This waterfall is much harder to photograph than Lower Proxy Falls nearby. For one thing, a big pool of water at the base of this thing makes it difficult to get right in front of it. I was standing in the creek to take this shot.

A short way down from Lower Panorama point the view opens remind you of the altitude.
Lizard ridge, also known as Glucose ridge offers access to Main Range but is a long and difficult route.

--The American Folk Art Museum is an art museum in the Upper West Side of Manhattan in New York City, at 2 Lincoln Square, Columbus Avenue at 66th Street. -Wikipedia
Very small space for the museum now, they can only show a small amount of their amazing collection at a time.

Taken from the West trail to Pitchoff Mt. The early fall colors can be seen against the background of upper Cascade Lake.
In the dark of a December night the welcome sign to the Upper Village Market welcomes you to the light of groceries and coffee in Whistler, BC.
Upper Purgatory Falls in Mont Vernon. With a mix of dense forest cover and filtered sunlight, there were difficult lighting conditions. I did a fair amount of post-processing in Lightroom 4, but am happy with the result.
One of the upper pools at Iva Bell Hotsprings. The view is great, the water is hot. Totally worth the hike. There is some muck in the pools, get over it. It's just dirt and stuff, probably good for your skin or something. ;-)
Ebor Falls are located on the Guy Fawkes River near Ebor and about 37 kilometres north-east of Wollomombi on Waterfall Way in the New England region of New South Wales, Australia.
The first lookout is on a sealed road, approximately 200 metres off the Waterfall Way. This viewing platform shows the upper falls tumbling 115 metres over columned basalt rock in two falls. The lower Ebor falls, 600 metres further on, fall into a steep forested gorge below.
Largest waterfall in Indiana (combined hight and volume, and taking into account upper and lower falls)
Spinifex metakomatiite (serpentinized) in the Precambrian of Ontario, Canada. (this outcrop is bleached to prevent growth of vegetation; this is a NO HAMMER locality)
Komatiites are very rare, magnesium-rich, extrusive, ultramafic igneous rocks. They are named after the Komati River Valley in South Africa, the type locality. Komatiite is an exceedingly rare type of lava. No volcano on Earth erupts this material today. Komatiites are essentially restricted to the Archean (4.55 to 2.5 billion years ago). Experimental evidence has shown that komatiite lavas, when originally erupted, were considerably hotter (~1600º C) than any modern lava type on Earth. This indicates that Earth’s mantle was much hotter than now. Other geologic evidence also indicates that early Earth’s heat flux was much higher than today’s.
Komatiite lava had a very low viscosity - it could flow like an ultradense gas. This property permitted the solidification of some individual lava flows that are only 1 cm thick.
The classic texture of komatiites is spinifex texture, named after clumps of long, spiky (& painful!) grasses. Komatiites with spinifex texture have short to long blades or plates of olivine mixed with smaller-scale blades of pyroxene.
All Archean komatiites are metamorphosed - the original igneous mineralogy (olivine, pyroxene, minor chromite, etc.) is gone to mostly gone. Such rocks are best termed metakomatiites, but the prefix “meta-” is usually not specified in writing.
Komatiites have economic significance, as many are closely associated with copper-nickel minerals (chalcopyrite & pentlandite), plus minor platinum-group elements, arsenides, bismuthides, and maybe a little gold and silver. Komatiites are a world-class source of nickel in Canada and Western Australia.
The outcrop seen here is part of a stack of tectonically-tilted, nearly vertical, komatiite lava flows at Pyke Hill, Ontario, Canada. The original olivine spinifex texture is serpentinized for the most part. Pyroxene spinifex consists of small, felted needles. Cumulate-textured units are also present in these lava flows, plus knobby peridotite units and brecciated or cooling-cracked flow tops.
Pyke Hill is a world-famous locality for komatiites. The rocks there are part of the Kidd-Munro Assemblage, which consists of ultramafic and mafic volcanic rocks intruded by mafic to ultramafic dikes and sill-like bodies. Minor felsic volcanic rocks are also present. Volcanogenic massive sulfide deposits occur in the Kidd-Munro Assemblage - they have been mined at the Texas Gulf Mine and the Potter Mine.
The peridotites at Pyke Hill are 37 to 45% silica. Spinifex-textured rocks here are 42 to 45% silica. The chromium (Cr) content ranges from 1500 to 5000 parts per million in the peridotite and spinifex-textured rocks. Nickel (Ni) content ranges from 400 to 2000 parts per million.
