Is it the Great Wall of China? I don’t think so!
Is it the fences of the Cotswolds in England? I don’t think so!
This rock wall intrigued me on our drive through the Texas Hill Country. We enjoyed wind on our faces in my husband Lynn’s Mazda Miata convertible. Lynn has walked part of the Great Wall of China that was built over centuries. Stone or soil mixed with gravel and pressed between two boards to dry created the wall. It separated countries, enemies, and trade routes.
I’ve visited the Cotswolds of England and found their honey-colored stone fences stacked without any sort of cement fascinating. Both countries built walls and fences out of rocks that surfaced from the soil. Both countries used naturally available materials. Their walls, fences, structures separated countries, property and livestock.
This rock fence on our ride was about 2 feet wide, 3-4 feet tall, and a mile or more long. I suspect it merely divided the property from the road as any typical fence would. It was one of a kind to my eye.
A DIFFERENT KIND OF FENCE
We smelled the wafting scent of cedar trees being burned from landscapes overrun by cedar trees because of a recent 3-6 inch rain that broke a drought somewhat and lifted burn bans. Historically cedar trees were crafted into roof shingles in this area. No longer used in shingles, the tree can still be stripped and set as fence posts side-by-side here or with barbed wire. 
An invasive species, cedar trees slurp up too much water from our soil and aquifer, leaving the area drier than ever and so must be cut from ranch land and burned. A burden, cost, and nuisance to land owners.
BIRDS AND ANIMALS
The thrill of the day however was spotting a roadrunner fly to a low-hung tree branch and roost there AND then spying two zebras close to the fence line next to the road on an exotic animal hunting ranch. Neither of which I could capture in a photo.
ROCK
Our destination was Enchanted Rock, located 21 miles north of Fredericksburg, a German community and shopping haven, and 26 miles south of Llano, Texas, the deer capital of the state. A granite rock erupts in the ground with little to no vegetation. The State park allows for picnicking, climbing, geocaching, nature studies, birding, and stargazing. Be sure to bring your protein snacks and plenty of water. Wear athletic shoes or hiking boots for climbing. A climb can be achieved in half a day. Beware of rattlesnakes!
When you drive TX-16 S and Ranch Rd 965 you understand why it is called the Texas Hill Country. Broad panoramas, rock walls, and lush green hills welcome you to the Texas Hill Country.
