err.. whats a flat iron? like an iron for ironing clothes?! [

] they're Los Mallos de Riglos near Huesca in north Spain. They're alluvial fan deposits sourced from the Pyrenees - really beautiful and the view from the top is stunning with beautiful eagles and vultures... [

WHat are you seeing That I am not..what are alluvial fan deposits a stretch of land somewhere I have heard of the alluvial fan just recently I saw a picture .. how does that relate to these massive rocks..?

Flat irons are geologic formations where tilted beds are eroded leaving triangular shaped cliffs and steep ridges

Iceberg Ridge, Arizona

In Ichnos' photo, the alluvial fan deposit bedding is close to horizontal- so these are not true "flat-irons" even though they look like several of the classical flat-irons here in the southwest U.S. Alluvial refers to water-deposited, and alluvial fans are most common in dry (desert-like) areas prone to flash floods. In areas of steep relief, these flash floods quickly erode lots of material, which is then deposited when the flood waters reach gentler slopes below- in this case, as Ichnos stated, at the base of the Pyrenes Mountains. Given time, alluvial fans can grow to thousands of feet thick.

Your photo gives me wanderlust once again!

Thanks Bass!! Nice picture also!

Here is a picture from Texas Tech University of the first flat irons I ever say. They are in the Marathon Basin of the Big Bend area of Texas. The picture is of a breached anticline. The white flat irons are formed by the highly erosion resistant Silurian (

? some date it Silurian to Mississippian or Lower Carboniferous) Caballos Novaculite. In the middle of the anticline are the Maravillas Limestone and the Woods Hollow Shale. The weathering has left the more competent Caballos standing while the older Ordovician rocks have been eroded away. They are at 35°-40° and much more spectacular up close.

Novaculite is a highly indurated silicate of probable deep basin origin, although it's considered by a few to be a history of volcanic ash. The radiolarian fossils and algae found in it argue strongly for it having first been a radiolarioan ooze. It is also overlain by a very coarse, progradational deep sea conglomerate, The Tesnus formation. Wonderful place to do field work.

correct again-
The rock here is columnar basalt (volcanic)- when the lava flow is thick enough to allow slow cooling, shrinking during cooling forms columns with the hexagonal shapes shown.

This peak is in a World Heritage Area and a National Park.
Top of the mountain is 1545 meters.
Lower slopes are in mixed deciduous/conifer rainforest.
You may have a devil of a time figuring this one.

If it is a temperate rainforest, then it's most likely to be in the Pacific North-West of North America. "a devil of a time" huh? Is there a place called Satans Lake / Hells Hill.....?

Durdle door... []

To easy for you

The natural arch of Durdle Door has been cut by the sea through the almost vertical Purbeck Caps and the top of the Portland Freestone. From the landward side, as seen here, the Portland Stone is hardly visible and the surfaces which you see here are mainly those of the Purbeck stromatolitic limestones (the Soft Cap), like those of the Fossil Forest. Holes left by late Jurassic trees are visible. The soft Wealden strata, thin here partly because of strike faulting, have been eroded away on this side except for a narrow connecting peninsula protected to some extent by the wall of stone. Originally there was Kimmeridge Clay seaward of Durdle Door but these relatively soft strata have been easily removed by the sea.

Wrong continent- in fact, wrong hemisphere. For us "right-side-uppers", we'd have to quaff our beer "upside-down" while viewing this peak.

Sorry bass it seems i jumped in with my picture before yours had been answered. [:I]i shall disqualify myself from this one as punishment.

Of course i know the answer to your one, its so easy a baby rocking in a cradle could give you the answer. [
