Chesapeake & Ohio Canal

https://www.nps.gov/choh/index.htm https://en.wikipedia.org/wiki/Chesapeake_and_Ohio_Canal_National_Historical_Park The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the states of Maryland and West Virginia. The park preserve the remains of the Chesapeake and Ohio Canal and many of its original structures. The canal and towpath trail extends along the Potomac River from Georgetown, Washington, D.C., to Cumberland, Maryland, a distance of 184.5 miles (296.9 km). Preserving America's early transportation history, the C&O Canal began as a dream of passage to Western wealth. Operating for nearly 100 years the canal was a lifeline for communities along the Potomac River as coal, lumber, and agricultural products floated down the waterway to market. Today it endures as a pathway for discovering historical, natural, and recreational treasures. The park has numerous access points. There is no main entrance. In Washington, DC, the C&O Canal begins in Georgetown on 29th Street NW, south of M Street, and runs alongside Canal Road / Clara Barton Parkway out of DC to the west.

A spotted lanternfly with wings spread showing namesake spots Series: No Time for Games The Civil War affected more than the soldiers on the battlefield. An entire generation was shaped by their perception of events during this critical chapter of American history and the weight of war was borne on little shoulders as well as large. Whether they snuck into the army, served as drummer boys, helped tend the wounded, or faced every day as a struggle to stay alive, the perspectives of children offer unique insight into the effects of the Civil War. "The great objects in life were Photograph of a Union family at a military camp Series: Born of Earnest Struggle When the Civil War began in 1861, President Abraham Lincoln's primary concern was saving the Union and preventing the fracturing of the nation. After the failure of the Peninsula Campaign in the summer of 1862, Union morale was low. The northern economy was shaky, optimism for victory had faded, and Lincoln's Cabinet feared growing Confederate strength would encourage foreign intervention. Lincoln began to see freeing the slaves, not as a constitutional dilemma or a moral choice, but as a way of Photograph of unnamed Union African American troops Series: Geologic Time Periods in the Paleozoic Era During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era. fossil corals in a rock matrix Series: The Lost Orders As Lee invaded the north he hoped to rally the support of the people of Maryland, resupply his exhausted army, and draw the Union army far beyond its supply depots and fortifications, where they might be dealt a more decisive blow.

A lost copy of the order was left behind in a field near Frederick, MD wrapped in an env Photograph of Robert E. Lee Series: A Savage Continual Thunder In September 1862 Confederate Gen. Robert E. Lee changed the course of the Civil War. By crossing the Potomac River he moved from defending the south and its people to invading northern territory. He hoped that a major victory on Union soil would encourage European recognition of the Confederacy, crush northern morale, and force President Lincoln to sue for peace. As the Union Army of the Potomac scrambled to meet the Southern threat, President Lincoln hoped that Lee's invasion would lead to a U Lithograph of Battle of Antietam Four Locks Cultural Landscape The Four Locks is a component landscape of the Chesapeake and Ohio Canal. The inventory unit is about 950 acres and is located southwest of Clear Springs, Maryland.

A forest with healthy green leafed beech trees Overview of the Urban Forests The eight urban forests measured in the Urban Ecology i-Tree analyses are diverse. The following articles explore just a few of the common ecological benefits the urban trees in these parks provide to the parks and the surrounding areas. Overview of the Urban Forests icon of tree silhouettes. Icon put over photo of Prince William Forest Avoided Runoff and Urban Forests Surface runoff, particularly from storms, can be a cause for concern in many urban areas because the large amounts of paved surfaces will increase the amount of water that cannot soak into the ground. These large volumes of stormwater runoff can carry surface impurities into streams, wetlands, rivers, lakes, and oceans, contributing pollution, garbage, and excessive nutrients into aquatic ecosystems. Urban forests, however, are beneficial in reducing surface runoff. Avoided Runoff icon of rain over a tree branch. Icon put over raindrops on red fall leaves Carbon Storage by Urban Forests Climate change is an issue of global concern. Urban trees can help mitigate climate change by storing carbon in tree tissue and sequestering atmospheric carbon from the key greenhouse gas, carbon dioxide (CO2). Carbon Storage & Sequestration icon of CO2 going into a tree. Icon put over photo tree trunk. Air Pollution Removal by Urban Forests Poor air quality is a common problem in many urban areas. It can lead to decreased human health, damage to landscape materials and ecosystem processes, and spoiled scenic views due to reduced visibility. The National Park Service monitors and assesses air quality in park units. The trees in NPS’s urban forests contribute to improved air quality. Air Pollution Removal Icon of green lungs. Icon put over photo of tree canopy gap. Structural Values of Urban Forests A tree’s structural value can be thought of as the cost of having to replace a tree with a similar tree. It can be calculated with factors like the tree trunk area and the tree’s health condition. Various insects and diseases can infest urban forests, potentially killing trees and reducing the health, structural value and sustainability of the urban forest. Structural Values of Trees icon of tree on field. Icon put over photo of snow covered trees. Other Benefits of Urban Forests Other benefits of urban forests include: Trees and Building Energy Use and Oxygen Production. Trees affect energy consumption by shading buildings, providing evaporative cooling, and blocking winter winds. Oxygen production is one of the most commonly cited benefits of urban trees. Other Tree Benefits icon of house with a tree besides it.
