I was driving back from my monthly breakfast with 'the guys' (we went to a Fifties restaurant and got chaufered on our way in an old Sixties car!), and I passed this beautiful old stone fence. It was sunny and bright, so this time I stopped for pictures.
This is the only stone fence I've seen built as a dry stone wall out of these flat pieces of dolostone. It's from the Manitoulin Formation, which I've featured before in pictures of several waterfalls - thin flat layers of rock. We have hundreds of old stone fencerows where all manner of boulders have been piled in lines, but I've never seen a dry stone wall like this one!
There's obviously an outcrop of this formation on this farm, and perhaps scattered rocks in the fields all similarly thin. The dry stone fence stretches all the way across the front of the 100 acre farm, from one side to the other.
The construction is amazing, obviously built by a talented stonemason decades ago. It may even be over 100 years old. All the rocks have to be placed slanting in slightly, letting rain run
away, to avoid frost damage. With proper construction, such a dry stone
wall will last much longer than one where the rocks are mortared
You can see how there are larger flat dolostone slabs on top to help shed the rain. And looking over the fence you catch part of the farmhouse and some interesting trees to the left.
This view, beside the driveway, provides good evidence that a stone fence like this needs regular maintenance! And there's the patch of whitish looking trees in the distance again.
A closer look reveals that they are mature locust trees, sometimes planted around farmsteads 100+ years ago. And they were in bloom when I took this picture, with luxurious white blooms. Sorry I don't have a close-up. I only know of three old farmsteads in the whole Beaver Valley region with old locust trees like these.
