Bluff Cemetery is a rural cemetery down a rural dirt/gravel road in north Barton County. There is only one way in from the south and I probably wouldn't want to be on the road after a big precipitation event. To the north of the cemetery is a private park. That is not where the cache is and remember that the area to the north is private. Latch the chain to the cemetery gate carefully.
You will be looking for a quart size jar that is camo'd. There is room for some trade items for you to add. Since this is a cemetery, you should NOT visit after dark - so daytime searching only. The cemetery is kept mowed so there should not be any bushwacking but ticks and chiggers are always possible.
