Lake Powell Water Level to Drop 2.5 feet

It’s SCIENCE!

From November 18-23, 2012, the Department of Interior will conduct the first High Flow Experiment under a multi-year High Flow Protocol announced earlier this year by Secretary Salazar. Under this Protocol, high flow releases are linked to sediment input and other resource conditions below Glen Canyon Dam.

Beginning on the evening of November 18th, releases from Glen Canyon Dam will begin ramping up to full power plant capacity (approximately 27,300 cfs). At midday on November 19th, bypass tubes at Glen Canyon Dam will be opened and releases will continue to increase up to full power plant and bypass capacity (approximately 42,300 cfs) by the evening of November 19th. Releases will be maintained at peak release for 24 hours and then begin ramping back down. Releases will return to normal operations in the evening of November 23rd. The entire experiment, including ramping is expected to last 5 days, with 24 hours at peak release. November releases from Glen Canyon Dam prior to and after the High Flow Experiment are expected to fluctuate between 7,000cfs and 9,000cfs. The elevation of Lake Powell is expected to decrease approximately 2 ½ feet during the 5-day experiment.

Flower Crab Spider on Desert Sunflower

A recent Facebook post from a friend of mine asking to identify a spider in Illinois reminded me of this time I brought in a Desert Sunflower with a stowaway. In Greenehaven, AZ back in 1997, from the desert behind the house down to Lake Powell was a blooming sea of yellow Desert Sunflower and orange Globe Mallow. I had snipped a couple flowers to display inside and later that day noticed a very well camouflaged spider.

The Flower Crab Spider has the ability to change color by secreting a liquid yellow pigment into the outer cell layer of the body. The spider itself is normally white. My friend had also brought in a Flower Crab Spider on some white flowers. This species habitat actually spans the entire Northern Hemisphere! The Desert Sunflower, however, is native to the Southwest.

Grand Staircase-Escalante Cottonwood Canyon Road

I love the Grand Staircase-Escalante area because of its relatively unspoiled wilderness and unique geography, flora and fauna. It’s a short ways away from Lake Powell and for those who want to see what rugged Southern Utah has to offer it is relative accessible.

Grand Staircase-Escalante National Monument is responsible for land use planning efforts on approximately 1.9 million acres of public land within the Monument’s boundaries in south central Utah. The planning area also includes an additional 200,000 acres of public land that falls within the Glen Canyon National Recreation Area.

Here are some photographs I took on a trip along Cottonwood Canyon Road as a scenic short-cut to Kodachrome Basin and Bryce. And Yes, I was shooting Kodachrome 64.

I brought along a first-aid kit (which I kept on myself), a gallon of water and some trail-mix. It was hot, dusty and absolutely mind-bending – worth the experience in dry weather, 100% to be avoided if wet.

From WikiPedia:

Road 400 (Cottonwood Canyon Road) is a scenic 47 mile dirt road connecting U.S. Highway 89 with Utah S.R 12 at Cannonville. It traverses portions of Grand Staircase-Escalante National Monument offering a unique view into the heart of the Monument. The only other road (Smoky Mountain Road) crossing the entire Grand Staircase is also unpaved, nearly twice as long, and requires at a minimum a high clearance vehicle.

Road 400 is a reasonably good quality dirt road (mostly sand and clay over a sandstone foundation) during dry weather. If the road has been recently graded it may be suitable for passenger cars, however high clearance vehicles are recommended.

Originally constructed as a maintenance road for power lines following the canyon, it is considered impassable in wet weather. Many sections traverse ancient seabed deposits of mudstone, silt, and shale. When wet the clay surface becomes exceptionally slick, rendering even four wheel drive useless. Additionally many drainages cross the road in various locations, and these may wash out during periodic flash flooding, particularly during summer thunderstorms. Even in dry weather the road can be muddy to the point of being impassable in low areas.

Old Paria Movie Set Grand Staircase-Escalante NM Utah

We are continuing down memory lane with the Old Paria Movie Set near Pahreah Townsite, UT. Around 1999 the original structures/facades had been removed much to my dismay after bringing a friend to see it. According to the BLM:

In September 1998, flash floods undermined the buildings and created a safety hazard. In November of 1999, 87 local residents from Kane County, Utah, and Page, Arizona, pitched in to disassemble the Movie Set and salvage the old boards to reconstruct two of the buildings. Meticulous drawings were made of the original structures, but when work began in November 2000, builders determined that most of the salvaged lumber would not be structurally suitable for construction. Even so, the original wood holds special memories, and therefore will be included in the overall design. Plans are underway to incorporate the old boards in interpretive displays for inside and outside the reconstructed buildings.

Unfortunately I have not been back to the movie site since then, so I am curious to see how the reconstruction compares to what I remember.

I have taken numerous photographs of the Paria/Pahreah area because I really loved the “painted” stripes of the surrounding sandstone and mud. What I was missing were photos of the actual set which, although reminded us of a foregone era, were obviously “Hollywood” and didn’t fit into my landscape photographer aesthetic.

Alas, I have found one image of some of the movie set which was built in the early 1960s for the movie Sergeants Three, a Western featuring Dean Martin and Frank Sinatra. It also provided settings for the television series Death Valley Days and Gunsmoke. The last movie filmed there was The Outlaw Josie Wales in 1976.
