Huell checks out a palm and a pine tree planted in the median of State Route 99 to signify the dividing line between Southern and Northern California. This starts a search for the exact geographic center of the state. In the process, he visits a couple of towns that claim to be "the center of California." With the help of locals and a cartographer from the U.S. Geological Survey, they determine the geographic center to be located southeast of the Madera County town of North Fork on the lower slopes of Castle Peak in the Sierra National Forest. With the quest completed, Huell proudly plants a state flag at the exact spot: 37° 9' 58.23" N, 119° 26' 58.29" W.
