Near Kasson Road, ■ about a quarter of a mile south of Durham Ferry Road, a solitary brick pylon can be found. At one time, a plaque commemorating California Historic Landmark 777 was mounted on the pylon. However, like the city of San Joaquín, the place commemorated by the plaque, no trace remains today. In the spring of 1847, Captain Charles Imus and his family settled in this place. Here, the West Side printing company has created an ideal site for a farm. Elsewhere, a seasonal floodplain extended a half mile or more from the banks of the San Joaquín River. However, where the dry arroyo of Hospital Creek meets the river, the western bank of the San Joaquín is on higher ground and does not flood. An ancient hunting trail once followed Hospital Creek. Lieutenant Gabriel Moraga, during his exploration of the Tulare district in 1808, followed this trail from the hills. When they reached the river, Moraga's group set up camp before fording the stream to explore the eastern plain. Moraga, with Fray José Viader, returned two years later. Again, they camped on the same dry, high ground. About a mile upstream, the San Joaquín River meanders north, then turns sharply south again in a switchback meander. South of Sturgeon Bend, the name hunters gave the meander, the Stanislaus River flows into the San Joaquín from the east. Rich in wildlife, the place had long been home to a Yokut village. During the summer of 1827, Jedediah Smith's men camped near here, if not at this location. Impressed by the climate and abundant wildlife, Smith's group convinced Hudson's Bay Company hunters in the Oregon Country to begin hunting further south each year. From 1832 to 1845, French Canadian trappers established their seasonal headquarters in what they called Castoria [French camp] about fifteen miles…middle of paper…amending an Act entitled “An Act to Create County of Stanislaus”, approved on 1 April 1854, approved on 3 May 1854). Once again, Grayson stayed out of San Joaquín County. In 1860, as Tinkham reports, Stanislaus County annexed a portion of San Joaquín County. In a move known as the "Walden theft," Stanislaus County Assemblyman Miner Walden (1823-1916) planned the annexation of 110,000 acres of San Joaquín County land, including the town of Knight's Ferry. The landscape added to Stanislaus County was east of Escalon and north of the Stanislaus River between Knight's Ferry and Riverbank (STATHS OF 1860, Chapter 65, Act to annex a portion of San Joaquín County to Stanislaus County, approved February 17 1860). Once again, Grayson remained in Stanislaus County, and the 1860 annexation proved to be the last significant change to San Joaquín County's boundaries.
