I took this one in October this year around the 16th. I stay in West Yellowstone and travel the loop each day to search for images. I was at this site the day before but it hadn't snowed yet. It snowed that night, so I returned and was delighted to see this. Hope I didn't make the image too large for the forum. I can downsize it if so, since I have it posted on my server instead of the forum.
I just joined the forum last week and have gotten a lot of information by browsing etc.
