Taken along the summit rim trail of Mount Vesuvius. Looking at a portion of the interior of the Gran Cono crater.
When I was a child, my father spent hours, with Chicago Motor Club maps spread out before him, planning a family trip to the Pacific Northwest and the Cascade Range. In his own childhood he'd been to Crater Lake in Oregon and for good reason thought it the most beautiful place on Earth.
While in my early years we did get to many splendid places in the West, including the Yellowstone Caldera and the Canadian Rockies, we never quite made it all the way to the Cascade peaks that form the magnificent (and dangerous) continental volcanic arc a little inboard from the subducting Juan de Fuca Plate. As a matter of fact, I didn't get to them by myself until my middle adulthood, long after I'd been to the tops of Vesuvius, Etna, and Stromboli.
Of that Italian triad, Vesuvius was my first ascent. And it was the first place I'd ever visited that seemed to be chronologically unhitched from the landscape below and around it.
Whether they're currently erupting or not, the world's great volcanic summits invest one with the feeling that the planet itself is still very young and forming. It's an eerie thing to suddenly find oneself in an early chapter of the Earth's creation—the Hadean, perhaps, or the dawn of the Eoarchean, some 4 Ga before the birth of our species.
That makes it all the more ironic that the geology here is actually remarkably young. This fact is made abundantly clear in one of my main sources for this series, "Volcanic Evolution of the Somma-Vesuvius Complex (Italy)," Sbrana et al., Journal of Maps, January 2020.
If I'm interpreting one of that article's illustrations correctly, the upper portion of the crater wall shown in the photo above was almost all produced in the 1944 eruption, during the Allies' torturous advance up the Italian peninsula. Only the lowest quarter of the visible strata are older; and they just date to the period 1913-1930.
Incidentally, notice that I used the term strata for rock units that are obviously igneous. If you're someone who's taken a single geology course, perhaps as a 100-level science elective in college, you probably think that strata (synonymous with layers and beds) are the sole intellectual property of sedimentary rocks.
So it appears I'm violating a basic understanding uttered by countless Earth-science instructors. But it turns out that what they told you is something I call a beginner's truth—an educatively helpful fact that is partly abrogated as one gains additional experience.
It's true that a nice set of stacked beds is an excellent way to identify sedimentary rocks. But in composite volcanoes like Vesuvius, also known as stratovolcanoes for good reason, you'll see striking patterns of alternating layers, too. In this case, though, they're not made of sandstone, limestone, or some other clastic or chemically precipitated type. Instead, they're a succession of tephra (ash, lapilli, pumice, and other ejected particles) and lava flows that poured onto the surface while still in a liquid state.
In Part 1 of this set, I discussed the petrology and predominant rock types of Vesuvius' more recently erupted material. But in this post, instead of focusing on the arcanities of tephrite, phonolite, and their intergradations, let's just identify what beds are lava and which are the tephra.
Fortunately, this is one of the best places in the world to see the inner structure of a stratovolcano: the crater is about 500 m (1,640 ft) wide and 300 m (984 ft) deep. And its almost-vertical walls are nothing less than the opened pages of a geology textbook.
First of all, the sunlit, reddish-brown material blanketing the rim is mostly tephra. When you actually walk on it, it has a crunchy, granular to dusty texture.
Farther down the wall, in the shade, the tephra takes on a darker aspect. In contrast, the lava strata are lighter-toned and more massive (thicker). See how many different layers you can actually count. Each bed represents its own geologic story worthy of remembrance.

Taken along the footpath to Vesuvius' Gran Cono summit. Facing south-southeastward.
Ah, that Mediterranean haze. It's the product of the local atmosphere's high aerosol (suspended particle) count. That in turn can be due to various factors, including the automotive and urban pollution no doubt present this close to the Neapolitan megalopolis. But the main cause reportedly is dust blown northward from the Sahara Desert. The grand result of all these tiny floating bits of matter is the region's milky, misty, opalescent air.
In the left foreground we see a small stretch of the volcano's relatively steep western flank. On the Gran Cono, rocks and pumice shards generally have an angle of repose of about 30 degrees from horizontal. According to my own highly sophisticated measurement technology—a plastic protractor pressed against my PC screen—the lower slope is almost exactly that, with the upper portion being up to 40 degrees or so.
Far far beyond that crunchy, crumbly surface lies the city of Castellammare di Stabia, facing the Gulf of Naples. The Pompeii archaeological complex is also partially visible, I think, at far left behind the upper section of the slope.
The high ground on the horizon is the eastern side of the Sorrento Peninsula. It's composed of Mesozoic-era limestones with some Quaternary pyroclastic deposits wafted in from you-know-where.
Speaking of slopes, if you've ever driven around the Sorrento area, you know how vertiginous its peninsula's hillsides are in many places. With all those hairpin turns and tight bends around projecting masses of rock, it's not a good place for drivers to take their eyes off the road.

PSD is the flight integration facility where pressure suits survival kits, parachutes and other flight equipment are maintained, fitted, overhauled or integrated into the aircraft systems. (At this time U2R/TR-1, and SR-71A)
This is a David Clark S1031 suit, a seven layered suit used to unlimited altitude. The suit uses 100% oxygen which enters the suit through a pressure regulator in the rear of the helmet. The helmet has a face curtain to assure that any suit leaks do not decompress the face area, and that pressure is available for breathing. Exhaled gases get passed through the face curtain to the suit environment. The suit pressure is maintained with compressed Oxygen from the aircraft system, through a dual stage suit pressure controller. The regulator is operated by two vacuum aneroids which compress seals, if the ambient cabin pressure is less than required, the vacuum aneroids contract allowing system pressure to enter the suit. The small pulley with the steel cable running through it is the helmet hold-down strap which stops the helmet from rising when the suit is inflated.
In the event of ejection there are 2 auxiliary oxygen bottles in the survival kit which should supply enough oxygen for the crewman to reach the ground.
Integrated into the suit is the parachute harness, connected by the Koch connector on her left shoulder. The parachute is a 35 foot diameter chute ballistically opened by a mortar fired 25 pound steel slug. The chute utilizes a quarter deployment bag, only partially opening at altitude. Once speed has reduced, the chute fully deploys.
The suit also contains automatic life preservers under each arm, equipped with a salt water sensor which immediately inflates the preservers when exposed to sea-water.
There have been successful ejections above 80,000 feet.

For those of you that don't know, I co-wrote a book this year with Programmer Andrew Morton. The book is about using the Flickr API and PHP together, to help build customized websites, and manage your Flickr photos. The book has something for everyone, and is written to be accessible and useful to both novice web designers and advanced programmers.
If you are interested in web programming, the book is on the shelves now! If want to save some trees, you can get the book as an ebook directly from the publisher, Apress.
If you are interested in reviewing the book, let me know. Limited availablity!
Finally, if you dig this book, you should digg it
Video of three black and white collages created in 2003...these pieces have never been exhibited and by using iMovie they now have a way of finding an audience
The narration with the video was also written back in 2003 when the pieces were first created...l found by writing a narration to all my pieces back in those days helped me with inner and outer consolidation and this allowed many other awarenesses to slowly become clear...
I have only just realised these videos are also becoming my artistic retrospective...
