'The Secret of Bigfoot' (Part 1) (Story Code '43027') by Kenneth Johnson

Steve is sent to the forests of Northern California to locate two missing scientists, Ivan and Marlene Becky; the husband and wife team mysteriously vanished while they were installing an earthquake warning system near a fault line. As Steve makes his way through the dense forest he finds a set of oversized footprints in the earth; he follows the trail and soon comes face to face with a giant, hairy man-beast. The creature attacks him, and a vicious battle breaks out, during which Steve tears off the monster's arm - and realises that the beast is in fact an android. The creature retreats to the safety of a cave, but when Steve pursues it inside, he is knocked out by the dizzying effects of the cave interior. When he comes to, Steve finds himself strapped to an operating table as a beautiful alien woman named Shalon prepares to study him…
