Death Valley, California, USA
Death Valley National Park is one of many units within the National Park service established because of its underlying geologic theme. Death Valley NP is renowned world-wide for its exposed, complex, unique tectonics and diverse geologic resources. Contained within its boundaries is a diverse rock record stretching throughout most of geologic time. From 1.8 billion-year-old metamorphic rocks exposed in the Black mountains, to recent playa sediments deposited in the valley basins, Death Valley possesses a superb geologic record. Paramount to understanding Death Valley’s geology is realizing that it is an ongoing dynamic process. Wind, water, and plate tectonics are still hard at work shaping the park on a day-to-day basis.
Death Valley is currently building a rock collection of the park’s stratigraphy. The following list of geologic formations and corresponding ages represents what has been collected in the park and are available for viewing at our curatorial facility. 41 formations are listed with a number correlating them to the original reference used to describe and locate them. Based on research, 61 formations are known to exist in the park. Those missing 20 formations have not yet been added to our Stratigraphy Collection. It should be noted that 3 formations have been given unofficial names: Warm Spring Granite, Skidoo Granite, and Strozzi’s Ranch Rhyolite.
Dry Falls-Grant County-Washington State
Dry Falls is a geological wonder of North America. Carved by Ice Age floods more than 13,000 years ago, the former waterfall was once four times the size of Niagara Falls.
Amazing rock formation at Lulworth cove , there is so much erosion at this beautiful location , not sure how long its all going to last :(
I'm always impressed with the varied rich colors of the rocks, boulders and mountains of Glacier Park. Pretty much any color can be found there. According to GNP their striking color comes from the small amount of iron in their composition. Red means oxygen was present when the rock formed, green means the atmosphere was lacking oxygen.
Here's an example taken at Many Glacier.
Thanks for taking a look!
Have a wonderful weekend!
This week's theme for Mosaic Montage Monday was Geological. Sunlight rising on a montage of local geology. HMMM!
The Cottonwood Canyon Road is a rough 47 mile road which travels past many interesting geologic features such as these rounded uplifted sections of rock.
Happy Slider Sunday!

The Trotternish Landslip seen from The Quiraing on the Isle of Skye, with a couple of walkers on the ridge for scale. In geological terms the Trotternish landslip on Skye is recent, occurring around 11,000 to 15,000 years ago and part of it is still moving to this day! Enjoy!
Captured on a new stretch of highway while driving home to Lancaster from our summer at Chautauqua. There was no place to stop so I took a chance, shot blind and used "Sports mode". Seemed to work well. (Car hood is in the lower right).
This photo is my first attempt at mixing RL and SL media. The photo was taken on a geological survey of the southern foothills of the Sierra Nevada Mountain range in southern California during a unusual blizzard about 6-7 years ago. I thought I would be cool to meld two things I love together.

LOL! Nature has its funny side.
This column remains after all the softer sandstone has eroded away from eons of weathering.
The Toadstools, east of Kanab, Utah.
This is a section of rock rising up on the shore of Lake George in Killarney Provincial Park. The colors, textures and shapes combined with the reflection in the water simply mesmerized me. It is a tapestry of history layered and exposed over time by the elements of nature.
Das gesamte Gebiet des Hohwalds um den Valtenberg ist durch Blockfelder geprägt die während der Eiszeit durch Verwitterung des Gesteinsuntergrundes hervorgingen. Es handelt sich um Granodiorit, der in einer, für granitische Gesteine typischen, Wollsackform verwittert. Am Rande des großen Steinbruchs "Valtengrund" blieb die originelle Felsformation zum Glück erhalten, obwohl an ihr bereits Sprenglöcher angelegt worden waren. Den volkstümlichen Namen "Quarkquetsche" verdanken die Felsen ihrer rundlichen Form, "Goldmännchen" hingegen steht wohl auch mit dem in der Umgebung erfolgten Goldbergbau früherer Zeiten in Verbindung.
Granodiorite boulders formed by frost weathering during Saale & Elster glaciation - location: Lusatian Highlands, Saxony, Germany
One of the wonders of this Earth. Totally worth the 14 mile rugged 4x4 trail and the rain, sleet and hail we endured while hiking down.

TBT - dipping into the archives a bit here. This shot was from 2010.
The prominent mountain rising directly behind the dune field at Great Sand Dunes National Park is Mount Herard. It’s part of Colorado’s Sangre de Cristo Range and forms the dramatic alpine backdrop seen from the dunes.
Nebraska. Would love to go back there soon!!
