Silica formations at the base of the Pohutu Geyser in Te Whakarewarewa Thermal Valley
|
||
|
I have always had a fascination for the forces of nature and, since Rotorua is situated in the largest area of geothermal activity in New Zealand, a chance to see the geysers and boiling mud pools of Te Whakarewarewa Thermal Valley was for me unmissable. |
||
 |
||
|
Pohutu Geyser
|
||
| The largest and most regular geyser in the valley is the Pohutu Geyser. It erupts every hour, shooting boiling water 20m into the air, shrouding the area in clouds of sulphurous steam. | ||

||
| There are a total of over 500 springs in the valley, ranging in temperature from cold to boiling. | ||

Ngararatuatara Cooking Pool
|
||
| The above photo shows one of the violently boiling springs. The Maoris, who have lived in the area for many centuries, used such hot pools for cooking their food. This particular pool got its name from the scale-like silica formations at its edges, which to Maori eyes resembled the skin of the Tuatara (a once common, large primative lizard which is now only found on a few predator-free islands). | ||

Boiling mud pool
|
||
|
Numerous boiling mud pools are dotted around the valley, producing fascinating patterns as they bubble gently away. Some are not so gentle and spurt boiling mud a metre into the air.

Te Whakarewarewa Thermal Valley
|
||
| The area around the Polynesian Baths on the shore of Lake Rotorua is a good spot for viewing some of New Zealands endemic waterbirds, such as the New Zealand Grebe. | ||

Male New Zealand Scaup (Aythya novaeseelandiae)

Female New Zealand Scaup (Aythya novaeseelandiae)
|
||
| The New Zealand Scaup is the most commonly encountered native duck. | ||
 |
||
|
Black Swan (Cygnus atratus)
|
||
| Other species such as the Black Swan and Mallard have been introduced by European settlers. | ||
 |
||
|
Mallard x Pacific Black Duck hybrid
|
||
| Like many other parts of the world where Mallards have been introduced, they have interbred extensively with the less aggressive native species. In this case, the Pacific Black Duck (known as the Grey Duck in New Zealand). Pure-bred Pacific Black Ducks are now only found in more remote areas away from the urban and agricultural areas dominated by the Mallard. | ||

Red-billed Gull (Larus scopulinus)
|
||
| Red-billed Gulls are also easily photographed on the lakeshore. | ||
