ENTS,
 
Here is the biggest Shortleaf Pine that I've seen. It's within a few hundred yards of the Loblolly Pine I showed you tonight.
As you can see in the photo, it splits into muliple leaders, about 10 feet above the ground. Below that point it's pefectly straight, and definitely one trunk. I didn't take any close-up pictures of this tree. The CBH is 6'9", the same as the Loblolly Pine.
To me the mature Shortleaf Pines appear identical to Pitch Pines of the same age and size. But I've been told that the dead giveaway is the tiny cones. I was wondering if there is simply a lot of variation in cone size, but apparently not as much as that. Anyway, here's the biggie. The entrance to the dirt road where this tree and the big Loblolly Pine are, is only 3.6 miles from here, so very easy to get to.
