Minnehaha on the rocks

_MG_0364.JPGSome of you might remember my first visit to Minnehaha Falls in June, when it was tumbling over a verdant cliff in a lush valley. Six months later, a good snowfall and a week of freezing temperatures have given the 50-foot falls a set of icicles almost as tall.

I went Minnehaha Regional Park last weekend right after that snow arrived and saw miniature snowmen and snow-plastered trees. But the creek itself was almost completely clear of ice.

The ice’s surface often looks topographical, forming stair-step terraces, sometimes a few feet tall, that remind me of terraced rice fields or canyon walls. Instead of wearing away at these canyons, the water has built them.

_MG_0395.JPGThose white blobs are bubbles that continuously flowed through what looked like a 4-foot-long, crystal-clear ice straw.

_MG_0425.JPGIt can be hard to see with transparent ice, but the shot above shows a good example of the terrace sets I saw: maybe 3 feet tall and stepping down from the upper left to lower right, with water gushing on the left side.

This last shot is what looked to be another set of terraces somehow under the water, giving them a distorted and unreal appearance.
