There are any number of steep little hills running up to the top of a ridge that runs parallel to Charles Street. The hills on the western side, like Christopher, are consistent, and consistently steep. Smart on the other hand, in spite of what the gradient map might indicate, has a very inconsistent pitch, with a spike up to around 25% right near the top. Fun hill, in any case.
Smart St is located in Rhode Island. It is 304.9 meters long with an average gradient of 10.6% and a maximum gradient of 15.4%. Find similar hills.
