Can you believe that Beavers, an important keystone species in North America, live in the city of Baltimore? They do. Join William (Bill) Curtis to look for beaver activity in the Herring Run!

Not only will Bill show how to read the signs of beaver activity, but he will also talk about the important role that beavers have in creating the American landscape as we enjoy it today, and how other species (including us humans!) depend on their work.  Hopefully we will be able to see a beaver or two! All ages are welcome to join us and we really encourage our young naturalists to join us!

Difficulty: Easy-moderate. Most of the trail is level and paved. There is one grassy hill we have to negotiate. The route is not wheelchair accessible. Easy for kids. Total walking distance will be about 1.2 miles.

What to wear: PREPARE FOR THE COLD!!! Dress in warm layers with non-cotton articles of clothing, wear gloves, mittens, hats, scarves, etc. And don’t forget good walking shoes/boots.

What to bring: Water, and a good sense of humor!

Location: We will meet at the top of the Eastwood Sledding Hill, 3600 block of Eastwood Drive.

As always this time of year, snow is a possibility! Please check back on Meetup or our Facebook page in the case of cancellation or postponement if snow is a possibility. We will try to make the call the day before at the latest.



Bill, like most of the other people leading NHSM, is a volunteer, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible.  Please consider donating or becoming a member of the Natural History Society of Maryland and visit for more information.
