This is quite belated, but I am VERY busy and important after all... A couple weeks ago the whole Flathead Valley was mired in a soup of fog.
It was thick, gray, and dark on the valley floor, but just a thousand or so feet up, it was blue skies and sunny. So, even though the skiing was less than fabulous, it was sunny and hot, so up to the Big Mountain we went.
From there we went for a skin tour in the back country and got to spend the whole day up in the sunshine, climbing up through the slowly melting snow-ghosted forest and then skiing down in a fraction of the time it took to hike up, of course.
The lines we got to ski were actually pretty good. We did this two days in a row, one short hike, one longer - it was a Monday :)

This is a picture fromt the summit house at Big Mountain; the snow ghosts are the snow-crusted trees, they're melting and huge chunks of snow would just slough off.
In the distance, at the bottom of the picture is the soupy fog.

Here's another picture of the fog-filled valley from the sunny mountain top.
