Trap School is shown as District #24 in 1904, even though earlier schools existed in this area.  Later in 1904, Trap School was redefined as District #29 and covered about the same area as the Leaday School District #29, which was created in 1906.  This would make it appear that the school district was first named Trap (or Trapp) after the crossing on the Colorado River, but the name changed after the town of Leaday was established.
