The Three Sisters, Monument Valley, 1992, along the Arizona/Utah border, Navajo Tribal Park, a storm is moving in. Black and white image made with Hasselblad 501c and Kodak T-Max 400 film. Negative was then scanned into the computer. The dust was really blowing around, just couldn’t keep it off the lens.

The road home

On the way back to camp after a walk in the bush – the haze is caused by dust blowing in all the way from the sahara through to eastern Guinea and beyond. The Simandou range is Guineas’ highest and is staggeringly beautiful. It is also made out of high grade iron ore and is worth a lot of money. Whilst developing countries grow and developed countries spend, the thirst for steel to build infrastructure, cars, computers and cameras continues… more and more places that were previously out of range will need to be exploited for their resources. This has the potential to bring huge revenue and development to the region. It also, as has happened to often in the past, has the potential to fuel corruption and degradation of society.

Monument Valley Sunset

Monument Valley Sunset

Watching last thursday’s episode of Billy Connolly’s journey down Route 66 inspired me to take another look at my Monument Valley snaps. What a place!

I think I’ve got my settings wrong on my pc/monitor because this looks so much more vibrant on my computer than it does on my iPad. The difference isn’t usually that pronounced but with this shot it’s really apparent.

From :-

Monument Valley is one of the truly iconic places of the United States. It has been the setting for hundreds of Western movies, and its unique sandstone formations are instantly recognizable the world over.

The Valley is home to Navajo families that have lived there for generations.

Monument Valley is a part of the Navajo Nation. It is located on the Utah/Arizona border, east of Highway 163. The park entrance is in Utah. Admission to the park is $5 per person, and free for children under the age of 9.

For visitor information, contact Monument Valley Navajo Tribal Park.

The park is open daily from 6am to 8pm from May through September and from 8am to 5pm from October through April.

Getting there

From Flagstaff, head east on Highway 40 to Highway 89 (Page, Grand Canyon Exit). Travel north on Highway 89 to Highway 160. Travel east on Highway 160 to Highway 163 (Kayenta exit). Travel north into Utah to Goulding’s Lodge then take Indian Route 40 southeast to the entrance to Monument Valley. The closest airport is Farmington, New Mexico. It is about two and a half hours east of the park.

Most of the scenic locations within Monument Valley are found within the Monument Valley Navajo Tribal Park. At the edge of the valley, there is a visitor center, a small convenience store and the Haskenneini Restaurant, which specializes in both native Navajo and American cooking.

As this is not a federal park, National Park Passes or Golden Eagle Passes are not valid here.

“It’s breathtaking. You can’t believe it. It’s very photogenic; it has a kind of mythic feeling of age, of legend. . . . You’ve seen it in the movies, but when you see it in life, it’s so epic in its proportions that it almost stands for the whole of the West.” -Filmmaker Peter Bogdanovich.
