Hiking in the Mogollon Rim area of northern Arizona...when I get south of 34 deg, 30', 0" the GPS screen becomes void of all contour lines and other data and I get a message on the screen: "no map data". I can still set waypoints and follow a breadcrumb trail, but no map features are available.
Why is this?
I did notice on a standard paper topo map that the contour lines change interval levels at this point.
