It was the yellow snow that made me take a closer look. I knew it wasn’t urine because it was like a yellow shadow on the snow beneath the arched tree in the woods.
Then I saw moisture running along the bark and dripping into the snow.
From what I read, I believe it’s tannin released by the sharp change in temperature. Tannin is stored in the bark of trees and helps protect it from bacteria and fungi.
Interesting. I would have just assumed urine. Now I have something new to be on the lookout for when I’m in the woods.
It was around many of the trees on that day Trish. I think it has to be certain conditions.
