'Trail to the Unknown' by Larry Spiegel

Doctor Zaius thanks Cornelius and Zira for stealing Urko's plane, which he believes has saved ape society from the threat of the General’s dictatorship. Meanwhile, Bill, Jeff and Judy work on the construction of rafts to help the humans reach ‘New Valley’ via the river. Using a map given to them by Cornelius, they make their way through a hot, steaming jungle, emerging into a desolate desert landscape, where they find the wreck of a United States spaceship, and its pilot, astronaut Ron Brent. He tells them how he left Earth on August 6, 2109 from a launch pad in the Mojave Desert, only to enter a time warp and crash on this world; after meeting a young Nova and her tribe, he decided to join them on their travels, but when he became separated from them, he returned to his ship and has stayed there in hiding for twenty years. Brent offers to show them the way to New Valley – unaware that Urko and his gorilla troops are not far behind them, determined to capture the humans at any cost…
