COLD!

That's right.
This morning around 7 a.m. it was 8 degrees F with gusting winds.

The brook, where flat is nearly iced over with slushy water flowing partly on top of the ice and partly through the forming ice. Where the brook has falls it is still open, except at the edges.
As for the Cascades, well 8 degrees and below with winds all night (sometimes fierce) froze it up pretty solid by dawn. There is water running but it is beneath the ice.

By 9 a.m. the temp was up to 11 degrees with a humidity of 54% and winds still gusting.

By 11 a.m. the temp was up to 21 degrees and still rising, but the wind is still with us.

If you are going hiking, leave no exposed area at all, dress warmly, and keep moving!
