Volcanic Sulphur Mounds
These are Sub-aqueous sulphur mounds found at Waiotapu, New Zealand
As you walk along the 3 km walking track that covers the attractions in Wai-O-Tapu, south of Rotorua, you are visually treated to all many different colours, sights and smells and it a really is very interesting place to visit.
I really enjoyed this place. We spent hours there – it was such fun with my 2 granddaughters and their mother. We all took photos and had such fun together.
These yellow mounds are where sulphur has accumulated over the years, are found in Sulphur Mound Valley, in the western part of Echo Lake.
That lake was drained in the 1950’s to make a road, and these giant mounds of sulphur were exposed on the lake bed. The yellow mounds are up to 2 metres high and contain sulphur and a little silica.
How were they formed?
Molten sulphur was formed underground and it was pushed upwards on the lake floor by gas.
The molten sulphur cools as it touches the cooler lake water, and then it changes from liquid to solid, with the gases trapped in the solidifying sulphur.
These trapped gases show up on the outer surface of the mounds. |

Your image has some very nice tonal colors all the Persian. I sort of like that way you what your font found in the lower left hand corner. It gives a good explanation of the picture. When they used geologic structures are very interesting. I am sure that came with love seeing these also. . Thank you so much for posting this image. I hope you enjoy your fall. Bob

Hi Janice,
very strange place, thanks for the note so we can understand it.
I like this compo: good POV and lovely soft colours.
The only thing that distracts my eye a little are the small branches from the right... but they are quite small.
TFS
regards,
Brenda
