Question: The General Jesup was a steamboat that was launched on what river that starts in the Rocky Mountains?
Sentence (from "Rocky Point, Montana (ghost town)"): During the Missouri River steamboat era (1860s to 1880s), the buffalo trail system leading to and from the ford caused Rocky Point to become a steamboat landing, which received freight for mining camps in the Judith Mountains (to the south) and in the Little Rocky Mountains (to the north) and also for Fort Maginnis built in 1880.
Relevant evidence: No
