Rob took me down into the coulees to see the land formations and especially the sandstone. Spectacular hidden treasure.

Our Original Wisconsin Dells Duck tour

Stopped for a couple days in Moab and took a nice stroll through Arches' "Devil's Garden" and "Park Avenue" trails. Yes, this place really exists, and yes, it's cooler than it looks.

 

The cryptobiotic soil formations seem to mirror the larger rock formations.

Good rocks, good clouds, good light, and a lava field. What more could a photographer want?

The initials are not wrong. As guessed by KWG73, this is the Craigwell Brewery. It's one of (I think) three ex-breweries on Calton Road, with another brewery directly opposite.

Sandstone injectite & granite in the Precambrian of Colorado, USA.

 

Seen here is an incredibly rare type of rock. This is a sandstone injectite dike in granite in the Front Range of Colorado.

 

Dikes are planar igneous intrusions that cut across country rocks. (See: www.flickr.com/photos/jsjgeology/albums/72157632467411234) Common lithologies in igneous dikes include granite and basalt/diabase. Some dikes are composed of sedimentary material - such clastic dikes form when material fills in fractures in other rocks. (See: www.flickr.com/photos/jsjgeology/albums/72157711855111128)

 

This dike is composed of lithified sand with granules and pebbles. The surrounding rocks are coarsely-crystalline granites of the Pikes Peak Granite - much of it displays grusolithic weathering. Angular pieces of non-sheared, wall rock granite are in the dike. The dike fill is ~90% quartz sand and ~10% potassium feldspar sand. Mudstone pebbles have been reported from some examples. The clastic dikes in this part of Colorado have been known since the 1890s - gold explorers examined them. For over 100 years, the sandstone dikes have been interpreted as injectites (forcefully injected sand intrusives) - these are some of the largest on Earth. Major and minor sandstone dikes occur - some are over 100 meters across. About 200 dikes have been mapped, plus questionable examples in Boulder County. The dikes are well-cemented and solid in places and crumbly at other sites. Some compound injections are known, representing multiple injection events.

 

The origin of Colorado's sandstone injectite dikes has long been a mystery. The basic idea of overpressured, non-lithified, sandy material being forcefully injected downward into fractured granite is generally accepted, but the timing and the exact source of the material is traditionally undetermined and controversial. Many researchers concluded that the Cambrian-aged Sawatch Sandstone was the source of the sand, because it is the basal Phanerozoic unit atop this area's Precambrian crystalline basement rocks. Did the Sawatch get remobilized during the Laramide Orogeny (= late Mesozoic to early Cenozoic mountain-building event that formed the true Rocky Mountains)? That's a strange idea - it's implausible that a Cambrian sandstone would stay nonlithified for over one-third of a billion years. Some think that injection occurred during the Ancestral Rockies Uplift (Late Paleozoic), or the Sawatch got remobilized in the Early Paleozoic. Regardless of timing, how can a ~5 meter thick Sawatch Sandstone deposit be the source for 100 meter thick sandstone dikes? Maybe the Sawatch was originally thicker, but is now mostly eroded away. Another interpretation is that these are thin and thick fault slices.

 

Detrital zircon analysis of sandstone injectite dikes in central Colorado has shown that the original source of sandy material is a long eroded-away, late Precambrian-aged unit that's been designated the Tava Sandstone.

 

Geologic units: injectite dike (Tava Sandstone, Neoproterozoic, possibly ~680 to 800 Ma) in Pikes Peak Granite (late Mesoproterozoic, 1.08 Ga)

Another shot from the Bastei bridge you can find here.

 

The Bastei is a rocky prominence overlooking the Elbe River within the Elbe Sandstone Mountains in Germany. As a mountain of 305 meters height the Bastei surpasses the river by 194 meters. The landmark was formed by water erosion over one million years ago. Located near Rathen in Saxon Switzerland the Bastei is a landmark in a national park near Pirna southeast of Dresden.

 

The Bastei has been a tourist attraction for over 200 years. In 1824 a wooden bridge was constructed to link several rocks for the visitors. This bridge was replaced in 1851 by the present Bastei Bridge made from sandstone.

 

Die Bastei (305 m ü. NN) ist eine Felsformation mit Aussichtsplattform in der Sächsischen Schweiz auf dem rechten Ufer der Elbe zwischen dem Kurort Rathen und Stadt Wehlen. Sie zählt zu den meistbesuchten Touristenattraktionen der Sächsischen Schweiz. Von der Bastei fällt das schmale Felsriff über 194 m steil zur Elbe ab. Sie bietet eine weite Aussicht ins Elbtal und über das Elbsandsteingebirge.

Sandstone Falls is a ledge waterfall that stretches across the New River in West Virginia. It is the largest waterfall on the New River. This is just a small section of it.

This south side Gate Way path is pocketed with hole's and the one I found some black stuff in is to the right at the top of the tree's.
