Field Notes

Today I am happy because it is an early release Wednesday. Some things I saw at the pond were trees changing colors a birch tree fallen down into the pond, stores across the street (forest avenue) a trail that leads back into the woods, there is more growth on one side of the pond. I hear traffic on forest avenue next to me. I smell what I think of as "Fall", a nutty dead leaft kind of smell. One thing I am surprised about is that I didnt find more trash, Some problems I ran into was that everyone was really loud and that it took forever to get to the pond.

Smelling fall

I know exactly what you mean when you say that it smells like fall. Nice description of something that's really hard to describe!

I agree that you did not find slender naiad. Your evidence supports your claim nicely. Looking at your evidence photos, I think you may have found the stalk of a cattail. What do you think?
