Talking recently about the cuneiform had me thinking about a close to home way of using images to communicate. We have multiple ranches that were indian lands during indian territory so you can find many treasures. We believe that these were probably done by Ed Galloway who did the Totem Pole. It is close to the representations of the ones on the side of the totem pole.
The first one is because of the trees behind this fort building. It is the stump which shows the amount of rings that were on the tree or maybe about the fertile years of the trees (they were pecan trees). There are multiple of these around the building so it has to be a way of counting. 
Here is another symbol on the side of a wall, It was on the side of a building that probably held potted plants in the barn during the winter. Also shows irises, which there are usually some there in the spring.
Here is my favorite piece, the fish is hanging from the tree that are around. The leaves are the same as the tree grove behind it. It was once painted purple, but it is going away quickly. The eye is made of some type of marble. This is special because there used to be a creek that had fish in it behind this area, but throughout erosion it has been dry for quiet a few years.
