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 Trona Pinnacles were formed long ago in a massive lake that once covered this area. The Pinnacles are tufa created by the reaction of spring water released into briny water of the former lake.
This pipe plug is a part of the underground plumbing system of a long extinct Volcano, revealed by erosion, more pipes from the same system are visible in the back. Interestingly, the lava raising up is not mixed thoroughly and composed two distinct types, one dark, the other light. These pipes feed a large volcano, most likely a cone like stratovolcano. The red sandstone of the Comb Ridge monocline stretches across the background.

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!
These are late Cretaceous greywacke sandstones of the Cambria slab. They are interpreted as submarine landslides into a large marine canyon, something like the present-day Monterey Canyon. Ordinarily they look like massive, grey, featureless sandstone. But in flat light & when they are wet, sometimes you get enigmatic hints like this. . .
Field of view is about 2 ft (60 cm) across, by memory.
An dark capture on the edge of the loch near Ardtur with the layers of three mountain ridges in the horizon and some wonderful trees on the shoreline. Fences run all across the bay towards the sandy parts of the Loch Linnhe shore.
This is my latest holiday souvenir that came from the Basque Country. I believe it is called shale and is a sedimentary rock that is formed by layers of mud, clay and bits of minerals that were deposited on top of each other. There were then compressed for millions of years. My geography teacher used to compare rocks to pastries and this one I'd say is like a burned mille-feuille.
Lots of holiday pictures to follow in the next few weeks. HMM everyone!
Rock formations in the lower elevations of Mt. Lemmon, in the Santa Catalina Mountains, near Tucson, Arizona illustrating the geology of the Basin and Range Province. The mountains in this region are known as sky islands (the Madrean Archipelago) and are characterized by their high biodiversity.
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.
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.

The area around Prescott AZ is famous for geological formations known as the granite dells. The most well-known location to see the dells is Lake Watson. We started down this trail that would have taken us there, but quickly realized it was a long, hard walk. So we went back to our car and drove to Prescott, which is a lovely small town. After an excellent lunch we drove to the lake, it did not disappoint.
I processed this image in Photoshop. I used two textures, Lenabem-Anna J’s Texture - Oil paint primer and Flypaper Textures’ Oatmeal.
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.
A land of hoodoos, spires, petrified wood and unique shaped geological features. A place to wander among the stark beauty and find the unusual.
The Swedish west coast was shaped by glaciers, which left behind smooth rock surfaces and large rounded boulders. Geology at its best!
