My home county in Florida is Walton County. It has a place near the Alabama line which is 345 feet. That is the highest point in Florida not counting buildings, towers etc.
It is surprisingly hilly in the area and in fact there are places near me also in Walton, county which are also very rolling.
Far more contour than the Kansas Plains which are far higher elevation wise.
Isn’t the point you refer to called Britton Hill?
