You're going to have to go pretty high up to get to this one. No bushwhacking required, and I provided a waypoint for the "easier" trail that leads upwards (although you are welcomed to try to find another path that'll take you to GZ). Note that the trails are not marked but are fairly obvious.
Terrain is rather steep at points, and quite difficult if there is ice, snow, or even mud. Trekking poles might be advised if you want to attempt when conditions aren't ideal.
You're looking for a see-through ammo container.
PLEASE respect the fact that this is on State Gamelands, and as such precautions must be taken. Wear Orange when you need to, know when the hunting seasons are, and I advise not caching at all during peak hunting seasons. Respect the hunters who help pay to keep our gamelands well maintained.
I also encourage you to finish going up Round Top (maybe to find & log the benchmark marker at the top). After all, you hiked up all this way, you might as well get to see a view...try to see if you can spot Three Mile Island to the Southwest. Plus there's a bench at the top to relax and catch your breath!
If you are hunting only for this cache, I'd estimate the whole trip to take a bit over 1 hour
This is my first cache, so comments, suggestions & opinions are greatly welcomed.
