1970 - The greatest natural disaster of record for Arizona occurred. Unprecedented rains caused rivers in central Arizona to rise five to ten feet per hour, sweeping cars and buildings as far as 30 to 40 miles downstream. Flooding claimed the lives of 23 persons, mainly campers, and caused millions of dollars damage. Water crested 36 feet above normal near Sunflower AZ. Workman's Creek was deluged with 11.40 inches of rain in 24 hours to establish a state record. Moisture from Pacific Tropical Storm Norma led to the severe flooding.

Johnson Siding is an unincorporated community in Pennington County, South Dakota, United States. The population as of the 2020 census was 614. It is located in the Rimrock Area, approximately 10 miles west of Rapid City. Johnson Siding is surrounded by the Black Hills National Forest. It is the only significant business district in the Rimrock Area, with a gas station/general store, deli, casino, tavern, the Johnson Siding Volunteer Fire Department firehouse, the Rimrock Evangelical Free Church meetinghouse, and a community center. However, most inhabitants work in Rapid City or Deadwood.
Johnson Siding is named for a siding on the old Rapid City, Black Hills and Western Railroad (the Crouch Line) which ran up Rapid Creek between Rapid City and the Black Hills Highline at Mystic, which was originally constructed to serve the Johnson Sawmill, located a short distance upstream from the existing town.
Johnson Siding is located on South Dakota Highway 44 at the intersection of Norris Peak Road, a paved county road, which connects the Rapid Creek valley with the Box Elder Creek valley, and Nemo Road to the north.
Johnson Siding was the site of the political convention which first organized the South Dakota Libertarian Party in 1992, at which Costas "Gus" Hercules was nominated to the U.S. Senate. Johnson's Mill was also the head of the Hisega Flume, a wooden waterway constructed high on the south cliffs of the Rapid Creek canyon to supply a small hydroelectric plant at Big Bend near present-day Thunderhead Falls in the early 1900s, one of several National Engineering Landmarks in the Black Hills. This small Dakota Power plant delivered electricity to Rapid City until the community's needs out-grew the plant's capacity. It was shut down in the late 1930s. Dakota Power became a part of Black Hills Power and Light, eventually becoming Black Hills Corporation. A few remnants of the flume are still visible high on the south side of the canyon at the big curve of SD Highway 44 before one gets to Johnson Siding.
