The headwaters of granodioritic Río Blanco are unusually flat before cascading
steeply down the side of the batholith and leveling out along the alluvial coastal plain. The inflection point where the stream sharply steepens occurs at the edge of
a non-glacial hanging valley.
Headwaters are within El Yunque National Forest, while the coastal plain has urban areas and major roads.
