In the mid-1850s, the county seat of Yolo County, California was moved from Washington to a locale called Hutton’s Ranch where the post office was called Yolo. At that time, the name of the town was changed to Cacheville. In 1862, when the county seat was moved to Yolo City (which was then renamed Woodland), Cacheville became known as Yolo.
All this history and more can be found on the web in the Yolo County History chapter of A Memorial and Biographical History of Northern California - Chicago, Lewis Publ. Co., 1891.
This cache is located along Cacheville Road on the outer edge of the town of Yolo. The road is busy and it has been recommended to us that we mention to folks that they keep the kiddies in the car for this one. Use "Exit 542 – Yolo" to access the area. Our Cacheville Branch of the Yolo County Library GC10CMV and a couple other caches are also available nearby.
