You Guessed It: Glacier
We took the same trail I hiked on 6/24, except this time it was raining with a gentle intensity that defies clichéd descriptions of rain. It was neither driving nor pouring; nor was it lashing, tempestuous, or torrential. It did not come down in sheets nor did it let fall cats and dogs. The closest I can come to an accurate description is "a soaking rain." There was a lot of water falling from the sky, and though it was not joined by a great deal of wind, it saturated every fiber of both clothing and being after a little while.
It was temperate enough that I made the decision to forgo my raincoat. I didn't want to spend the walk fighting to stay dry with the hood up and the blinders on. I decided to be endued with water and to trust my high-tech clothing to block enough of the chill glacier winds.
Still, to see the areas on bare rock retreat a good ten feet and the area on the water retreat even more than that in only three weeks made it easy to believe that global warming is melting the glacier faster than a normal post-ice-age retreat.
A snowflake is a typical ice crystal; a freezer ice cube is a whole series of small crystals stuck together. In a glacier, the immense pressure, together with the melting and refreezing that typically take place, forces the smaller crystals into alignment, and they join up into larger crystals. Cathy commented that the blue, compressed ice has more of a mineral quality to it; the ice crystals are positively enormous, and you can see the water's true color.
I wasn't too much in geology mode. We got a good look at a Spotted Sandpiper, who flew back and forth, piping. He was probably trying to protect his unfledged hatchling, who made a break for it from one small stand of alder bushes to another.
We didn't stay so long at the glacier that the cold breeze coming off of it made me truly miserable in my wet high-tech gear. I was just comfortable enough to be truly content. Then a brisk walk back to the trailhead and off to a long, hot shower. I may have been philosophically inclined to get wet, but that didn't mean I had to stay that way.
