Northwest Branch is one of the Mid Atlantic’s hidden bouldering gems. Located just north of the DC beltway in Silver Spring, MD, this urban crag experiences a high volume of visitors and more than it’s fair share of litter and other environmental impact. MAC has been hosting Adopt a Crags here for more than five years, and is committed to preserving this resource for generations of climbers to come. Please register below!

What We’ll be Doing:

We’re finalizing the details with the land manager, but our current scope includes trail work as well as graffiti removal.

What to Bring:

Graffiti removal can be a messy affair.  Some people cite skin irritation when the removal product comes in contact with their skin; some don’t.  Because of this, we recommend long sleeves, long pants, and close toed shoes. We will be providing gloves and eye protection.

In addition, we recommend bringing water and a snack.
