Navajo Sandstone

Navajo Sandstone is a geological formation in the Glen Canyon Group, spread across the U. S. states of southern Nevada, northern Arizona, northwest Colorado, Utah as part of the Colorado Plateau province of the United States. The Navajo Sandstone is prominent in southern Utah, where it forms the main attractions of a number of national parks and monuments including Red Rock Canyon National Conservation Area, Zion National Park, Capitol Reef National Park, Glen Canyon National Recreation Area, Grand Staircase-Escalante National Monument, Canyonlands National Park. Navajo Sandstone overlies and interfingers with the Kayenta Formation of the Glen Canyon Group. Together, these formations can result in immense vertical cliffs of up to 2,200 feet. Atop the cliffs, Navajo Sandstone appears as massive rounded domes and bluffs that are white in color. Navajo Sandstone occurs as spectacular cliffs, cuestas and bluffs rising from the desert floor, it can be distinguished from adjacent Jurassic sandstones by its white to light pink color, meter-scale cross-bedding, distinctive rounded weathering.

The wide range of colors exhibited by the Navajo Sandstone reflect a long history of alteration by groundwater and other subsurface fluids over the last 190 million years. The different colors, except for white, are caused by the presence of varying mixtures and amounts of hematite and limonite filling the pore space within the quartz sand comprising the Navajo Sandstone; the iron in these strata arrived via the erosion of iron-bearing silicate minerals. This iron accumulated as iron-oxide coatings, which formed after the sand had been deposited. After having been buried, reducing fluids composed of water and hydrocarbons flowed through the thick red sand which once comprised the Navajo Sandstone; the dissolution of the iron coatings by the reducing fluids bleached large volumes of the Navajo Sandstone a brilliant white. Reducing fluids transported the iron in solution. Where the oxidizing and reducing fluids mixed, the iron precipitated within the Navajo Sandstone. Depending on local variations within the permeability, porosity and other inherent rock properties of the sandstone, varying mixtures of hematite and limonite precipitated within spaces between quartz grains.

Variations in the type and proportions of precipitated iron oxides resulted in the different black, crimson, orange, peach, pink and yellow colors of the Navajo Sandstone. The precipitation of iron oxides formed laminea, corrugated layers and pipes of ironstone within the Navajo Sandstone. Being harder and more resistant to erosion than the surrounding sandstone, the ironstone weathered out as ledges, fins, "flags", other minor features, which stick out and above the local landscape in unusual shapes; the age of the Navajo Sandstone is somewhat controversial. It may originate from the Late Triassic but is at least as young as the Early Jurassic stages Pliensbachian and Toarcian. There is no type locality of the name, it was named for the'Navajo Country' of the southwestern United States. The two major subunits of the Navajo are the Shurtz Sandstone Tongue; the Navajo Sandstone was named as the uppermost formation of the La Plata Group by Gregory and Stone in 1917. Baker reassigned it as the upper formation of Glen Canyon Group in 1936.

Its age was modified by Lewis and others in 1961. The name was not used in northwest Colorado and northeast Utah, where the name'Glen Canyon Sandstone' was preferred, its age was modified again by Padian in 1989. A recent radioisotopic analysis suggests that the Navajo Sandstone formation is Jurassic, extending for about 5.5 million years from the Hettangian age to the Sinemurian age. The sandstone was deposited in an arid erg on the Western portion of the Supercontinent Pangaea; this region was affected by annual monsoons that came about each winter when cooler winds and wind reversal occurred.

Theropod tracks are geographically located in Arizona and Utah, USA. Ornithischian tracks located in Arizona, USA; the Navajo Sandstone is well known among rockhounds for its hundreds of thousands of iron oxide concretions. Informally, they are called "Moqui marbles" and are believed to represent an extension of Hopi Native American traditions regarding ancestor worship. Thousands of these concretions weather out of outcrops of the Navajo Sandstone within south-central and southeastern Utah within an area extending from Zion National Park eastward to Arches and Canyonland national parks, they are quite abundant within Grand Staircase-Escalante National Monument. The iron oxide concretions shapes, their shape ranges from spheres to discs. Although many of these concretions are fused togethe

Joan Glass

Elizabeth Joan Glass, was an English textile designer and painter. Glass was born in Kent, she was the oldest of three daughters born to Edith Mary Muirhead. Her father, was a senior partner and chairman of James Templeton & Co one of the leading makers of carpets in Britain. After her schooling Glass studied art at Chelsea Polytechnic in London. One of her teachers was neo-Romantic Graham Sutherland. At this time she was influenced by Sutherland as well as Vincent van Gogh. During the war Glass worked in military censorship. After her marriage, she became known as Joan Clifford-Smith but continued to sign her work under her maiden name, she is best known for her textile designs and one of her carpet designs became one of the biggest selling commercial carpets available in Britain during the 1950s and 60s. In 1952 she moved to Buck's House in Essex. While in Great Bardfield and her husband became friendly with the village art community known as the Great Bardfield Artists, they organised a series of large open house exhibitions during the 1950s, which attracted thousands of visitors.

Glass exhibited pictures at all these shows. Known for her fine sense of colour her textiles and paintings were semi-abstract in design; some of her work is included in the collection of the Fry Art Gallery in Essex. The Bardfield art community fragmented in the early 1960s and Glass and her family moved to London before relocating to Little Baddow Hall, near Chelmsford, Essex. During this time the artist’s output was restricted to making and decorating ceramics, Following the example of the earlier Bardfield summer exhibitions, Glass established in 1971 a series of large summer art festivals at her Essex home; these were popular with the local art community and in 1974 she converted her house and established the Little Baddow Hall Arts Centre. Musicians and artists attracted to the centre included Howard Shelly, the Medici Quartet, John Miller and Andy Warhol, as well as prominent local artists Geoffrey Burnand, John Doubleday and Humphrey Spender. According to her obituary, the Arts Centre’s ‘enormous popularity was due in no part to Joan’s own stamp of style and sophistication, combined with a welcoming lack of pretension.'

Despite its popularity with the mid Essex art community, the arts centre closed in 1979 and in 1990 she moved to a smaller house in Little Baddow. During the Second World War, she served in the navy where she met artist Stanley Clifford-Smith and they married shortly after the end of the war; the couple moved to Suffolk in East Anglia where they both designed fabrics. After the death of her husband she abandoned art practice for the role of art patron. Joan Glass died in an Essex nursing home in 2000.

Kyboe! is a Dutch upscale fashion watch brand founded in 2007 by Dutch natives Dick Sijmons and Kees de Bruïne. KYBOE! Watches are known for bright colors. In 2015 the company set up a U. S. office in Boca Raton, when American partners Marc Bell and Joseph Roos acquired a stake in the company. Dick Sijmons and founder, began making bright, fashionable plastic watches in 2007. After seeing a positive response within the Netherlands, he expanded the offerings to include more durable stainless steel cases; these steel watches were a huge success, in 2008, the plastic watches were phased out entirely. Kyboe! Gained a strong following in its home country of the Netherlands. To grow their customer base, Sijmons brought Kyboe! to St. Tropez in the South of France, as well as the Spanish island of Ibiza; the pair signed agreements with individual retailers in each location to start selling Kyboe! and soon had reached over 200,000 watches sold in the Netherlands, St. Tropez and Ibiza alone. New York–born entrepreneur Marc Bell discovered Kyboe! in 2008 while vacationing in St. Tropez.

He purchased six watches and returned home to the U. S. where business partners complimented the watches often. Every year, Bell returned to St. Tropez and purchased more Kyboe! watches. In 2014, after having a difficult time importing Kyboe! to the U. S. Bell decided, he reached out to founders Sijmons and de Bruïne, who were unsure that Kyboe! was ready for the American market. The founders denied Bell’s request to become a local distributor; as a successful businessman, Bell recognized the brand’s potential and, in 2015, approached Sijmons and de Bruïne with an offer to purchase a portion of the company and become partners. The offer was accepted and the deal was signed in the Spring of 2015; as part of the transaction, Bell brought business partner Joseph Roos, an expert in retail and finance, in to the partnership. Today, the company is headquartered in Boca Raton, with additional operations in The Netherlands and Hong Kong. Kyboe! is sold by more than 2000 independent retailers around the world.

In addition, KYBOE! is sold by major retailers including Saks Fifth Avenue and Lord and Taylor, with new partnerships being announced. Marc Bell, president and CEO of Kyboe!, wants to expand the line to include bracelets and other accessories over the next 12 months. Kyboe!’s first brand ambassador, DJ Vinny Vinsane, joined the team on March 3, 2016. Vinsane DJs for well-known venues throughout West Palm Beach, is known for his role on ABC’s The Bachelorette. Separate from Kyboe!’s growing list of ambassadors, a number of celebrities have been spotted wearing Kyboe! Including supermodel Kim Kötter. George Takei. KYBOE! Official Website KYBOE!
