Use ASCOPE to identify important features.
Virginia (/vərˈdʒɪniə/ ), officially the Commonwealth of Virginia, is a state in the Southeastern and Mid-Atlantic regions of the United States located between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealth’s estimated population as of 2018 is over 8.5 million.
Overview of Virginia
42,775 SQ. MI.
In 1607, 100 English settlers arrived in what is now Virginia to find a robust realm of Native American tribes. They founded their own fort on the southern shore, later known as Jamestown.
VIRGINIA NEWS HEADLINES
A Tale of 2 Virginias
While the colony prospered on tobacco farming, with indentured servants and enslaved Africans sustaining the economy, its Native American ranks were devastated by a “war of extermination” that reduced their numbers from 20,000 to 3,000. Later, as the colony flourished, descendants of those settlers started planning their own independence from England.
After the election of Abraham Lincoln, Virginia became the eighth state to secede from the Union, on April 17, 1861. In the following days, Union Army forces crossed the Potomac River to seize Alexandria, a slave port at the time, to prevent the Confederate Army from having a base so close to Washington.
The surrender of the Army of Northern Virginia that signaled the end of the war was signed at the courthouse in Appomattox on April 9, 1865.
Following the Civil War, Virginia remained generally rural and resisted social changes. The state Legislature enacted a Racial Integrity Act in 1924 barring marriages of “whites” and “coloreds.” In the case of Loving vs. Virginia, the U.S. Supreme Court overturned the state’s interracial marriage ban in 1967.
Virginia still possesses its own North-South divide, with the rural, mountainous reaches of the Blue Ridge Mountains and southwestern valleys and southeastern Tidewater region offsetting the sprawling suburban Washington, D.C., corridor of the northeastern counties.
Virginia’s economy is as diverse as the shipbuilding on the southern shore, the farming and tobacco-growing of rural areas, seafood harvesting along the Atlantic coast and rivers, the apple-growing capital of Winchester in the northwest, wineries spread among the countryside and the technology companies of the suburban Washington corridor.

Geology and terrain
The Chesapeake Bay separates the contiguous portion of the Commonwealth from the two-county peninsula of Virginia’s Eastern Shore. The bay was formed from the drowned river valleys of the Susquehanna River and the James River. Many of Virginia’s rivers flow into the Chesapeake Bay, including the Potomac, Rappahannock, York, and James, which create three peninsulas in the bay.

Deciduous and evergreen trees give the Blue Ridge Mountains their distinct color.
The Tidewater is a coastal plain between the Atlantic coast and the fall line. It includes the Eastern Shore and major estuaries of Chesapeake Bay. The Piedmont is a series of sedimentary and igneous rock-based foothills east of the mountains which were formed in the Mesozoic era. The region, known for its heavy clay soil, includes the Southwest Mountains around Charlottesville. The Blue Ridge Mountains are a physiographic province of the Appalachian Mountains with the highest points in the commonwealth, the tallest being Mount Rogers at 5,729 feet (1,746 m). The Ridge and Valley region is west of the mountains and includes the Great Appalachian Valley. The region is carbonate rock based and includes Massanutten Mountain. The Cumberland Plateau and the Cumberland Mountains are in the southwest corner of Virginia, south of the Allegheny Plateau. In this region, rivers flow northwest, with a dendritic drainage system, into the Ohio River basin.
The Virginia Seismic Zone has not had a history of regular earthquake activity. Earthquakes are rarely above 4.5 in magnitude, because Virginia is located away from the edges of the North American Plate. The largest earthquake, at an estimated 5.9 magnitude, was in 1897 near Blacksburg. A 5.8 magnitude earthquake struck central Virginia on August 23, 2011, near Mineral. The earthquake was reportedly felt as far away as Toronto, Atlanta and Florida. 35 million years ago, a bolide impacted what is now eastern Virginia. The resulting Chesapeake Bay impact crater may explain what earthquakes and subsidence the region does experience.
Coal mining takes place in the three mountainous regions at 45 distinct coal beds near Mesozoic basins. Over 64 million tons of other non-fuel resources, such as slate, kyanite, sand, or gravel, were also mined in Virginia in 2018. The commonwealth’s carbonate rock is filled with more than 4,000 caves, ten of which are open for tourism, including the popular Luray Caverns and Skyline Caverns.

As promised for those who attended HEAT Recon, this is my very quick and dirty IPB of downtown Alexandria, VA. It was originally meant to serve as a primer on emergency route selection in case of large-scale fire, flood, or other evacuation-inducing event. It could also be used as a rough guide for patrol or PSD route selection. I made slide 09 for that purpose, but also to serve as a survey of possible operational zones if a Katrina-style event happened and citizens were forced to bug in and GTFO on their own after a bit. I left that section out of the version I handed to the Alexandria EOC for obvious reasons. In its current form, it needs updating for recent activities and demographic changes, so if you plan to use it for anything, let’s work on it to make it a presentable product. Feedback is welcome.

Rich (Keith, lol) very good stuff. I liked what you did with the overylay graphics. Made it easy to understand and visualize where the work needed to be done. Granular detail emphasizes that this work needs to be done AO by AO by people who are operating there. Thank you.

Thank you for the post, I am glad you didn’t forget!
This gives me a good start on what I need to be looking into in my own AO.
