That is the Grand Prismatic Spring in Yellowstone National Park, USA.
According to Wikipedia:
The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world.The vivid colors in the spring are the result of pigmented bacteria in the microbial mats that grow around the edges of the mineral-rich water. The bacteria produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature of the water which favors one bacterium over another. In the summer, the mats tend to be orange and red, whereas in the winter the mats are usually dark green. The center of the pool is sterile due to extreme heat.The deep blue color of the water in the center of the pool results from the intrinsic blue color of water, itself the result of water’s selective absorption of red wavelengths of visible light. Though this effect is responsible for making all large bodies of water blue, it is particularly intense in Grand Prismatic Spring because of the high purity and depth of the water in the middle of the spring.The spring is approximately 250 by 300 feet (80 by 90 m) in size and is 160 feet (50 m) deep. The spring discharges an estimated 560 US gallons (2,100 L) of 160 F (70 C) water per minute.

The Queensland Bottle Tree — Brachychiton Rupestris originally classified in the family Sterculiaceae, which is now within Malvaceae, is native of Queensland, Australia. Its grossly swollen trunk gives it a remarkable appearance and gives rise to the name. As a succulent, drought-deciduous tree, it is tolerant of a range of various soils, and temperatures.
It can grow to 18–20 meters (59–65 feet) in height and its trunk has the unique shape of a bottle. Its swollen trunk is primarily used for water storage. On every tree the leaves are variable from narrow and elliptic to deeply divided. Clusters of yellowy bell shaped flowers are hidden within the foliage, and are followed by woody boat-shaped fruits.
