The Wellington Fault in the Totara Park area of Upper Hutt.
The fault runs along the central reservation of the road in the background, and then through this reserve. Movement of the fault over time means that the land on right (NW) side is higher than that on the left (SE), forming this "scarplet".
At the Bridge between Continents which spans this fault between the Eurasian and North American tectonic plates.

While walking along the beach, I discovered a prominent fault exposed in the rocks along the buff. The sedimentary layers are offset with the thin-bedded grey shales on the left side dropping down in relation to the thick-bedded orange sandstone on the right side.
The Hayward Fault Exposed at Central Park, Fremont, California. Commemorate the 1906 San Francisco earthquake by standing face-to-face with an earthquake fault!
Did about an hour geology review with Bruce of places we have been together in the Grand canyon

Folded-faulted magnetite-quartz banded iron formation in the Precambrian of Ontario, Canada.
Whitish = quartz-rich
Dark gray = magnetite-rich
The outcrop seen here consists of BIFs - banded iron formations. BIFs are unusual, dense sedimentary rocks consisting of alternating layers of iron-rich oxides and iron-rich silicates. Most BIFs are Proterozoic in age (although some are Late Archean), and do not form today - they're “extinct”! Many specific varieties of iron formation are known, and some are given special rock names. For example, jaspilite is an attractive reddish & silvery gray banded rock consisting of hematite, red chert (“jasper”), and specular hematite or magnetite. This outcrop has magnetite-quartz BIF.
Because of their age, most BIFs have been around long enough to have been subjected to one or more orogenic (mountain-building) events. As such, most BIFs are folded, faulted, and/or metamorphosed to varying degrees.
BIFs are known from around the world, but some of the most famous & extensive BIF deposits are found in the vicinity of North America’s Lake Superior Basin. Many BIFs have economic concentrations of iron and are mined. BIFs are the most important variety of iron ore on Earth.
The rocks at this locality have small-scale folds and faults. Published literature refers to the folding here as soft-sediment deformation.
The outcrop surface here was glacially eroded and smoothed during the Pleistocene Ice Age.
Stratigraphy: Temagami Iron-Formation, lower Neoarchean, ~2.736 Ga
Locality: Temagami North Outcrop - roadcut on the eastern side of Route 11, immediately north of town of Temagami, eastern Ontario, southeastern Canada (47° 04’ 08.32” North latitude, 79° 47’ 25.34” West longitude)
The canyon east of Mecca, north of the Salton Sea, on the way to Joshua Tree is right over the fault and has some wild, tortured features.
Not some bizarre arty moment on my part but a genuine creation of the serious camera-card fault I experienced after my first day. Though I managed to retrieve most shots through an online service at home later many were either lost altogether or mangled up with elements of earlier pics and thus survived only as strange abstract fragments!
The Cathedrale St Etienne in Metz is one of the most impressive gothic cathedrals in France and also distinguished by being one of the tallest. It dates mainly from the 13th century but has been added to much since.
Externally it is the bulk of the building and the sheer height of it's clerestorey windows (so much of the building appears to be glass) that impresses most. The two towers are relatively small (and oddly positioned part way down the nave instead of the normal facade arrangement) but they are most graceful structures (the northern one only completed in the 19th century). The portals are rich with sculpture but are almost entirely 19th century work (the west porch being the largest, but normal entrance is by a secondary and no less richly adorned portal at the south west corner of the nave).
Inside the height of the vaults is breathtaking, the narrowness of the interior accentuating the effect. The arcades are somewhat low in proportion to the enormous areas of clerestorey glazing that appears to take up at least half of the wall space. The south side is enlivened by two projecting chapels with apses accessed from the aisle.
The outstanding feature of the cathedral is it's stained glass, most of it late medieval including great swathes of early 16th century work by Valentin Bousch. More famous still however are the more recent 20th century contributions to the glazing (following the loss of some 19th century glass in World War II) including three rich windows by Marc Chagall and a set of semi abstract pieces by Jacques Villon.
