Agates Agate is a microcrystalline variety of silica, chiefly Chalcedony, characterised by its fineness of grain and brightness of color. Although Agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks
These people were in Pompeii when Mount Vesuvius erupted. The eruption released tons of pumice, a light volcanic rock. It completely buried the town and the people. Under the pumice, the bodies were preserved. -- Taran Kalle

Mount Elgon August 9, 1984 Description: Clouds encircle the lofty rim of Africa's Mount Elgon, a huge, long-extinct volcano on the border between Uganda and Kenya. The solitary volcano has one of the world's largest intact calderas, a cauldron-like central depression. The caldera is about 6.5 kilometers (4 miles) across and formed following an eruption, when the emptied magma chamber collapsed under the weight of volcanic rock above it.
litlanesfoss waterfall in Iceland - "The remarkably regular six-sided columns of volcanic rock, called pillar basalt, were created when lava cooled down over a long period of time." And looks like Krypton.
Egypt not only has a "White Desert", which I posted, but also a "Black Desert". This black desert seems to be made of piles of shiny volcanic rock.
Richat Structure, Mauritania, 2001The 31-mile-wide bull's-eye in the western Sahara is a landmark for astronauts. The structure formed when a volcanic dome hardened and gradually eroded, exposing the onion-like layers of rock. Desert sands appear white and pale yellow at the corners; less sandy, rocky areas are green; and volcanic rocks are blue.
Known as Waiahuakua, this is the second longest sea cave in the world, stretching 1,155ft. It is known as the Sacred Water Cave and as the Double Door cave – as it has both an entrance and an exit. Kayak tours run through the cave to allow visitors a close-up view of the caverns huge length. A fissure in the roof of the volcanic rock allows water to gush into the amazing cavern.
Devil's Tower, WY. Cheyenne was too far out of the way but this is much more interesting. Devil's Tower is an intrusion of volcanic rock that cooled into 6-sided columns, probably surrounded originally by softer sedimentary rock that eroded away leaving the Tower. I walked all the way around it and have views from all sides and also across the plain below. Wonderful experience (I'm a big "Close Encounters" fan).
Cave Hotels. Turkey. The legendary cave hotels in the Turkish region of Cappadocia are one of the most extraordinary hotel complexes on the globe. The suits have been carved out of soft volcanic rocks that cover the entire region. In the past, the rock shelters were used as houses, churches and monasteries.
A search for diamonds in Canada's far north turned up a rare fossil — a chunk of a redwood sealed in volcanic rock more than 50 million years ago.
Veidivötn is a watery landscape in central Iceland on the northwest edge of the Vatnajoküll Glacier, flown through by many meltwater streams. It contains some 50 lakes, many of them in craters caused by Veidivötn’s position above a volcanic fissure zone
