Written by Arthur Julian, this episode finds Hogan and his crew trying to harness the forces of nature in order to create an avalanche. It is all part of a scheme to redirect a full-scale Panzer assault, which has been routed through the slippery slopes of Mount Hoffenstein. Harold J. Stone heads the guest cast as General Stromberger. Originally telecast on March 21, 1971, "Look at the Pretty Snowflakes" was the last episode of Hogan's Heroes to be filmed, though not the last one to be shown. ~ Hal Erickson, Rovi
