Are all closed! I was in that area off 285 this past weekend and tried all of these.
Geneva Creek: Made it a few miles in, before snow-bashing was just no longer possible. I broke a bit of trail for the next guy, but my Nitto Trail 33's could only do so much before I was high-centered.
Twin Cone: Made it a ways up this trail, a lot of the switchbacks are pretty clear, just muddy. But once you get up high enough the snow is impassable. Even getting to the impassable part is impossible (ha) without at least 33" tires. I was scraping my undercarriage the whole way.
Boreas Pass: Closed at the gate.
Georgia Pass: Could not make it too far before the snow blocked the way. Maybe with another vehicle I could have gotten some speed to see if I could bust through some large drifts, but I was not up for that attempt solo. I know my max trax work, but I was not feeling like shoveling!
It's going to be a few more weeks before these trails can be run, unfortunately.
