Its most important period was from 1863 to 1868. Despite the fact that the major part of the route in Wyoming used by all Bozeman Trail travelers in 1864 was pioneered by Allen Hurlbut, it was named after John Bozeman. Many miles of the Bozeman Trail in present Montana followed the tracks of Bridger Trail, opened by Jim Bridger in 1864.

The privately financed expedition was carried out by David E. Folsom, Charles W. Cook and William Peterson of Diamond City, Montana, a gold camp in the Confederate Gulch area of the Big Belt Mountains east of Helena, Montana. The journals kept by Cook and Folsom, as well as their personal accounts to friends were of significant inspirational value to spur the organization of the Washburn-Langford-Doane Expedition which visited Yellowstone in 1870.
The Washburn Expedition of 1870 explored the region of northwestern Wyoming that two years later became Yellowstone National Park. Led by Henry D. Washburn and Nathaniel P. Langford, and with a U.S. Army escort headed by Lt. Gustavus C. Doane, the expedition followed the general course of the Cook–Folsom–Peterson Expedition made the previous year.

Montana Highway 287 is a state highway in the U.S. state of Montana. The highway runs 42.822 miles (68.915 km) from MT 41 in Twin Bridges east to U.S. Route 287 in Ennis. MT 287 is the primary east–west highway of Madison County. The highway connects the county's four towns, including Sheridan and the county seat of Virginia City. The course of MT 287 follows the ultimate portions of two trails that met in Virginia City, the center of the Alder Gulch gold rush of the mid-1860s and the second territorial capital of Montana. Parts of the highway were improved from rudimentary roads around 1920 from Virginia City to Ennis. This connection became the first portion of Montana Highway 34 in the early 1930s; the highway was extended west to Twin Bridges in the late 1930s. MT 34 was reconstructed from Twin Bridges through Alder to Virginia City in the late 1930s and early 1940s and between Virginia City and Ennis in the late 1940s to mid-1950s. The MT 287 designation was first applied to a cross-state route from West Yellowstone to Canada in the late 1950s. The highway was rerouted in place of MT 34 in the early 1960s. MT 287 was replaced by US 287 along much of the cross-state corridor in the mid-1960s. The highway extended north of Twin Bridges to Whitehall until the late 1970s, when it achieved its current length.
