Can any plane spotters advise if these are anything unusual? They seemed noisier than the usual modern light aircraft, but dont have the pointy wings of spitfires.

Hierve Al Agua
Hierve el Agua (Spanish for "the water boils") is set of natural rock formations in the Mexican state of Oaxaca that resemble cascades of water. The site is located about 70 km east of Oaxaca city, past Mitla, in the municipality of San Lorenzo Albarradas, with a narrow, winding unpaved road leading to the site. The site consists of two rock shelves or cliffs which rise between fifty and ninety metres from the valley below, from which extend nearly white rock formations which look like waterfalls. These formations are created by fresh water springs, whose water is over-saturated with calcium carbonate and other minerals. As the water scurries over the cliffs, the excess minerals are deposited, much in the same manner that stalactites are formed in caves. One of the cliffs, called the "cascada chica" (small waterfall) or the Amphitheatre, contains two large artificial pools for swimming as well as a number of small natural pools. One of the artificial pools is very near the edge of the cliff.
Magnetite-rich ion-formation in the Precambrian of Ontario, Canada.
This is a cross-section exposure of Archean-aged banded iron formation (BIF). I'm not absolutely sure about the formal stratigraphic name of the unit at this site, but it appears to be the Michipicoten Iron-Formation (Neoarchean, 2.696 to 2.749 billion years old).
The round object is a magnet sticking to the outcrop. The black material in the rocks is magnetite (Iron oxide, Fe3O4).
Locality: Route 17 roadcut, just west of Antoine Lake, southeast of Bridget Lake, south-southwest of the town of Wawa, Michipicoten Greenstone Belt, Ontario, southeastern Canada (47° 53’ 44.36” North latitude, 84° 50’ 47.95” West longitude)

this anticline formation is directly opposite the Cova dels Adells- the ravine in between was washed out by erosion (water).

A portion of the St. Louis River flowing over rocks of the Thomson Formation.
The Thomson Formation consists of slate (23%-31%), siltstone (35%-43%) and graywacke (34%). (Percentages are from two measured sections and reported in 1970.) Most beds of the formation are less than one foot thick; and geologists believe the individual graywacke and siltstone beds represent individual sedimentary units.
The formation extends through northern Carlton and western St. Louis Counties, and westward as far as southeastern Otter Tail, northern Wadena and Southern Todd Counties. (Although these western locations are cut off by other formations.) the type location (where it was first identified) is along the St. Louis River at Thomson, Minnesota. The sediments formed in the Animikie Basin, which roughly follows western Lake Superior, although it extended west into central Minnesota. The Penokean Orogeny folded and metamorphosed the sediments about 1,700 million years ago.
