Report 19804: Hunter reports unusual roars In South San Juan Mountains

The following is a report of unusual noises.  First, I would like to qualify myself as a competent woodsman...certainly no 19th century mountain man, but one who knows his way around the outdoors.  I was camping in the Rio Grande National Forest in Conejos County Colorado in September of 2005.  For those famaliar with this geographical area, I was in a district of the forest known locally and on topo maps as 'Jacob's Hill.'  I have hunted and camped in this area for many many years.  It was in late September and I was sitting in front of my campfire around 9 pm when I heard the most bone chilling and indescribable wailing roar that I have ever heard.  It was a very throaty sound and could best be described as an animal in agony.  While I have never heard a mountain lion roar in person I have heard this and other "cat" noises on T.V. and this did not sound at all like those noises.  The closest thing I could relate it to would be the noise of a hereford bull bellowing....but it was not that either.  The sound continued uninterrupted for about 5-10 seconds and then ceased.  Immediately coyotes from several different locales in the vicinity began howling and yelping as tho very disturbed.  I did not hear the noise again during that particular outing. Now, fast forward 2 months into November in camp in the same location for the elk hunting season. Bear in mind that until this moment in November I had not mentioned this incident to anyone.  I awoke at 4 AM one cold morning and noticed that someone else was awake and had built our camp fire again.  Because I was going to get up in another hour or so anyway, I got up and stepped outside.  It was my brother prowling around and I asked why he was up so early.  He replied that he had gotten up to go to the bathroom and the weirdest thing had happened.  I interrupted him immediately and told that before he told me what had happened I wanted to tell him about my experience.  I related to him the very story I told above.  When I was finished my brother just looked at me in amazement and said that is exactly what he had just experienced verbatim; right down to the coyotes reacting.  He, like me, could not relate the sound to anything we had ever seen or heard.
