Phyllis A. Whitney: Secret of the Haunted Mesa

Secret of the Haunted Mesa was published by Signet in December 1977. Author Phyllis A Whitney sets a story at a ranch in Arizona where Jenny and her friend Greg find an Indian boy who is stealing carvings and things from the ranch. When they inquire further, they find a mystery that is surrounded in the old Indian ruins nearby!

Allan Kass creates a scary cover for this photo with the menacing figure behind the teens who are out late at night sleuthing. I like the use of turquoise and the 70's feel of the clothing.
