Noble is considered the "Rose Rock Capital of the World", as the concentration of barium sulfate in the soil is higher there than anywhere else, causing the formation of rose rocks.
In honor of this status, Noble sets aside the first Saturday each May to celebrate its annual Rose Rock Festival. Local geologist Joe Stine and his wife opened the Timberlake Rose Rock Museum in 1986.
