Elwood (Box Elder) is on US-30S, two miles southeast of Tremonton. It was established in 1879 with an early name of Manila Ward in honor of Commodore George Dewey's victory in the Spanish American War. The name was changed to Elwood by the postal authorities to avoid confusion with the Manila Voting Precinct. Mr. Davidson, a cattle and sheepman, was the first white settler in elwood.
