Indiana’s highest point, Hoosier Hill, is a nondescript area in the woods of Wayne County. Perhaps the hill’s biggest claim to fame is that it was the last place Arthur H. Marshall visited in his quest to visit the highest point in the lower 48 states. Marshall is believed to be the first person to visit all 48 sites, making him the first known “highpointer”.
