For sure an interesting day in the Colorado high country. I also saw a picture on TV from near Eagle of what was described as a gustnado but in the picture looked more like a landspout. I got out on an interesting storm northwest of Pagosa Springs in the early afternoon. I noticed some interesting features with the storm. I think these were precipitation features, not a funnel cloud or tornado, but I was not completely sure at the time.

In the picture above, just below and to the left of the center of the picture, you can see a dark lowered feature coming down from the updraft base. While it has the shape of a funnel and I suppose could have been, I think it is more likely that it is a precipitation feature. But I am not 100 percent sure. Now look at this picture, taken a minute or so later:

In this picture, the original feature is still present just right of center in the picture, though more blurry - perhaps more hidden by precipitation between me and it, perhaps actually becoming more diffuse since I think more likely than not it was precipitation, not a funnel. But note also near the ground, a little to the left of where the aforementioned feature extends out of the cloud base, what looks like a narrow tube to the ground. At the time I was thinking possible landspout, so I grabbed my video camera, zoomed in as close as I could, and got a minute or so of zoomed but shaky video until the feature dissipated. In the video I cannot see any rotation, so I think it was a narrow, intense precipitation shaft, perhaps a hail column or a narrow column where the snow aloft melted into rain. So I am calling it a likely "fakenado." Definitely had me wondering at the time, though.
