@Stephanie Hoeflin ,
Maybe you have seen/used ABRP (A Better Route Planner)
https://abetterrouteplanner.com/ .
It shows chargers, and route elevations for planning trips. I used it for a trip from Detroit to Charlotte, so I could plan where best to charge relative to the mountains.
In the attached images, disregard the info related to my vehicle (has the 62kWh). More relevant are the differences in elevations depending on the selected route. (I put Cleveland, TN in just as a random-ish start location, based on your description. )
I also use PlugShare.com... both planners have mobile apps, but the ABRP has the nice elevation widget.
