Triangular objects moving East within fast moving clouds at Comer's Rock campground, Grayson, VAI drove up to Comer's Rock campground in the Jefferson National forest, which straddles the Wythe County/Grayson County, VA line. It rained for three days solid. On the fourth day, I was able to explore outside the tent and campsite. On the afternoon of August 24th, the wind shifted and the weather finally broke. I took the cot out of my tent and laid in the breeze watching the sky. A low level of cirrocumulous clouds approached from the West. Below these mottled clouds was another string of mottled clouds going in the opposite direction, which was fun to watch. The wind picked up and the lower Altocumulus clouds zoomed to the East. As I lay there looking at the sky show, I began to see triangular shaped objects inside the clouds. In the space between the cloud structures, there were several things that appeared to be solid triangular objects. Honestly, I was stunned and couldn't take my eyes off them. Perfect, clearly-formed triangular shapes almost hiding in the clouds. I felt totally mesmerized. Eventually the entire cloud bank passed to the East and I never saw anything unusual again that day.
