pain of death if they ever returned. Twenty-two individuals were accused, informally tried, and hanged by the Vigilance Committee (the Montana Vigilantes) of Bannack and Virginia City. Nathaniel Pitt Langford, the first superintendent of Yellowstone National Park, was a member of that vigilance committee. A number of mining camps dotted the banks of Grasshopper Creek during the gold booms, starting at Bannack downstream almost to where the stream joins Beaverhead River. While many were short lived and considered just extensions of Bannack, others were designated towns of their own. Yankee Flats adjoined Bannack and was referred to as an "addition" to Bannack. Centerville and Marysville, about downstream, were both laid out as little camps in the winter on 1862. By the following March, a townsite company had laid out and platted Centerville. However, Marysville, named for early arrival Mary Wadam, gained more people and so contemporary maps alternately used the name on record, Centerville, or the name used by locals, Marysville. Dogtown was south of and "near" Bannack in 1866. It was named for the numerous stray dogs, and had a blacksmith shop, saloon, and grocery store. Jerusalem (also New Jerusalem or Jerusalem Bar) was located downstream of Bannack. Bon Accord, about downstream, was a larger camp that saw a revival in the 1890s, and had a post office and school district. White's Bar, located possibly downstream, was where John White and Company made the initial discovery of gold in 28 Jul 1862. State park Sixty historic log, brick, and frame structures remain standing in Bannack, many quite well preserved; most can be explored. The site, now the Bannack Historic District, was declared a National Historic Landmark in 1961. It joined the roster of Montana state parks in 1954. Volunteers work in conjunction with the state to preserve the fabled ghost town. Bannack Days Every year, during the third weekend of July, this abandoned town witnesses a historical reconstitution known as "Bannack Days". For two days, Bannack State Park officials organize an event that attempts to revive the times when Bannack was a boom town, re-enacting the day-to-day lives of the miners who lived there during the gold rush. An authentic, old-fashioned breakfast is served in the old Hotel Meade, a well-preserved brick building which was for many years the seat of Beaverhead County, before it became Dillon, Montana.
