Our property, about a mile North of Lake Georgetown, backs up to a flood easement, heavily wooded, runs through the whole neighborhood down to the lake. Kind of a freeway for deer and everything else. About 6:30 Sunday morning, our lab was going fkn nuts in the back yard. Went out on the deck and a doe was barking loudly and repeatedly in the thicket behind our house, probably had a fawn bedded down in the thicket. Doe comes shooting out the left side of the thicket (as we're facing) and charges right back in barking and stomping, and a young mountain lion shoots out the right side, running through a gap in the trees. Liz and I were going DAMN! did we just see that? Gets better. about 20 mins later, Doe starts barking again rushing into the thicket, and the mountain lion flushes again, but this time going through about a 50 yard clearing. No doubt, 100% it was a youn g mountain lion...young because he/she didn't have the bulk of a full grown adult, but dusky color, long tail, running like a cat, short head, short ears about 120 lbs. I've seen several in Black Gap and Big Bend on biology research trips so I know what I was seeing. Sightings in Williamson County are not unprecedented.
