Fossil Bike Tour in the District

If you’re looking for a unique local bike tour in Washington, DC, here’s an idea.

Christopher Barr developed a terrific list of locations with accessible fossils embedded in Washington’s architecture at

So I put together this map, which presents the locations in an order that can be followed for an educational afternoon ride around downtown, together with notes on the era of the fossils and links to the web pages describing them.

You can take your bike on Metro to Columbia Heights and start out from there, then reboard after riding at Smithsonian or Capital South.
