Firth of Thames, New Zealand37.1S 175.4E
The Firth of Thames, visible in its entirety upon opening the full version of this orthorectified image, is a large bay located in the north of the North Island of New Zealand.
The firth lies at the southern end of the Hauraki Gulf, southeast of the city of Auckland. It occupies a rift valley or graben between the hilly Coromandel Peninsula (right) and Hunua Ranges which continue into the Hauraki Plains to the south. The large, dark patch below the firth is an area of native forest.
It is the firth of the rivers Waihou and Piako, the former of which was formerly named the Thames River. The Waihou River can be seen running parallel to the mountains on the right and empyting into the bay.
