The Lewis & Clark Expedition
The Lewis and Clark expedition through central Idaho in 1805 was the first recorded exploration by people of European descent. By 1809 David Thompson established the Kullyspell House trading post on Lake Pend Oreille. The hunters, trappers, traders, and Iroquois guides who frequented the Kullyspell trading post reported that there were places in the far north and the east where people were teaching Christianity. In 1740, years before Lewis and Clark's arrival, Coeur d'Alene tribal leader Circling Raven had a vision and prophesied the coming of the Black Robes (priests).
Cataldo Mission Establishment
In 1842, Circling Raven's prophecy was fulfilled when Father DeSmet arrived. The first Jesuit mission was founded in near St. Maries and then moved a short time later to its present Cataldo location. The Mission of the Sacred Heart (Cataldo Mission), located on the Coeur d'Alene River, was completed in 1853 and is the oldest standing building in Idaho today. Shortly after the Cataldo Mission was established, the military arrived.
Military Arrival
Between 1858 and 1862 the Mullan Military Road was built, connecting Fort Benton, Montana, and Fort Walla Walla, Washington. Camp Coeur d'Alene (later changed to Fort Sherman) was established in 1878 at the point where Lake Coeur d'Alene flows into the Spokane River. The purpose of the Fort was to keep the Mullan Road open (built between 1858 and 1862 and connecting Fort Benton, Montana and Fort Walla Walla, Washington) and to keep peace between settlers and Native Americans. When the Fort was abandoned in 1901 there were 52 buildings, including a:
- Blacksmith Shop
- Carpentry Shop
- Chapel
- Hospital
- Sawmill
The chapel, powder magazine, and one officer's quarters remain standing.
Mining Activity
A community developed around the Fort, but it was not until the discovery of gold in 1883 to 1884 on Prichard Creek, on the North Fork of the Coeur d'Alene River, that many settlers arrived. Mining activity created an economic basis for future developments in timber, transportation, and trade in Kootenai, Benewah, and Shoshone Counties. The lasting wealth was not in gold but in lead, silver, and zinc, all of which required a large capital investment to process and mine. In 1883 the Northern Pacific Transcontinental Railroad crossed North Idaho. Rathdrum developed as an agricultural center and supply point for the mining district and remained a railhead until 1886, when D.C. Corbin built a spur line from the Northern Pacific mainline, at Hauser Junction, connecting to Coeur d'Alene. From Coeur d'Alene, passengers traveled by steamboat up the Coeur d'Alene River to the Cataldo Mission, where they boarded the narrowgauge railroad that carried them to the mining districts.
