For though's of you concerned... I talked to the Ranger station headquarters and they said this time of year you can pretty much camp anywhere. I asked about campgrounds and he said "Yep should be fine just clean up after yourself. Overnight parking is not an issue as long as you have your snopark passes.
So we are allowed to camp at Clear Lake with no issues.
Sorry have not been on much in a while. Work has been keeping me swamped.
