Site code BKN given by Corpus of Maya Hieroglyphic Inscriptions (1999:187-189; 2012; 2016); cited by Riese (2004), Mathews (2005). The site is listed by the Corpus of Maya Hieroglyphic Inscriptions Project as a location in which inscriptions were discovered, yet the Bonn Project does not have any published or oral reports on it. This information remains to be verified, however, Pollock describes broken sculptured columns (cited in Mayer 1984:44).
The location is unknown, Pollock places it around 7 km east of Bohola and southwest of Acanmul (Pollock 1980:533;Muller 1960:22).
