What geographic feature is this?

Question by razorbladevalentine: What geographic feature is this?

I’m looking at Google Earth. Kentucky. I’m looking at this large long gap running along the Virginia part of the state. It runs between state highway 3403 (119) and state highway 931 (160). Can anyone tell me what kind of geological feature this is? What’s it called? Does it have a name or story about how it was formed?

took me a minute to find it, but it is called a syncline, it is a downward pointing fold in sedimentary rock

it is a region in the Appalachians called the valley and ridge province whee the rock is folded into parallel synclines and anticlines (upward pointing folds)
