Lake Powell Water Level to Drop 2.5 feet


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.

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.

The Big Cut – AZ Highway 89

Although The Big Cut of AZ Highway 89 into the Antelope Mesa on the way between Flagstaff and Page represents man’s forceful domination of the landscape it is also inspiring in terms of its engineering and scale. The cut itself is a wide swath of Kaibab formation blasted and chiseled away to let this thin ribbon of asphalt emerge on top of the mesa.

The south side of the plateau offers brilliant views of the Grand Canyon, Vermillion Cliffs, and Lee’s Ferry. The north side of the plateau is a impossibly (relatively) flat plateau of grasses, sage, mesquite and juniper.

I love this picture for its stark, graphic display. It looks amazing printed. My scan of this slide introduced a light/halo artifact in the cut but I didn’t feel it detracted from the image.
