Overflow ice pictures
We went for a walk up the creek with the dogs today, and the overflow is amazing. It's doing this incredible thing where it's lower in the middle and then goes up the sides. Way up the sides. Orion thinks that the creekbed is completely frozen and this is forcing the water to percolate through the ground and seep out the side of the hills, because it's forming these frozen cascades coming out of the sides of the valley.
... which of course I didn't have my camera for.
But when we got back, I went and got my camera and walked down onto the nearby stretch of creek to get some shots of the local overflow, because it's still pretty cool and kind of looks like flowstone or melted wax -- it's been so cold that the water freezes almost immediately when it wells up, so you can clearly see how the layers have built up.
A picture is worth a thousand words, though.
The ice on the main creek is doing that higher-at-the-sides thing too, just not as dramatically. It's sort of hard to demonstrate in a picture, but this picture is NOT tilted ... the ice in the middle (where Lucky the dog is standing) is quite a bit lower than at the sides.
Very dramatic color-shift between layers of ice.
Water welling to the surface has frozen almost instantly, making it look like flowstone or lava.
More flowstone ice. There were some pretty impressive cracks, too, including some going down several feet.
More two-tone ice, with dog paw for scale.
Frost feathers on the ice, with my hand for scale. This isn't snow, just frost that's spontaneously developed from the moisture in the air immediately above the creek.
More flowstone ice and frost feathers, again with hand for scale.

Lava, did you say?
Another picture (http://danbirchall.multiply.com/photos/photo/52/27.jpg), this one taken by my friend Dan.
Lastly, this is old (http://www.uhh.hawaii.edu/~csav/gallery/decker/hawaii_lava_arch.php) but no less cool for being so.
Hello my friends!
