I'm keeping an eye on trail litter this summer to see what's going on.
Last two hikes with results:
1. Adams via VW, Brookside, Watson, Scar, Airline, Gulfside, Lowes, return via Star Lake Trail, Airline. A few pieces (3-4) of microtrash and plastic, all smaller than one inch length.
2. Ammonoosuc Ravine Trail, first mile for trail work. Same thing - a few pieces of microtrash with one plastic bag, one cigarette butt.
My conclusion is that it's more than I like to see, but it's not an alarming increase over what I have seen in the past.
Here's a hypothesis: I spend most of my time on trail in the northern Whites. Is there more trash on southern trails?
