This area has been geographically so much altered, that it is hardly possible to find some stretches of this canal.
The ancient name of the canal will remain disputed. Sometimes a temple was named after the canal in its vicinity or opposite. On PBR's map we find Wat Pa Mok (วัดป่ามอก) and Wat Thong Pak Mo (วัดทองปากหม้อ); on the 19th century map there is Wat Thong Pa Mo Noi (วัดทองป่าม่นอย) and Wat Thong Pa Mo Yai (วัดทองป่าม่ใหญ). On a FAD map (1974) the canal is named คลองป่าม่อ. So we find มอ, ม่อ and หม้อ.
For the word ม่อ I could not find an explanation. The word มอ means either a kind of boat, a small mound or a bull. หม้อ could be translated as a pot. In this case I chose for the word มอ and to translate it as a small mound.
