S.C. Tours are a public service and therefore free of charge. Tour groups include school, professional and civic organizations. Groups range in size from 20 to 80. Tours must be scheduled at least six weeks in advance.
More lead time is recommended.
Participants in tours of on-site field research areas must be at least 16 years of age. Security badging is required for on-site field tours, thus participants must furnish information on their full name, address, Social Security number and citizenship.
