There is a yellow jacket nest on the north side of the loop trail about 3/4 of the way up. It is in a dip. Look for a dead tree (no top or bark) leaning north. AHP is known for it's yellow jackets. This year is no different.
There is also a hornet nest on the south look. It is shoulder height on a small tree. It is now about the size of a baseball. Bound to get a lot bigger and nastier.
If you want blueberries, you might have a little pain getting them. Bears have been up the north loop for the berries.
