The best-known ruins in Pennsylvania
Ordered by how much has been written about each place. The numbers match the map.
Pennsylvania's ruins lean industrial. The Carrie Blast Furnace Number 6 and 7 stand 3 km from Wilkinsburg, Centre Furnace is 2 km from State College, and the Bradys Bend Iron Furnaces Historical Site sits at 284 meters. Around Easton there are the Lehigh Canal Chain Bridge and the Old Mill (Ruins); Willow Grove has the Langstroth Mill Complex and Bone Hill Mill. In Philadelphia, the President's House is a kilometer from the center.
RLQuest knows 53 named ruins in Pennsylvania, 13 of them with a Wikipedia article, the state's only page for now. Furnaces and mills tend to sit by water, so most of these end a creek-side path. The app logs that path as your quest, confirms the arrival from the route, and adds the valley to your map a tile at a time.
Every dot is a place. The numbers mark the highlights listed below.

RLQuest knows these places too. Which means:
Some of your daily quests lead to a real place near you. The app uses your location to check you were really there.
If you're the first person in RLQuest to complete a quest at a place, it's your first find. The Place Book shows you which kinds of place you're still missing.
Every walk uncovers tiles, each about 350 m across. Over time you can see which corners you know well, and where you've never set foot.
