I have no idea what you mean by viewable map. Do you mean online or a paper map? I used to live in Corbin and the local tackle stores have some paper maps you can buy.
But if your looking for an online topo map you can get it at this link.

Go to Vox file and Sawyer cells and download the ones called TIFF. You can get online topo maps for free of anywhere in Kentucky on this link. You could print them if you want.
