The Girl Scouts of the USA turns 110 years old on March 12, 2022.
In the 1930s, individual Girl Scout troops began to group together as councils or associations.
Adults worried over how to keep older girls engaged, and GSUSA responded with innovative programming.
High school girls now had their very own membership pin, whose design inspired the Gold Award pin. The successful Mariner program would lead to other challenging programs for Senior Girl Scouts, including wing, horseback, and hospital aide.
The entire organization also began to incorporate civil-defense activities, which would come in handy in the 1940s.
