Four Corners 2 Unit 3
Shanae Maerz
Today we're going to piece together a traditional quilt block called Four Corners. When I was a wee girl, we lived in Farmington, NM and I remember going to Four Corners and standing in four states at once - that was pretty cool. So when I saw the name of this quilt block, I just had to do a tutorial on it. I know it probably got it's name from the four patches in the corners but I can pretend that it's named after Four Corners. Let's get started!
From here the Four Corners block goes together like a typical Nine Patch block. Sew the units into 3 rows as shown in the picture below. The seams don't nest together in that middle row so take your time and remember "done is better than perfect"!
If you are wanting to practice making Hourglass units, this is the block for you! The Four Corners block went together quickly. You can change the look of it simply by changing the colors in the center Hourglass unit, or making the four outer Hourglass units out of three colors instead of two. I enjoyed thinking about when I was a girl and living in Farmington while making this tutorial.
I hope you enjoy this Four Corners block too! If you like this tutorial and want to see more, simply click HERE to sign up for my newsletter and receive a free PDF pattern called "Chained Weathervane".
SRP operates and participates in a number of major power plants and generating facilities in Arizona and the Southwest. These generating stations use fuel, steam and nuclear reaction to create energy.
Learn about each generating station below.
The roof of the turbine building and adjacent shade structure house solar panels to power ceiling fans on the public deck. The electricity generated by the plant and solar panels is also fed into SRP's grid.
Horse Mesa Dam is home to three hydraulic turbine-generator units rated at a total of 32 megawatts (MW) plus one reversible pump-turbine (pumped storage) unit rated at 119 MW. The pumped storage unit was installed in 1972 and is capable of either generating electricity or using grid power to pump water onto the upper reservoir, to store energy for later use.
Mormon Flat Dam is named after nearby Mormon Flat, a place where pioneers from Utah stopped to camp on their way to the Valley. The dam, built between 1923 and 1925, stands 224 feet high and 380 feet long.
The dam has one hydraulic turbine-generator rated at 11.5 MW plus one reversible pump-turbine (pumped storage) unit rated at 55 MW. The pumped storage unit was installed in 1971 and is capable of either generating electricity or using grid power to pump water onto the upper reservoir, to store energy for later use.
The Theodore Roosevelt Dam, named after the 26th President of the United States, was among the first projects authorized under the Reclamation Act of 1902, after farmers in the Salt River Valley placed their land on collateral for funding. As completed in 1911, the dam was a dry masonry structure made from large, irregular blocks, which in total stood 280 feet tall. Behind the dam is Roosevelt Lake, the largest reservoir along the Salt River.
In 1989, the Bureau of Reclamation began a project to increase water storage capacity and overall safety of the dam. In addition to raising the original structure and encasing it with concrete, new spillways were installed, power generation was updated, a new bridge was built allowing State Route 188 to be realigned off the dam, and new recreational facilities were created.
Completed in 1996, the modern-day dam stands at 357 feet with a length of 1,200 feet, has a reservoir capable of holding approximately 1.6 million acre-feet, and can produce up to 34 MW of hydropower from a single hydraulic turbine-generator.
Stewart Mountain Dam is named after Stewart Ranch, which used to be located nearby. The dam was built between 1928 and 1930 and stands 212 feet high and 583 feet long. A single hydraulic turbine-generator with a maximum capacity of 13 MW operates based on water order.
Wholly owned by SRP and located in Glendale, Arizona, the Agua Fria Generating Station is a multifaceted energy center that hosts different types of power generation resources, including natural gas steam units, fast-ramping flexible turbines, battery storage and a small solar array. Resources at this site are essential for SRP to deliver reliable electricity on the hottest summer days, helping ensure the safety of families in the Valley.
In fall 2022, two 49.5 MW flexible natural gas units were added to Agua Fria to support SRP in delivering reliable power during the summer. These units have the ability to ramp up and down quickly, responding to peak power demands within 10 minutes, and can rapidly adjust power output to match changing demand. Along with other natural gas units at the station, these resources are critical for delivering reliable power and run only a few hundred hours per year, primarily in the summer. This reduces the amount of time the turbines are running, resulting in minimal environmental impact.
Each power block consists of two combustion turbines, two heat recovery steam generators and one steam turbine. They have a total capacity of 1,100 MW, while all four blocks combined have a total capacity of 2,200 MW.
Wholly owned by SRP, the Desert Basin Generating Station, located in Casa Grande, Arizona, was originally constructed between 1999 and 2001, with SRP purchasing the plant in 2003. This site consists of a combined-cycle, natural gas-fired generating unit with two combustion turbines, two heat recovery steam generators and one steam turbine for a combined capacity of 635 MW. This combined-cycle plant was built with fuel efficiency in mind, and its strength is efficiently providing power that our customers need throughout the year.
Located in Tempe, Arizona, and owned and operated by SRP, Kyrene Generating Station has one combined-cycle, two steam and three combustion turbine generators. The station has a maximum gross capacity of approximately 580 MW.
The original plant is made up of four combined-cycle, combustion and steam generation units, all completed between 1974 and 1975. An additional unit made up of two combustion turbines and one steam turbine began operation in 2005. Another generating unit made up of one combustion turbine and one steam turbine reached commercial operation in March 2006. Together, these units provide a maximum gross capacity of approximately 1,415 MW.
The Dry Lake Wind Power Project, located near Heber, Arizona, is the state's first commercial-scale wind farm. The project is situated on a combination of private, state and Bureau of Land Management public lands.
The Suzlon S88-2.1 MW turbines at this wind power project generate 127 MW of clean, renewable energy. Typically, a 127 MW wind project can generate power for more than 20,000 average homes, according to the American Wind Energy Association's calculation.
SRP owns a share of this station (29% of Unit 1 and Unit 2) located near Craig, Colorado. It has a capacity of 1,283 MW from three units. Each unit is rated at about 428 MW; SRP receives 124 MW each from Unit 1 and Unit 2. Tri-State is the operating agent for the Craig Generating Station.
Forty miles west of downtown Phoenix are three nuclear generating units belonging to Palo Verde Nuclear Station, operated by Arizona Public Service Co. (APS). Palo Verde is the largest nuclear generating station in the United States and the only nuclear generating station not located near a body of water or river. The primary source of water for Palo Verde is recycled waste water from municipalities in the Phoenix metropolitan area.
CAMP VIRGINIA, Kuwait, - The Four Corners Operation, operated by the 553rd Combat Sustainment Support Battalion, 230th Sustainment Brigade, was a busy site when the first convoy of Soldiers arrived from Iraq. The multi-class download site received four convoys redeploying from Iraq, Oct. 18, 2011. Members of the 2-29 Field Artillery Battalion from Fort Bliss, Texas, were some of the first troops to self-redeploy since the directive to reduce the presence of U.S. Forces in that country was publicized.
The Four Corners operation is a 24-hour site with a primary focus on being a one-stop, multi-class download of supplies for self-redeploying units preparing to turn in Theater Provided Equipment. Essentially it is a three part process involving the turn in of ammunition, the briefing of site procedures and turn in of medical supplies, and the actual downloading process of supplies.
Four Corners has been operational and ready to receive Soldiers and equipment for over seven months. "We, the (553rd CSSB), are very excited to be part of the responsible withdrawn of the troops from Iraq. We are very excited to see some of them finally," said Capt. Jocelyn Hayes, acting officer in charge of the Four Corners Operation. With the arrival of this first batch of redeploying units, the operation is now in full swing and being put to the test.
The first of the four convoys arrived in the morning, and the last one made it to Camp Virginia in the late afternoon. "The first convoy had twenty vehicles and ninety seven personnel eager to turn in their equipment," commented Staff Sgt. Jason Parson, noncommissioned officer in charge for incoming convoy lanes. The Four Corners site is set up with multiple lanes to receive various types and quantities of vehicles for downloading of retrograde equipment. These lanes help keep the site moving at full pace, allowing multiple convoys to push through in an expedient manner. "We decided to keep all the vehicles in one lane to have more command and control," Parson said.
After the first convoy was cleared from the lane and escorted to the next stop in the re-deploying site of Four Corners, the 553rd team conducted an after action review of what took place receiving and assisting the convoy with turning-in equipment and properly disposing of hazmat. "Our priority is to safely assist Soldiers with the re-deployment system, but our goal is to minimize the time they have on ground," Parson explained. After traveling hundreds of miles for several hours, if not days, the Soldiers coming into the site are extremely tired, making it evermore pertinent to charge everyone involved with enforcing safety standards.
