucky break.
