Besides the brown grass here is another sign that sometimes happens when there hasn't been any rainfall in a while. I saw this yesterday just above Dogtrot on the road while I was going to check on a neighbors camp. They usually travel downhill in search of water from the higher elevations. I would estimate the length to be between 4-1/2 & 5 feet and the diameter was around 3" with a button array of about 10.
