In 1888 it was moved two miles north to the terminus of the Vaca Valley and Clear Lake Railroad, and the name was changed to "Rumsey". The name "Rock" was after a rock landmark, and the name "Rumsey" was given after Captain D.C. Rumsey who owned the land at the time.
Cache Creek was temporarily blocked north of Rumsey by a landslide caused by the 1906 San Francisco earthquake: "Our Rumsey correspondent mentions the fall of Cache Creek as a result of an earthquake shock Tuesday night. The water has continued to fall some since that date and in some places it is dry. Upon investigation by the officials of the Water Company it was found that a landslide had dammed the Creek near the Leonard ranch in Lake county...." The creek subsequently broke through, causing severe flooding in Rumsey.http://www.yolocountyhistory.com/items/show/2554 Damage caused at the Rumsey Depot Caused by 1906 earthquake and resulting flood. The earthquake created a rock slide which blocked cache creek. The resulting floodwaters washed out the Rumsey Depot. Several damaged buildings are visible in the picture.http://www.yolocountyhistory.com/items/show/2555 .. Trees have been toppled over and are being pushed downstream by the floodwaters.
