Unconfirmed sighting - just couldn't tell for sure.
End of July 2015, just above (uphill) from Hereford Meadow in the Manastash. Walking back to my truck after scouting for elk. An animal jumped up from a bed 60 yards in front of me. It was definitely canine, grey-colored, round ears, didn't see the tail. It was built like a Saint Bernard, much bigger than any coyote I have every seen. It jumped behind a tree and some bushes, then I saw it take two running strides into the brush. It all happened VERY fast. I looked for tracks but it was matted down grass and didn't see any. I wish I could confirm it, but I didn't get a great look at it.
