In the ice fields northwest of Greenland in 1906, Arctic explorer Robert E. Peary spots a line of mysterious peaks dotting the horizon. He names that uncharted territory "Crocker Land," and years later, two of his disciples, George Borup and Donald MacMillan, take the brave steps Peary never did: with a team of amateur adventurers and native guides, they endeavor to reach this unknown land and fill in the last blank space on the globe. Illustrated with 16 pages of photos, David Welky's history is a chronicle of hardships and mishaps beyond anything the explorers could have imagined, from howling blizzards and desperate food shortages to murder.
