This is an 8.8 mile with 75 ft elevation out and back hike on the Potomac Heritage Trail in Loudoun County. On this hike we'll experience scenic Goose Creek as it flows into the expanse of the Potomac. There is also a lot of history as we hike along the ruins of the Goose Creek Canal ( see the background information below) and Selden Island which is privately owned and is known for it's prehistoric archaeological sites dating back to 1000BC. We will begin at Riverpoint Drive trailhead (Porta Potty is available) and follow Goose Creek and then the Potomac to our turnaround at Bles Park where there are restrooms. **Background History**: In 1849, construction began on a system of locks and dams to render the Goose Creek navigable up to three large mills in the Loudoun Valley. By 1845, the [Goose Creek and Little River Navigation Company](https://en.wikipedia.org/w/index.php?title=Goose_Creek_and_Little_River_Navigation_Company&action=edit&redlink=1) canal system had been completed on Goose Creek to Ball's (Evergreen) Mill, 12 miles (19 km) upstream from the mouth. Though the lower portion of the canal saw significant usage, only one boat was ever known to have traveled the whole stretch, and by 1857 the canal was put out of business by the completion of the [Alexandria, Loudoun and Hampshire Railroad](https://en.wikipedia.org/wiki/Washington_and_Old_Dominion_Railroad) to Leesburg. Most of the locks and dams were destroyed by the [Union Army](https://en.wikipedia.org/wiki/Union_Army) during the [Civil War](https://en.wikipedia.org/wiki/American_Civil_War). We hike at a pace of \~ 2.5 mph while moving. You must have experience with hikes of this length and elevation gain. Meet at the Riverpoint Drive Trailhead at 8:45am for sign-in. Restroom (Porta Potty) is available at the Trailhead Dogs are welcome on this hike in accordance with the NVHC Dog Policy.

A Pathfinder Society Scenario designed for 1st- through 4th-level characters. Hellknight forces have forcibly taken over Citadel Altaerein, the abandoned Hellknight citadel on the edge of Breachill, a small town in Isger, while also leading a reign of terror on the innocent civilians and the leadership alike. The Eagle Knights of Andoran have called upon the Pathfinder Society for backup while they handle the citadel, requesting that they rescue the civilians and prevent any unneeded harm. While the Pathfinders are moving throughout the town, they learn of a secret way into the citadel, and though it's not without its dangers and threats, they could learn *so much* from the enemy... Written by Matt Duval. **Scenario tags**: Metaplot (Battle's Spark), Repeatable
