Wow, what a heap of digging ...and look at the size of the field yet to be done Very good finds for a flat "mound", , , puts me right in mind of FRL digging towards the longhorns pasture .
You know I have to comment on "patina"....There's an interesting reason all except one is "bleached" white if you can figure it out. How about all the brokes ? are they predominantly white too ?
