Bryce Canyon National Park is a park located in southweastern Utah in the United States.
The major feature of the park is Bryce Canyon, which despite its name, is not a canyon, but a collection of giant natural amphitheaters along the eastern side of the Paunsaugunt Plateau.
Bryce is distinctive due to geological structures called hoodoos, formed by frost weathering and stream erosion of the river and lake bed sedimentary rocks.
The red, orange and white colors of the rocks provide spectacular views for park visitors.
Thank you for your comments,

Amazing rock formation at Lulworth cove , there is so much erosion at this beautiful location , not sure how long its all going to last :(
Þingvellir was the site of the Alþing, the annual parliament of Iceland from the year 930 until the last session held at Þingvellir in 1798. Since 1881, the parliament has been located within Alþingishúsið in Reykjavík.
Þingvellir is now a national park in the municipality of Bláskógabyggð in southwestern Iceland, about 40 km (25 miles) northeast of Iceland's capital, Reykjavík. Þingvellir is a site of historical, cultural, and geological significance, and is one of the most popular tourist destinations in Iceland. The park lies in a rift valley that marks the crest of the Mid-Atlantic Ridge and the boundary between the North American and Eurasian tectonic plates. To its south lies Þingvallavatn, the largest natural lake in Iceland.
Þingvellir National Park was founded in 1930, marking the 1000th anniversary of the Althing. The park was later expanded to protect the diverse and natural phenomena in the surrounding area, and was designated as a World Heritage Site in 2004.
Þingvellir became a national park as a result of legislation passed in 1928 to protect the remains of the parliament site, thus creating the first national park in Iceland. The park was decreed "a protected national shrine for all Icelanders, the perpetual property of the Icelandic nation under the preservation of parliament, never to be sold or mortgaged.
According to the Book of Settlements (Landnámabók), the settlement of Iceland began in 874, when the Norwegian chieftain Ingólfr Arnarson became the first permanent Norwegian settler on the island. Over the next centuries, people of Norse and Celtic origin settled in Iceland. Early on, district assemblies were formed, but as the population grew, there was a need for a general assembly. The descendants of Ingólfur who dominated the region of southwest Iceland had become the most powerful family in the country, and other chieftains felt a need for a general assembly to limit their power.
Grímur Geitskör was allotted the role of rallying support and finding a suitable location for the assembly. At about the same time, the owner of Bláskógar (the contemporary name for the Þingvellir region) was found guilty of murder. His land was declared public, and then obligated to be used for assembly proceedings, and the building of temporary dwellings, and the forest to be used for kindling and the grazing of horses. The Þingvellir area was chosen for this reason and for its accessibility to the most populous regions of the north, south and west. The longest journey a goði (chieftain) had to travel was 17 days, from the easternmost part of the country where mountains and glacial rivers proved bothersome obstacles.
The foundation of the Icelandic parliament is said to be the founding of the nation of Iceland, and the first parliamentary proceedings in the summer of 930 laid the ground for a common cultural heritage and national identity. Þingvellir played a central role in the history of the country, and its history runs almost parallel with the history of the Icelandic Commonwealth.
This week's theme for Mosaic Montage Monday was Geological. Sunlight rising on a montage of local geology. HMMM!
Huonglong National Scenic Park.
Over millennia of geological change, mineral deposits built up and naturally created the travertine pools of Huanglong. Formed out of limestone, the hot springs rose to varied levels, making the light blue water cascade over waterfalls into other series of pools and even hollowing out caves along the valley. With rugged, snow-capped peaks on both sides, the slicing river of hot springs looks almost like a dragon, earning the title of “Yellow Dragon.”

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!
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 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.
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.
A side view of the 17th century gatehouse to the Lanhydrock estate in Cornwall. Magmatic intrusion materials, such as granite, form the geological skeleton of the Cornish topography. Since prehistoric times, granite has been used whenever the mark of permanence was required: we were here!
Me, taking a picture of the sunrise from Ponta das Contendas on the island of Terceira in the Azores, Portugal. I am holding Juca's camera while he is taking my picture with mine. I had a great time on my day long photo tour with Juca. Expect for a lunch break at the Santa Caterina Restaurant in Praia da Vitória, we took photos fro Sunrise to Sunset. Make sure to schedule a tour with him at Azores Explorations if you should ever go to the Terceida.
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.

Long lake sits beside the Beartooth Highway in Wyoming. The lake which is surrounded by outcrops of Archean gneiss is one of the hundrends of glacial lakes on the plateau which were the result of Pleistocene glaciation.
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.

Toadstool Geologic Park is located in the Oglala National Grassland in far northwestern Nebraska. It is operated by the United States Forest Service. It contains a badlands landscape and a reconstructed sod house. The park is named after its unusual rock formations, many of which resemble toadstools.
