Man describes an observation near Sabino Canyon when he was 15 years old.

October 1975 late morning, between 10:30 and 11:00AM Tucson, Pima County, Arizona 1 witness

Account

The witness was hiking alone near the school campus in late morning when a strong odor and digging sounds drew attention. Through brush about 50 yards away, the witness saw a large gray-brown hairy animal crouched over a burrow digging with hand-like limbs and making grunting sounds. When it began to shift toward the witness, the witness fled to campus and reported the sighting to school staff.
