View search results on mapBuilt in 1958, Scattergood looms above the beach at Playa Del Rey. It is one of four gas-fired power plants built by LADWP, which provide around a quarter of the utility’s energy for the city. It has three gas-fired units, and produces around 800 megawatts. It is named after Ezra Scattergood, who was the first chief of the electrical side of the DWP (while William Mulholland handled the more notorious water side).
This gas-fired power plant in the San Fernando Valley, built in 1953, is the oldest of the four gas-fired plants operated in the basin by DWP. Two of its units have been shut down (#1 and 2), two have been upgraded (#3 and #4), and three new, more efficient ones were added around ten years ago. The total output for the plant is around 600 megawatts. East of the plant is the Truesdale Training Center, the DWP main training site for electrical workers.
The DWP Haynes Generating Station in Long Beach has six units and generates up to 1,580 megawatts. It is the largest of the four gas-fired power plants built by LADWP, which provide around a quarter of the utility’s energy for the city.
The DWP Harbor Generating Station is a gas fired plant in Wilmington that generates 450 megawatts. It is one of four gas-fired power plants built by LADWP, which provide around a quarter of the utility’s energy for the city.
The Sylmar Converter Station is where the high voltage DC line from Bonneville Power Administration plants along the Columbia River comes into Los Angeles. Known as the Pacific Intertie, this is one of the longest DC lines in the world, carrying as much as 3,000 megawatts at 500,000 volts DC over 850 miles, without a stop. The original inverter station at Sylmar, constructed in the 1960s, was gradually replaced by a new one, across the highway, which took over the full load in 2004.
The Adelanto Converter Station, located in the desert near Victorville, northeast of Los Angeles, is where the high voltage DC line from the Intermountain Power Plant makes its first stop on the 500 mile journey to Los Angeles from Utah. The facility converts the 500,000 volt DC current to AC, and sends it down to the Rinaldi Receiving Station and Receiving Station E, in the San Fernando Valley.
The main complex for the Los Angeles Department of Water and Power (DWP)'s dust mitigation project at Owens Lake is this office and engineering complex next to the lakebed south of Keeler. The DWP has spent more than a billion dollars on the lakebed, developing, installing, and maintaining systems covering around 50 square miles, intended to reduce the dust that blows off the surface of the lake.
La Poudre Pass is a remote area at the northwest corner of Rocky Mountain National Park, at the headwaters of the Colorado River. There is a small pond there that could be considered the ultimate source of the great river, that drains much of the west slope of the Rockies, and the southwestern USA.
Milner Pass, on the Continental Divide inside Rocky Mountain National Park, is along US Highway 34, known as the Trail Ridge Road, which is the highest paved through-road in the nation. It reaches a peak of 12,183 feet a few miles east of Milner Pass. The road was constructed from 1926 to 1932, and is closed for the winter when it is covered in drifts up to 35 feet deep. There is a visitor center along the road between the pass and the high point. It’s at an elevation of 11,796 feet.
The highest paved road in the country dead-ends at the highest paved parking lot in the country, at the summit of Mount Evans, at 14,130 feet. There is a small observatory at the summit, the Meyer-Womble Observatory, and the preserved ruins of the Crest House, which was known as the “highest structure in the world” when it was finished in 1941. It was mostly destroyed in a propane explosion in 1979.
A 13-mile long ten-foot wide water tunnel runs under Rocky Mountain National Park, from one end to the other, crossing 3,700 feet under the Continental Divide. It is the fulcrum of a network of trans-basin, trans-divide reservoirs and pipelines known as the Colorado-Big Thompson project, built by the U.S. Bureau of Reclamation, and completed in 1947, at a cost of $160 million.

The Farr Pumping Station lifts water out of Lake Granby up a hundred feet more in elevation to the Shadow Mountain Reservoir and Grand Lake. The water is siphoned out of the lake at the western portal of the Alva B. Adams Tunnel, where it flows under Rocky Mountain National Park to the other side of the Continental Divide, and flows down hill to urban users on the Front Range.
The Colorado River enters the Shadow Mountain Reservoir as a somewhat wild stream, emerging from its headwaters at La Poudre Pass, 20 miles north. At the Shadow Mountain Reservoir, its waters become part of a captured hydraulic infrastructure, and a fully controlled resource, all the way to Mexico, where whatever is left dribbles into the Pacific.
A railroad was built over the Continental Divide at Rollins Pass in 1903. At 11,677 feet, it was the highest non-cog railway in the nation. Much of the route was covered with wooden snowsheds, but snow removal was always a problem, and the route was meant to last just until a tunnel could be built at a much lower elevation, away from the snowdrifts, and without all the curves and the four percent grades.
The west portal of the Moffat Rail Tunnel is at Winter Park, a ski resort, developed by the city of Denver, and the largest municipal ski development in the nation. It opened in 1939, with its first ski lift, built by the WPA, and grew quickly into a major ski resort, owned by Denver’s parks department until the city sold it to a private company in 2002. A weekend “ski train,” which started in 1940, still connects the slopes to downtown Denver, 65 miles away by train.
The Moffat Water Tunnel is a ten foot diameter water tunnel running parallel to the larger train tunnel. It was made at the same time as the train tunnel, starting in 1924, as the preliminary “Pioneer Bore” 75 feet south of the main train tunnel. Both run for more than six miles under and over the Continental Divide. The Moffat Water Tunnel has been used as a water supply tunnel for the city of Denver since 1936.
Berthoud Pass, on the Continental Divide, is crossed by Highway 40. A plaque dated 1929 says the pass was discovered and surveyed by Captain E.L Berthoud in 1861, aided by Jim Bridger. A toll road opened in 1874, and an improved highway opened in 1923.
There is an electronics telemetry site on the hilltop above Berthoud Pass, known as the Mines Peak Electronic Site, located directly on the Continental Divide. It has been used as a microwave relay site to convey communications across the nation since 1959, and has a heavily reinforced AT&T microwave relay tower, built in the 1970s. There is also weather monitoring equipment at the site.
The meeting point of the Vasquez and Gumlick water tunnels, part of Denver’s water supply, is contained in a small maintenance facility operated by Denver Water, on the easterm side of the Continental Divide. The three-mile long Gumlick Tunnel passes under the Divide invisibly, two thousand feet below the crest of Jones Pass, which tops out at 12,454 feet.
The Henderson Mine is the largest molybdenum mine in the nation, which has produced more than a billion pounds of the material from this site since opening in 1976. At the mine, the rock-bearing ore is blasted out of the living rock, and is crushed down to soccer ball sized or smaller chunks, that dump onto a conveyor belt. This all takes place half a mile underground, with little to see on the surface except huge vents, the elevator headframe, and other support structures.
Purdue University Reactor Number One (also known as PUR-1), is currently the only functioning nuclear reactor in the state of Indiana. Its main purpose is as a pedagogical tool, facilitating the training and teaching of Purdue University nuclear engineering students. Although originally designed with a total output capacity of 10kW, it currently operates at 1kW. Its operating license was issued in 1962, by the then Atomic Energy Commission.
The Kewaunee Nuclear Power Station is a closed nuclear plant located in Carlton, Wisconsin, adjacent to Lake Michigan, once the source of its cooling water. The plant had a 566MW pressurized water reactor, which operated from 1973 until 2013, when owner/operator Dominion Energy announced it would be closing the plant due to its inability to compete with lower cost natural gas.
Hunter Power Plant is located in Castle Dale, a part of eastern Utah with local coal production. It is home to three coal-fired units, whose combined nameplate output capacity is 1,577 MW. The plant became operational in stages, as each unit was copleted, between 1978 and 1983. It is operated by majority-owner PacifiCorp, a subsidiary of Bekshire Hathaway Energy.
The Harrington Power Plant is northeast of Amarillo, Texas, in the Texas Panhandle. The plant contains three coal-fired units whose combined output capacity is 1,018MW. Units 1, 2, and 3 became operational in 1976, 1978, and 1980 respectively. Most of the coal burned by the plant comes from Wyoming's Powder River Basin, while at least a portion of its water supply consists of recycled wastewater from Amarillo.
The Kingston Power Plant is a large coal-fired power plant, built by the Tennessee Valley Authority (TVA) in the 1950s.
The Highland Park plant though, north of downtown Detroit, was where Ford’s assembly line method was proven, changing the world of mass production. When it opened in 1910, to assemble the Model T, it had 90 acres under one roof, nearly 4 million square feet, the largest manufacturing plant in the country.
The Chrysler Headquarters and Technology Center, in Auburn Hills, Michigan, north of Detroit, has 5,300,000 square feet, and a contiguous office complex with a central building that is half a mile long. Chrysler, (now Fiat Chrysler), sells around 2.2 million cars per year and has five assembly plants in the USA, ranging from 2 to 5 million square feet.
Honda opened the Marysville plant in 1982. It has 3.6 million square feet and 4,200 employees, making Accords and Acuras. It is one of four Honda assembly plants in the USA, making most of the 1.6 million Hondas sold in the USA every year. It is located next to another, the East Liberty Plant.
