Adobe Walls was made of just that, adobe. It has weathered away so that nothing can be seen on Google Earth. Too bad. I too like studying 19th century American history. I have also driven near the area several times but never stopped to investigate. From the looks of the photo in the OP, I haven't missed much.
Wind in my hair, Sun on my face, I gazed at the wide open spaces, And I was at home.
