Memory told of being chased off by frightening thumps and scream while hiking in Pikes Peak State Park

Account

In September 1970 the witness and her husband were hiking a deserted trail in Pikes Peak State Park toward the Mississippi River overlook. From behind trees they heard extremely loud thumping sounds followed by an unfamiliar loud scream, without seeing the source. Frightened, they ran back to the ranger station to report what happened. Years later after watching television programs, the witness concluded the sounds were likely made by a bigfoot.
