The Laguna Alchichicha maar is filled by the largest lake in the Serdán-Oriental basin. The rim of the basaltic to basaltic-andesitic maar varies in height and is highest on the western side. The western crater wall exposes a scoria cone that was partially destroyed by the maar-forming eruption. White tufa deposits line the shore of the lake.
