Yukon UFO "Mothership" Incident: December 11th, 1996

Posted by jkrog08, on August 01, 2009

Hynek Classification: CE1

This is a great case I want to present to everyone. This case involves over 30 eyewitnesses and plenty of documentation of what appears to be a massive UFO that appeared over the Klondike Highway in the Yukon Territory of Canada on December 11th, 1996. If you already know of this case then feel free to add anything of value, I am going to try and cover everything though. :) This incident took place in three separate towns along the 134 mile length of the Klondike Highway in Yukon Territory, Canada. The reported size of the semi-spherical UFO is over a mile in diameter, or bigger than a football stadium. Again, there were over 30 witnesses (22 interviewed so far) to this unbelievable event which all concurred on the size of the craft, as well the shape, and all other important facts. Before I start I would like to give courtesy and thanks to the site and the investigator Martin Jasek, for extensively documenting this case in the way ALL UFO cases should be done.

1. Fox Lake

This region probably contains the best testimony. It consists of 6 witness reports of a saucer-like UFO ranging in size from just under to just over a mile in diameter. The witnesses requested anonymity so they are referred to as “FOX” with a number. This whole Fox Lake incident starts at about 8 PM local time with the first witness “FOX1” driving on Klondike Highway along Fox Lake when he notices a light illuminating a long smooth surface. This witness also states that he saw a group of “rectangular lights moving over a hill to the east”.

Some sketches of what FOX1 saw:

Witnesses FOX2 and FOX3 were traveling along the highway (in two separate vehicles) about a half hour later (8:30 PM) and witnessed a huge UFO hovering over the frozen Fox Lake, obviously they immediately stopped their vehicles to further investigate the anomaly. Within minutes the UFO was almost directly over FOX2, the UFOs size was enormous. The UFO continued to drift towards and eventually behind the hill where it disappeared from view. Here are the witness drawings:

Near the same time that FOX 2 and 3 were observing this event FOX 4 and 5 (same vehicle) saw it as well from the southern end of the lake. They stated they saw many rows of lights slowly moving across the lake. They also stated that because they had a 2 year old child in the back seat they feared for the safety the child so continued about their way rather quickly. Here are their sketches:

(Stated object was 500-750 meters in length, this is in accordance with reports of the diameter of the craft)

A few minutes later, when FOX4 and FOX5 were passing the Fox Lake campground, they passed by two vehicles that were pulled over with two men outside looking up at the sky. They turned around and pulled over to talk to them. It was FOX2 and FOX3 carrying on a lively discussion, "What the ‘heck’ was that?" After a few minutes FOX4 and FOX5 left and eventually stopped at Braeburn Lodge about 34 km (21 miles) further up the highway. FOX4 walked into the lodge and said to Steve Watson, the lodge owner "Steve, I really need a coffee!" Steve replied "Oh, you must have seen what FOX1 saw?" In fact FOX4 recalled seeing FOX1 leaving Braeburn Lodge just as they got there.
On the sixth Fox Lake witness:
There was also a 6th witness to the Fox Lake sighting but it is unclear what time she had driven through the area. FOX6 was driving in the vicinity of Fox Lake when she noticed a glow on her dashboard that could not be accounted for by the interior illumination of her vehicle. She leaned forward to look up through her windshield and observed a large arrangement of multi colored lights. The interior lights in her car started to go dim and the music from her tape deck slowed down.

2. Pelly Crossing
(Witnesses known as “PEL”)

Around 8:30-9:00 PM, 2 hours drive north the town of Pelly Crossing were seeing this massive UFO as well. “PEL1”( Don Trudeau) was outside just northeast of Pelly when he saw a large row of lights come over the hill. When PEL1 pointed his flashlight at the craft the UFO accelerated speed directly towards him, until PEL1 covered the light with his hand, at which point the UFO came to a rest about 300 meters from him.

Again there was no sound at all coming from the object. A beam of light emanating from the bottom of the UFO swooped the ground once directly underneath the object. Was it a search beam? Looking for him? The UFO then drifted slowly to the right. There were other beams emanating from the craft as well; a greenish phosphorescent color beam shone horizontally out the front (right); two beams at the back (left) rotated slowly to a horizontal position. All the beams could be seen clearly as there were ice crystals in the air. PEL1 turned away from the UFO momentarily and ran across a small clearing. When he turned back to look at it, it was gone.

Around the same time as PEL1 saw the UFO PEL2 and 3 saw it as well as they were traveling north just south of Pelly. They saw “left to right moving rectangular lights”:

They pulled over at a gravel pit just south of the Village to get a better look and got out of their vehicle. PEL2 noticed that the Big Dipper was just above the row of lights and compared the length of the lights to the width of the Big Dipper. They were about the same length!
Because the witnesses noted the Big Dipper size relative to the UFOs light size it is possible to estimate the size of the craft. Here are the witness sketches:

The other witnesses of the Pelly Crossing Incident were from four women taking a short break from classes at a small college. They reported rows of lights traveling towards them with a slight northern vector. They reported the object as huge with no sound, here is their sketch:


The UFO then disappeared over the hills as it continued on its northerly course.

3. Carmack Village
(PEL3 Sketch)

The Carmack sighting was witnessed by two different groups of people comprising 9 total witnesses. The first group spotted the object while driving in their pick-up truck south of Carmack. When the four men in the truck spotted the object they pulled over in a landfill to better observe the UFO, which was moving noiselessly northeast, then curved around them to the south where it proceeded to “vanish” from view near a microwave tower in the hills.

At one point the UFO was partially obscured behind a nearby hill and one witness recalls the UFO slowly reappearing on the other side of it. He remembers waiting a long time for the last light to reappear from behind the hill; that’s how slow and large the object was! The object took up about a 60 to 90 degree horizontal chunk of the sky.

The second group that spotted the craft was a family of four that spotted the craft outside their home window. They stated that the UFO made no noise as it silently crossed the tree line moving northwest to northeast. The UFO eventually seemed to ‘blink off’ and was not seen again by the family after this. Here is an interesting perspective on the sighting:

With the UFO sighting occurring just two weeks prior to Christmas, the three children thought that it was Santa Claus and his reindeer in the sky.
LOL, just goes to show you how the young human mind works.

How Big Is BIG???

Even with the lack of humans’ ability to accurately judge objects size at distances over 30 feet a method called triangulation can be used based on known reference points to very accurately judge a objects size. Luckily in this case the UFO was against MANY reference points seen by MANY witnesses. Based on this principle we can estimate the range of possible sizes of the UFO according to various witness statements and perspectives.

Given the information known by witnesses it has been calculated that the range of sizes for the UFO is the following: Anywhere between .3 miles to 1.3 miles in total size!

Obviously given either end of the spectrum the UFO was ENORMOUS by any stretch.

4. The Investigation

This case has been heavily investigated only by local UFO researchers (namely Martin Jesek) and documented by NICAP, NOUFOS, and MUFON. This area is not a heavily populated region and the sightings happened relatively late at night. While some witnesses did contact local radio stations and describe the event the others had to be tracked down. Even after witnesses were found most wanted to remain anonymous (the reason for the odd witness names), with some not talking at all apparently.

• 7:00 PM - UFO witnessed by 3 Carmack witnesses. Moving initially NNW then changing to NNE. 
• 7:45 to 8:15- UFO witnessed in Fox Lake. 
• 8:23 PM- UFO in Fox Late witnessed by multiple witnesses moving NNW. 
• 8:30 PM- Sighting by two witnesses stopped in the road at Fox Lake, object moving west to east. 
• 8:30 PM- UFO seen in Pelly by many witnessed moving in various directions. 
• 8:50 PM- UFO seen by witness in Pelly moving various directions. 
• *Evening- UFO seen by family in Carmack going NNW. 
• *Evening- “FOX6” also saw the UFO, the exact time is unknown. 

*Exact time unknown 

- There are reports from other towns and other witnesses that still need to be substantiated if possible. 
- Total time of sighting appears to be from 7:00-10:00 PM. 

The investigation is still ongoing but given the shear number of witnesses and reluctance for many to be made public it is (in my humble opinion) unlikely this case is a hoax.

Interesting piece of information:

There is also some evidence to suggest that this "sighting event" encompassed an even larger area as UFO reports were heard on CBC North radio the very next day mentioning sightings in the communities of Dawson, Mayo and Watson Lake. No witnesses from these additional communities have thus far come forward or been identified.
Unfortunately this case is not to wide known throughout many people, so it has not received the necessary attention that this monster case truly deserves in my opinion.

5. Alternate Explanations, Official Conclusions,
and My Conclusion

Alternate Explanations

There a limited alternate explanations currently available to this case. Of course it is possible that the sighting could have been some type of rare magnetosphere phenomena, a mirage, or something else that is currently unknown to science, or possibly an experimental government craft (although I know of none that would fit this description). These are all low probability in my opinion however. No blimps were known to be in the area, so unless this was an experimental blimp this is unlikely.

Official Conclusions

This case is still pending official review to my knowledge and therefore lacks any official explanations.

My Conclusions

In all honesty this is likely one of the top cases I have ever researched. The shear number of witnesses and the description of the massive UFO makes it hard to believe this was a misidentification of a prosaic event or hoax. Also the numerous other sightings in this region give credence to truly unknown activity going on. Another important thing to note is the commonality between witnesses spread out over 134 miles in their description of this UFO. Given that I think it is beyond highly unlikely that this is a hoax. Also the common dual nature of physical description(ie; shape and overall material look) and light pattern description of the UFO over 20 plus confirmed witnesses gives this case attributes that few have. So given the evidence currently known I would have to say it is far more likely that this UFO was a physical (and likely non-human made) object rather than a mirage, aurora, or hoax. But it could be anything in the long run, you never know for sure—although I personally think this case is extremely legit, I can’t rule anything out until further investigation is conducted. I would have to say I am about 98% sure that this was a TRUE UFO, was mechanical, and does not match any known or theorized human made craft or natural events. This case truly deserves MUCH more attention than it has received, so I hope that it gets it sometime soon.
