Ok, we are back.
Well,
We found out everything ourselves!
The Cascade River road is closed by Dept. of Transportation around mile 6 with a sign. The road becomes impassable to street cars and maybe 4wd after mile 17-18. So we walked in ~8 miles. It is close to a disaster over there: ruined bridge and rock-slide block after mile 20.
Gosh, it was too warm and too much snow. We got to the trailhead on the 2nd day's early morning swimming in snow to our waists. It was too miserable to continue.
On our way back, it has become even warmer and we struggled to pull our car (slipping on dirt) out of the park. Fortunately the road got somehow plowed just about 1/3 mile back of the place where we abandoned our car (mile 16).
Getting there was fun, but getting out was even more so!
We did not waste our trip completely though.
We skied 2 days on Mt. Baker in fresh powder and climbed Smith Rock for 2 days.
Happy thanksgiving, ya all!
