There aren't any active wells in the Hammersly that I know of. The gas activity on McConnell is shallow gas drilling, not marcellus. However, there is a marcellus well at the bottom of Horton Run near East Fork.
FWIW, my family killed 3 bucks in the HWA this year.
deer numbers were down in hammersly back a number of years ago when we hunted it. but we did alright..we hunted hard, covered a lot of ground..way before dark when we went in.. way after dark when we came out. the last time i hunted there i was still dragging at 8:00 at night.
