George, as far as the two symmetrical features go, I don't see a scale so I don't have any idea how high they are. The closest natural features on Earth could be formed from glacial deposits, such as eskers, drumlins or kames. However those types of features are not generally symmetrical. I do not know what could have generated those mounds in such symmetrical shapes so close together by a natural process. The closest thing I can think of is mounds formed from stockpiling sand and or gravel when the material is dumped or flowed through a pipe or chute from above.
