Panorama. 2 shots stitched together for this one. These are hydrothermal hot springs which come in different colours around the borders ( See Grand Prismatic on Internet). I believe the colours are from microbe like creatures that can survive in these extremely hot waters but different microbes of different colours, at different temperatures , giving these wonderful rings in the pools. Thanks to all for votes on bear etc.
