Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Secretary Jewell, Director Jarvis Announce Nine New National Historic Landmarks Highlighting America's Diverse History and Culture
Office of the Secretary

WASHINGTON, D.C. – U.S. Secretary of the Interior Sally Jewell and National Park Service Director Jonathan B. Jarvis today announced the designation of nine new national historic landmarks, ranging from the oldest operating streetcar system in America to the home of an arctic explorer. The sites announced today join 2,544 other sites across the country recognized as places that possess exceptional value and quality in illustrating or interpreting the heritage of the United States.
“These nine sites add to a nationwide network of unique, historic places that represent the complex journey that we have taken as a nation,” said Secretary Jewell. “By designating these new national landmarks we ensure that America's history of innovation, vision and diversity are celebrated today and for future generations.”
“From artists and architecture, to the accomplishments of explorers and entrepreneurs, these sites highlight the mosaic of our nation's historic past,” Jarvis said. “These new national historic landmarks can educate and inspire Americans with their country's rich history, as well as drive tourism and boost local economies.”
The nine national historic landmarks announced today include:
Baltusrol Golf Club, Springfield, New Jersey
Founded in 1895, Baltusrol Golf Club comprises arguably the most important and influential design of leading early-20th-century golf course architect Albert W. Tillinghast (1874 – 1942), one of the first American golf architects to integrate a golf course into nature. Baltsurol has hosted at least one major national championships in every decade of the 20th and 21st centuries, including five U.S. Opens, two U.S. Women's Opens, and one PGA championship. Baltsurol will also host the 2016 PGA championship.
Brown Bridge, Rutland County, Vermont
Constructed in 1880, the Brown Bridge is one of the most outstanding surviving examples of a Town lattice truss, a widely popular construction method throughout the 19th century that could be erected inexpensively by local builders using machine-fabricated woodwork. Brown Bridge was erected by Nichols M. Powers, who built more than 20 substantial covered bridges throughout New England.
Duck Creek Aqueduct, Metamora, Franklin County, Indiana
Constructed around 1846, the Duck Creek Aqueduct is an exceptional example of 19th-century covered bridge construction and is the only surviving historic covered wood aqueduct in the United States. Built as a component of the Whitewater Canal in southeastern Indiana, the bridge represents a rare surviving component of an American canal system that was a significant mode of transportation in the first half of the 19th century.
Eagle Island (Admiral Robert E. Peary Summer Home), Harpswell, Maine
Eagle Island is the longtime residence of arctic explorer Robert E. Peary, whose multiple expeditions to the North Pole brought international recognition to the United States at the turn of the 20th century and made him one of the most admired men in America. Peary acquired Eagle Island in 1881 and built his house in 1904 on a prominent ledge facing north, towards the open sea. The rustic simplicity of the house and its island setting reflect the life and work of a man who spent 23 years exploring the North Pole and the coast of Greenland.
General Motors Technical Center, Warren, Michigan
The General Motors Technical Center (commonly known as the “GM Tech Center”) is one of the most significant works of architect Eero Saarinen, who was among the most important modernist designers of the post-World War II period in the United States. The GM Tech Center marked Saarinen's emergence onto the national stage and was the first of his four influential suburban corporate campuses that represented a sea change in American business facilities. The GM campus represents Saarinen's work not just as a creator of buildings but also as the planner/designer of total environments.
Frances Perkins Homestead, Newcastle, Maine
As Secretary of Labor from 1933-1945, Frances Perkins was the first woman to serve in a presidential cabinet. The homestead is her ancestral home and lifelong summer residence, which she owned and maintained from 1927 until her death in 1965. As Secretary of Labor from 1933-1945, Perkins was a figure of undisputed national significance and the driving force behind New Deal programs such as Social Security, unemployment insurance, and minimum wage that still provide financial security for all Americans to this day.
Lydia Pinkham House, Lynn, Massachusetts
Lydia Pinkham was the creator and marketer of Lydia Pinkhams' Vegetable Compound, one of the most widely-marketed patent medicines of the late 19th and early 20th centuries, and one of the most well-known businesswomen of her era. The Pinkham Vegetable Compound served, in part, as an impetus for reform of the manufacture and sale of medications as it was routinely cited in the many exposés detailing the excesses and dangers of patent medicines. The 1906 Food and Drug Act, which was passed in the wake of these exposés, resulted in one of the most dramatic shifts in terms of patient expectations and treatment of illnesses during the 19th and 20th centuries.
The Research Studio (Maitland Art Center), Maitland, Florida
Founded in 1937 as an artist colony by architect and artist J. Andre Smith, The Research Studio is a nationally significant example of Art Deco-Mayan Revival architecture and decoration and is one of the most distinctively rendered sites of this style in the United States. More than 200 reliefs, carvings, and sculptures—incorporating hundreds of separate pieces—are integrated into the artists' campus and surrounding tropical landscape. Smith's architectural and decorative interpretations of Mayan culture are an exceptional example of Art Deco fantasy and Mayan Revival art and architecture in the United States.
The St. Charles Line, New Orleans, Louisiana
The St. Charles Line is the nation's oldest operational street railway, a transportation method that at its peak carried nearly 16 billion passengers nationwide each year, and is the only streetcar system dating from that period to remain in operation. The St. Charles Line is also significant for its 35 arch-roofed, steel-bodied Perley Thomas streetcars, which represent an evolution in the engineering of street railway technology. The cars have continuously operated on the line's tracks since 1923-24. Of the tens of thousands originally manufactured, the St. Charles Line's cars are the only conventional streetcars to have remained in operation within their original system.
Jewell also announced a name and boundary change for the Kuerner Farm National Historic Landmark in Chadds Ford Township, Pennsylvania, originally designated in 2011. Renamed Andrew Wyeth Studio and Kuerner Farm National Historic Landmark, the site now includes the converted schoolhouse that artist Andrew Wyeth used as his primary studio from 1940 until a few months prior to his death in January 2009.
The National Historic Landmarks Program, established in 1935, is administered by the National Park Service on behalf of the Secretary of the Interior. The agency works with preservation officials, private property owners, and other partners interested in nominating properties for National Historic Landmark designation. Completed nominations are reviewed by the National Park System Advisory Board, which makes recommendations for designation to the Secretary of the Interior. If selected, property ownership remains the same but each site receives a designation letter, and is eligible for technical preservation advice. The National Historic Landmarks Program is one of more than a dozen programs administered by the National Park Service that provide states and local communities technical assistance, recognition, and funding to help preserve our nation's shared history and create close-to-home recreation opportunities.
