Last Sunday, I made a trip to the South Platte River at Foxton. Having visited the river farther downstream at Waterton Canyon two weeks earlier, I did not know what to expect. After arriving at Foxton, I found thick slabs of ice covering most of the river!
Working my way along the river, I found a place that allowed me to get reasonably close to the flowing water. I made the following image with a 5 second exposure. This gives a milky white surface to the flowing water, just below the ice.
Here is another image of the ice above the flowing water.
Heading downstream, I noticed the setting sun lighting up the pine forests. There was one spot where the ice had melted, leaving a pool of water. The sun was lighting up the trees on the far bank of the river. Reflections of the trees in the water looked like they were covered in fall colors!
I made the following image of the pine trees catching the last sunlight of the day.
