While searching my 40 acres in southcentral Oregon, I found these buttons all in one hole.? 5 buttons all total.? This area used to be used for a ww2 training site in the early 40's.? They look like some kind of military button off an Army uniform.? Don't know why they would be all in one hole?? Didn't find any bones to go with them!? The buttons were about 6 inches deep.? Here are some attached pictures of the buttons.? They have 13 stars on them and are like new.? Absolutely no clue!? Does anybody have any ideas?? Thanks Earl
