In 1878, local farmer Alonzo Young established a boat landing on the Yellowstone River several miles east of here, and he and his wife also operated a stage station on the road to Coulson and Fort Keogh, along with a restaurant and hotel accommodations for travelers. An advertisement for Young's Point praised their strict attention to travelers and promoted the area's hunting, fowling, and fishing, calling it a splendid summer resort. Young's Point had a post office from 1878 until the Youngs moved it to the new community of Park City in 1882. That year, settlers from Ripon, Wisconsin, arrived in prairie schooners and settled near the mouth of Valley Creek about seven miles east of here, planting trees and making improvements to beautify what they intended as their future home. The Northern Pacific Railway donated land, established a station, and officials proposed the name Rimrock after the sandstone bluffs north of town, but the settlers held to the name Park City. In retaliation, the general manager of the N.P. changed the location of proposed railroad yards and shops from the townsite to Laurel. For a short time in the 1860s, fleets of Mackinaw boats traveled the Yellowstone River carrying passengers and cargo downstream to the States, offering a trip of about a month instead of several months overland. Built near the Great Bend of the Yellowstone near present Livingston, these flat-bottomed boats could be up to 50 feet long and 12 feet wide, with crews of five. The first boats sailed in September 1864, and more passengers followed in 1865, including territorial judge Hezekiah Hosmer and his family. His son Allen later published A Trip to the States, describing the voyage and the passengers' fear of attack by Northern Cheyenne and Lakota Indians during the war that had erupted along the Bozeman Trail. Although Hosmer's trip was relatively uneventful, other voyages in 1866 and 1867 were less fortunate, and by 1868 river boat traffic had nearly ceased because the violence had made travel too dangerous.
