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!
