Here's a very good elevation map of the mountains in my region: https://wmblogs.wm.edu/wp-content/uploads/2016/09/RainFig5.jpg
AM - Allegheny Mountains (extends north of this map, covering about five states in total)
SV - Shenandoah Valley
MR - Mount Rogers
BRM - Blue Ridge Mountains
The map shows well why it's called 'Highlands'. Compare the large red area to the lower green and grey denoted areas. I enjoy studying maps like this. They pique curiosity and inspire exploration.
If the above link does not work try this: https://wmblogs.wm.edu/cmbail/let-it-rain/ and scroll down to the fourth map and click it.
Have a great weekend!
