SIOUX FALLS, S.D. (AP) — The planned auction of nearly 2,000 acres of land in South Dakota’s picturesque Black Hills that is considered sacred by American Indian tribes has been cancelled, though it wasn’t immediately clear why.

Brock Auction Company planned to auction five tracts of land owned by local residents Leonard and Margaret Reynolds on Saturday. But a message on the auction house’s website Thursday said it has been cancelled at the land owners’ direction.
