Here is some beta. Don't completely rely on the accuracy of the lines drawn on the map. Since they weren't measured on a GPS, and we were trying to get out of there rather than study the situation, it is only an approximation.
Bachelor Creek Trail
Travelling in the downed timber for now is only slow. You can make it a little easier by travelling along the "flow" lines and reducing the number of times you have to cross downed logs, since it looks somewhat similar to the blast zone from the Mt. St. Helens eruption. Once the brush starts growing up to fill in the area, it only is going to get worse (lots of sky exposed now).
The creek is running pretty high, and is larger than you can easily jump across, like you would ordinarily do during summer. We made a log bridge near the last stand of trees before it opens up (remember, we were going down at that point so it made the most sense since we could follow snow to nearly that crossing point). Even at that, we wore crampons on the logs, and would have had balance problems without using our ski poles. With all of those aids, it was reasonably secure.
You don't want to fall into the creek right now.
