In this Aug. 6, 2019, photo, Robert Wolf, of Fort Dodge, Iowa, sits among the boxes of rock specimens he's donating to the University of Iowa. Wolf has spent a lifetime collecting the specimens in Iowa and he's carefully cataloged each piece. He also donated part of the rock collection to the University of Pittsburgh and his book collection to the University of Northern Iowa. Wolf is moving into an apartment and no longer has room for the collection which he's taken a lifetime to build. (Hans Madsen /The Messenger via AP)
