Fossil wood in the Jurassic of Utah, USA.
This fossil tree trunk is in the Morrison Formation, an Upper Jurassic succession that is widely distributed in many western American states. The Morrison consists of fluvial (river/floodplain) and lacustrine (lake) deposits, plus reddish-colored paleosol horizons. Dinosaur bones and dinosaur tracks are moderately common in Morrison Formation sediments. Exceptionally dinosaur-rich localities include Como Bluff in Wyoming, Dinosaur National Monument in Utah, Dinosaur Ridge in Colorado, and the Cleveland-Lloyd Quarry in Utah.
This type of fossil wood is usually referred to as "petrified wood". It's a preservation style actually called "permineralization" - the small-scale porosity of buried wood or bone gets filled with minerals as groundwater percolates through. The most common permineralization mineral is quartz (SiO2). Cellular-level details can be preserved in permineralized wood, but some examples have little original botanical structure remaining.

Surface formations are made from deposits as they come out of solution when water from the mud pool, below the viewing platform, drain towards my position for this shot. See my next upload for a view of the boiling pool.
Namafjall is a high-temperature geothermal area. At a depth of 100m the temperature is 200 degrees C. Steam issue from the surface of the earth via vents through boiling mud pools. The hot springs produce considerable sulphur deposits. Along with fumaroie gases such as hydrogen sulphide these are responsible for the characteristic smell in the area. In previous centuries the sulphur was mined in Iceland to be used in gunpowder production.

These cranes hover in the air before landing. Their form was perfect!
All along the un-named stream (I have been informed that the streams name is Seehan Creek), there are all kinds of limestone rock formations to be seen. Over the years the water in the stream has chewed away at these rocks.
