"Description: Please take a look at these photos. Let me know what you think. My Friend Steve and I were surprised to see how close these cows were to to the back gate of area 51. I have seen other sightings in Indiana and Costa Rica of unidentified objects. We see stuff in Las Vegas as well.
Note: Two UFO enthusiasts were driving down Highway 375 (Extraterrestrial Highway) and decided to take a dirt road to Coyote Summit. They came across two cow carcasses which they thought were mutilated. (See slide show of photos above.) Coyote Summit is near the “back gate” of Area 51. (See gray polygon in above map.) Most of the photos in the above slide show are of one of the cows that shows more signs of possible mutilation. One of the slides shows both cows. It is not clear if these cows were actually mutilated as it is not known how long they have been dead. Certainly predators could have caused some of the damage. It is interesting that the cows were found close to Area 51." Source: http://www.ufosnw.com/newsite/march-...da-930-am-pst/
As mentioned above, it is entirely possible that these animals were 'mutilated' as a result of natural predation, given that fact that the time of death is unknown and the animals may have been exposed for some time. Although, it is worth noting the typical 'jaw strip' type injury.
