1. (possibly dated, slang) To explore; to go around exploring, to go around as an explorer.
   • 1921, Forest Leaves, volume 15, page lxx:

     No street car line passes it, so you'll have to do a little Columbusing on your own account-to find it-—but it's worth discovering, and President Gardner's phophecy sounds conservative.
