YEAR: 1991

SEASON: Fall

MONTH: October

DATE: 25-30

STATE: Arizona

COUNTY: Coconino County

LOCATION DETAILS: We Were camped at a location listed on the maps as "Big Saddle". It is about 1/2 mile from the north rim of the Grand Canyon. The only two ways into this area are from the 89 near Page, az. or coming south from Utah and going through Fredonia. The area is a maze of fire and logging roads.

NEAREST TOWN: Fredonia or Jacobs lake lodge

NEAREST ROAD: 89a

OBSERVED: I'm not sure if this is what you are looking for but it is the only thing that strikes my memory when I think back about things I've heard while in the woods. After listening to the sounds you have listed on your site I realized the ones I heard were very similar. I was 15 and my family and I were on a hunting trip in the north Kaibab region of Az. We were there for 4 nights and 5 days. At the end of each day just as the sun was behind the ridge but not quite down we started hearing a high pitched whoop sound. The sound came as a double whoop(whoop,whoop). It was a little higher pitched and shorter. It could be heard from the ridge just west of our campsite about a 1/2 mile or so away. The sound continued for about 2-3 hours or until just after dark. It also sounded as if it was moving around on the ridge and maybe even coming closer as it got louder several times. there was about 30-40 seconds in between each set of whoops.
On the second night the sounds started again just like clock work from the same area on the ridge but this time they were answered by another on the ridge just to our southeast. the second sound was alot closer and it would return or answer the one from the west about 1-2 seconds after it would sound. this went on the rest of our trip only from dusk to dark each night. On one of the evenings there was a third whoop that answered in from the north but it seemed farther away and only answered every 15-20 minutes. This made me remember how my father had been hunting in this same spot about 4 years prior and told me how his cab over camper was rocked several times in the night. Each of his hunting buddies swears it wasn't them as they were too drunk to get up and were afraid of what my father slept with for protection. I hope this helps some.

OTHER WITNESSES: My entire family including me of 8 people.

OTHER STORIES: Just my father incident about 4 years prior in the same camp spot as mentioned above.

TIME AND CONDITIONS: early evening to dark. there was an early winter like storm that rained on us in the lower lands but snowed in the higher areas.

ENVIRONMENT: The area of our camp was inside the depression of three small ridges one on the west, north and south east. The area is dense Ponderosa Pines, scrub Oaks and Manzanita. You can go to the rim of the canyon and watch the deer coming out of the canyon or going into it to hide.

Follow-up investigation report by BFRO Investigator TF Zamiski:

I spoke with the witness on 3/27/2006. He has been very interested in this subject since this incident. There are similar sounds he listened to on this website which prompted him to post this report. The vocalizations heard on this trip seemed to come from multiple sources in apparent response to each other and on consecutive evenings. In this report he describes high pitch whoops but he added during our discussion that they were almost "whistle like" and as though the sound came from the throat and not a typical whistle like we would do.

This area is a popular for deer hunting and he has been there several times over the years. He is also familiar with animal sounds of this region, this was something very different.
