Thanks in advance for your help. I found this today down by the river. It has some unusual lines and a round ridge that I wasn't sure if it is man made or nature made. The rock is sandstone. Bottom is fairly flat as you can see in pics 2 and 3 as it is standing on it's on. In pictures 2 and 4 you can see the 2 lines on the one side. In the other pictures, you can see the rounded part. In picture 4 at the bottom of the rock by my finger, that is the rounded part of the rock that is in the middle.
