I am looking for a map site that I can look at a satellite image and overlay the topo grids. The area I will be hunting seems to have the south facing slope sage and open while the north facing slopes are trees. I look at the topo map and find a place that looks promising and when I toggle to the satellite it is open sage. I thought of printing a caltopo map and shading in the timbered areas. Maybe someone knows of a site that has the option I am looking for.
