But you still have a horizon, right??   Remember, the distance to the horizon is roughly 8/7 times the square root of height of eye.   So for someone standing on the flats themselves, the distance to the horizon would be less than three miles.  Sure, you can see mountains in the distance, but their base is hidden by the curvature of the earth.   This is similar to, for example, taking shots on a large lake or bay where there is shore in the distance but beyond the natural horizon.

I read that to be an elevation change of (at most) 16 feet over 10 miles, which works out to just over 1 arc minute. This spot would work nicely.

Perhaps in selected directions. However, much of the horizon is dotted with distant mountains.
