Thank you!
I had another orthographic camera positioned above the island that displayed to a render texture, which I used as the image for a canvas raw image component.
The camera culling was set to only see the terrain layer and a mini-map layer. I did the player icon by placing a sprite above the players head, and assigning it to the mini-map layer.
The reason the map is red is because I forgot I had the fog turned on, decided it looked cool, and kept it.
