Question: D1  was closed when this agency, created in 1916, petitioned to allow climbing

Context paragraphs:
D1 (Longs Peak): The D1 is the original technical climbing route up The Diamond of Longs Peak.  In 1954, when National Park Service was petitioned to allow climbing on The Diamond they responded with an official closure.  Climbing on The Diamond was banned until 1960.  When the ban was lifted later that year, Dave Rearick and Bob Kamps were the first to climb the Diamond via a route that would come to be known simply as "D1".  This route would later be listed in Allen Steck and Steve Roper's influential book "Fifty Classic Climbs of North America".  Today the route is not necessarily regarded as the best of its grade on The Diamond, some consider other routes to be of higher quality.  The easiest and most popular route on the face, the "Casual Route" (5.10-), was first climbed in 1977.

Climbing lane: Climbing lanes are a roadway lane design typically used on Interstate highways.  They allow slower travel for large vehicles, such as large trucks or Semi-trailer trucks, ascending a steep grade.  Since climbing uphill is difficult for these vehicles, they can travel in the climbing lane without slowing traffic.

Bouldering: Bouldering is a form of rock climbing that is performed on large boulders, small rock formations or artificial rock walls, without the use of ropes or harnesses.  While it can be done without any equipment whatsoever, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and provide a firmer grip, and bouldering mats to prevent injuries from falls.  Unlike free solo climbing, which is also performed without ropes, bouldering problems (the path that a climber takes in order to complete the climb) are usually less than 6 meters (20 ft.) tall.  Artificial climbing walls allow boulderers to train indoors in areas without natural boulders.  Bouldering competitions, which employ a variety of formats, take place in both indoor and outdoor settings.

Park Avenue (BMT Jamaica Line): Park Avenue was a station on the BMT Jamaica Line.  It had two tracks and an island platform.  It was opened on June 25, 1888, and closed on June 5, 1916.  The station closed due to proximity to stations at Flushing Avenue and Myrtle Avenue.  It was demolished to allow for the Dual Contracts rebuilding of the Jamaica Line.  As part of the rebuilding, the line was given a third track, stations were given side platforms, a connection to the Myrtle Avenue Elevated was installed and the elevated was strengthened to allow for subway cars to use the line.

Glenn Exum: Glenn Exum (June 24, 1911 – March 17, 2000) numbers among the premier mountaineers in American climbing history.  Exum is best remembered for ascents in the Teton Range.  In 1931, while only in his teens, Exum was the first to climb the exposed ridge to the summit of Grand Teton which now bears his name.  The Exum Ridge remains one of the most popular routes to the summit of Grand Teton.  After traveling Europe and seeing mountain guides there essentially pull their clients up the mountain, Exum, along with his friend Paul Petzoldt, founded a climbing school to teach clients climbing skills to allow them to fully participate in ascending the mountain.  The school they founded, now known as Exum Mountain Guides, still operates today within Grand Teton National Park.

The Access Fund: The Access Fund is a not-for-profit rock climbing advocacy group in the US.  Their goals are twofold.  First, keeping climbing areas open and gaining access to currently closed climbing areas.  Second, they promote an ethic of responsible climbing and conservation of the climbing environment.  The Access Fund was originally the access committee of the American Alpine Club and was created as the climbing community realized the need for an organization to represent climbing and climbers' rights in the US.

Nintendo Research &amp; Development 1: Nintendo Research and Development 1 (任天堂開発第一部 ) (R&D1) was Nintendo's oldest development team.  Its creation coincided with Nintendo's entry into the video games industry, and the original R&D1 was headed by Gunpei Yokoi.  The developer has created several notable Nintendo series such as "Metroid", "Tetris", "Mario Bros.", and "Donkey Kong".

Climbing garden: In climbing, a climbing garden is usually an outcrop of rock equipped with bolts to allow a form of rock climbing known as sport climbing.  Usually the routes in a climbing garden are short and are used mainly as introductory climbs by professional climbing schools or instructors, to introduce the novice to rock climbing in a fairly safe environment.  Climbing gardens are found in both France and Switzerland, where they are recognized as a way of developing tourism.

Manchester Wall: Manchester Wall, located in downtown Richmond, Virginia, U.S., is one of central Virginia's premier rock climbing areas, offering multiple routes for trad climbing, sport climbing, and top roping.  The sixty-foot granite wall is a remnant of the Richmond and Petersburg Railroad Bridge which spanned the James River for much of the nineteenth century.  The climbing area is located on the south side of the James River and is accessible by foot from the north via Brown's Island and the T. Tyler Potterfield Memorial bridge, also known as the Brown's Island Dam Walk.  There are also two parking lots that allow walk-up access from the south; one on W 7th Street and Semmes Avenue, and the Floodwall parking lot located at the south end of the Mayo Bridge.  The routes offered at Manchester Wall, and its 3 adjacent pillars, are superb for recreational and experienced climbers alike.

National Park Service: The National Park Service (NPS) is an agency of the United States federal government that manages all national parks, many national monuments, and other conservation and historical properties with various title designations.  It was created on August 25, 1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior.  The NPS is charged with a dual role of preserving the ecological and historical integrity of the places entrusted to its management, while also making them available and accessible for public use and enjoyment.
