Please park @ the posted cords a proceed from there on foot. It is about 1/2 a mile to GZ. All but the last .13 mile quite literally a "walk in the park". Then the terrain rating kicks in, still a well defined trail. Cache is near the cave, just up the trail. No need to get near the edge. Add another 1/2 at least to the terrain if you want to go into the cave. Not essential, but I wouldn't miss it. NOT for the "faint hearted".
One of my favorite place to go years ago. Hiking, fishing, etc. Now camping with permission only. Nice view, cool spot IMHO.
Cache is a larger plastic jar containing log, stubby pencil, and $ for FTF. Plenty of room for track ables and/or trade items.
