Walking Thunder is a 1994 film starring James Read, John Denver and David Tom and Bart the Bear, written and directed by Craig Clyde.
It relates the memoirs of a young boy Jacob McKay who travels with his family on a wagon on their way to California and become stranded in the Rockies.
Jacob McKay, a young boy, travels with his parents (John and Emma) and younger brother Toby in a covered wagon en route to California.
Jacob and Toby are sent to look for food and eventually reach a lodge owned by Dark Wind, an old Sioux medicine man.
Mountain man Abner Murdock, who understands the Sioux language, acts as interpreter between Dark Wind and the kids.
The family needs supplies to survive the winter, so Jacob is sent with Murdock to procure them from a rendezvous of mountain men which takes place days away.
Walking Thunder later appears to Richter, who attempts to shoot him, but a nearby Dark Wind first utters a warning call, and the bear disappears.
Richter attempts to kill Dark Wind, who is praying in the woods, but Jacob materializes behind him and tells him to put down his gun.
According to the Sioux, he was healed by Dark Wind and roamed with him the mountains until the day they were recalled by the spirits to their eternal after-life.
