The missing names of rivers and mountains on Google Maps

Google Maps has the names of the most obscure lanes and alleys, but the names are missing once you leave land and try to get wet.

They do seem to have the names of the biggest lakes and man-made reservoirs, but the names of most rivers and other natural features are simply missing.

Even New York City: try to find the names of the Hudson, the Harlem River, or the East River - hard to find.

Perhaps this is a temporary blip, and that Google is working on creating an overlay of nomenclature from topographic maps. I hope so.

Or else, as Google Maps becomes the most common map reference, we'll be losing important knowledge about the land.
