A southern forest whose name translates roughly as "bag of soils"—a reference to the unusual variety of ground conditions within its boundaries. Sandy patches border clay deposits border rocky outcrops, sometimes within the same clearing. Botanists find the forest fascinating; everyone else finds it annoying.
The varied soil produces varied flora, including several medicinal plants found nowhere else in the region. Herbalists from across Central Aboyinzu make pilgrimages to Bolsaña P'Suelos, though they often hire local guides—the forest's patchwork terrain makes navigation difficult.
