Final answer:
The query likely refers to historical transport between states during westward expansion. Specifically, the First Transcontinental Railroad linked Sacramento, California to Omaha, Nebraska, with a significant connection at Ogden, Utah, during the latter part of the 19th century.
Step-by-step explanation:
The pony in question does not seem directly related to a historical event, but given the context provided, it appears the question may be referencing transportation between states during the time of westward expansion in America. The First Transcontinental Railroad was a monumental project that connected Sacramento, California with Omaha, Nebraska. Alongside wagon trails and the influx of population due to events like the Gold Rush, this period marked significant growth and migration in America's history. Specifically, the railroad connected to Ogden, Utah, which then linked to other lines reaching to the East and South.
It is worth noting that there is also a reference to Eadweard Muybridge's photography of a horse named 'Sallie Gardner' at Leland Stanford's Palo Alto track, providing a slice of related history during the era of westward expansion and development, particularly connected to California.
