Great Falls

https://www.nps.gov/grfa/index.htm https://en.wikipedia.org/wiki/Great_Falls_Park Great Falls Park is a small National Park Service (NPS) site in Virginia, United States. Situated on 800 acres (3.2 km2) along the banks of the Potomac River in northern Fairfax County, the park is a disconnected but integral part of the George Washington Memorial Parkway. The Great Falls of the Potomac River are near the northern boundary of the park, as are the remains of the Patowmack Canal, the first canal in the United States that used locks to raise and lower boats. At Great Falls, the Potomac River builds up speed and force as it falls over a series of steep, jagged rocks and flows through the narrow Mather Gorge. The Patowmack Canal offers a glimpse into the early history of this country. Great Falls Park has many opportunities to explore history and nature, all in a beautiful 800-acre park only 15 miles from the Nation's Capital. From I-495, take exit 44 for route 193 west; continue 4 miles. Turn right on Old Dominion Drive. Great Falls Park Visitor Center The Visitor Center is currently closed pending needed repairs.

Yet they have a big influence-- they're the most commonly observed sapling in our National Capital Region forests. Pawpaw trees are virtually immune to deer browse and also produce the largest edible fruit native to North America! A hand holds a lumpy green pawpaw fruit Lichens and Air Quality Lichens are durable enough to grow on tree bark and bare rock, yet are sensitive to pollution and air quality. One species in particular was used to track levels of air-borne lead over a 100 year period! Pale green lichen growing on rock. American Eels in the Potomac Watershed American eels are found everywhere along the Atlantic Coast, but many aspects of these fish remain poorly understood. They are perhaps one of the most mysterious fish in the Potomac watershed. Hands hold a 2 to 3 foot long eel over a red container. Summer in the Parks (1968-1976) What began as a summer transportation program to send DC urban youth to Catoctin and Prince William Forest Parks in 1966 grew to a city-wide summer-long festival attracting residents to parks in every quadrant of the city. After the assassination of Martin Luther King, Jr., the program took on an additional role to help save a city from destroying itself.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park Service To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation. A toad sits on red sand, looking into the camera.
