 In the summer of 1858 a group from Lawrence, Kansas, arrived and established Montana City on the banks of the South Platte River (modern-day Grant-Frontier Park).This was the first settlement in what would become the Denver Metropolitan Area.The site faded quickly due to poor findings by miners and most of the settlers and some structures moved north to the confluence of the South Platte River and Cherry Creek and formed a new settlement named St. Charles.
