Field Notes
why are there so many dead fish in one area? What type of fish are they? I see dead fish with insects eating them. I smell pine and hear people talking. I am surprised that we found so many dead fish because there are not usually so many

Very nice job on the pictures! I think you may have a blue violet versus a blue flag iris. On an Iris the flower is upright on the end of the stem, whereas on a blue violet it "nods". Essentially the end of the stem curves over and the flower is at the end of that. I would need to see a close up of the flower to know definitively. But this is a tough one!!! The iris and violet look very very similar. Keep up the identification! You were on the right track.

Hi MDSciGr3a,

It looks like your coordinates are slightly off from the Ducktrap River. Please leave a comment below with the correct coordinates and we will update them for you.
