To be able to open the cache, head through the portal and use the clues provided to find the combination:
Head to the main desk and locate the three glass, mosaic panels
A = The number of years listed at the bottom of the middle panel
Find the bulletin board with news clippings about Pauline Robinson
B = The first year when Black History Week was created, MINUS the year she received her Librarian of Science Degree
C = The year Pauline Robinson was first listed as a "Who's Who in Library Services"
Now locate Pauline's trunk at the top of the large blue cabinet. Carefully remove the trunk from the top of the cabinet and open the lock using the combination:
C - (1774 + B + A)
PLEASE BE SURE TO REPLACE THE LOCK AND CONTAINER PROPERLY WHEN YOU'RE FINISHED!
This cache series would not be possible without the enthusiastic and supportive help of the staff at the Denver Public Library! To celebrate the series, DPL has released a passport program! The first 200 geocachers to legitimately log the series, record the secret codes found within their geocaches, and turn in the completed passports will receive a special, limited-edition Denver Public Library Geocoin!
More information can be found on the DPL web site. Happy Caching!
