It isn't easy to show how big this track is but it is about 6 inches across. One of the benefits of a fresh snow last night is what you can find in the way of tracks. This big cat crossed about 110 yards from the house where there were also deer tracks. When I first saw them I estimated that they had been made within the last two or three hours because the deer tracks already had snow in them and I saw the deer earlier this morning. Based on the depth and size of the tracks the mountain lion probably ran 150-160 lbs. Earlier today the dogs had their noses in the air so this is what they were alerted to. No wonder they wanted to come back inside so fast.
