The assay office still stands (adjacent to the Folsom History Museum) and is a California Historical landmark.

From July 1, 1861, until the last letters were delivered in November 1861, westbound Pony Express riders ended their horseback journey at a corral beside the Wells Fargo assay office/relay station in Folsom. (The Folsom History Museum now stands at the corral location.) There they left their horses, transferred the mochila to a train bound for Sacramento, and then boarded a river steamer to San Francisco. Eastbound riders made that rail-and-river trip in reverse, retrieved their pony at the Folsom corral, and continued east with the mail on horseback.
This arrangement made Folsom Station—specifically the Wells Fargo assay office—the western terminus of the horseback Pony Express during the operation’s final five months. On 2 occasions, when the rider missed the scheduled train, a railroad handcar carried the rider and mochila the 22 miles to Sacramento. Either way, the horse stayed behind at the Wells Fargo corral, making Folsom the true end of the trail, even though the mail continued to San Francisco.
Today, the former corral site is home to the Folsom History Museum (823 Sutter Street), where visitors can explore exhibits on the Pony Express, local Native tribes, and nearby Folsom Prison. Behind the museum, the spring where the mail horses once guzzled cold water now bubbles into a concrete trough. Next door, and part of the museum complex, is the original Wells Fargo Assay Office, which served as the official Pony Express relay station. It is designated as California Historical Landmark 702.
The museum is also where riders re-enact handing off the mochila during the National Pony Express Association’s annual commemorative re-ride each June. To watch the mochila exchange, check the association’s website for the schedule.
After visiting the museum, head to The Square to try gold panning, watch a blacksmith at work, and experience more of Folsom’s history. The Folsom Railroad Museum, located at 198 Wool Street, is also a popular attraction.
