Clayton is located at the foot of Mt. Diablo State Park.
In 1857, the town of Clayton was laid out and founded by Joel Henry Clayton (1812–1872) and his two younger brothers. Clayton was born in Bugsworth, now Buxworth, in the United Kingdom, and emigrated to the United States in 1837. After years in other states he settled down with his wife Margaret (1820–1908) at his town at the foot of Mt. Diablo, where he and his family prospered. Clayton was named after Joel Henry Clayton, although only by the flip of a coin. Joel Clayton and Charles Rhine cofounded the town, and each wanted to name it after himself. If Charles had won it would have become Rhinesville, but Joel Clayton won. Joel and his wife Margaret both died in Clayton, and were buried in Live Oak Cemetery in what is now Concord, CA.
On December 7, 2009, it snowed in Clayton and nearby Concord for the first time since the 1970s.
On September 8, 2013, fire broke out on Mt. Diablo. The fire started at the mercury mine area of Morgan Territory Road. The fire grew fast and threatened homes and livestock. Evacuations were ordered for several areas including Oak Hill Lane and Curry Canyon. The fire was named the Morgan Fire. It took over 1000 firefighters and 8 helicopters/planes to put the fire out. Full containment was announced on September 14, 2013.
