Furo Santa Maria

Furo Santa Maria lies among the waterways of the Pará estuary on the southern side of Marajó. A furo is a narrow channel through the islands and flooded forests of the Amazon mouth. River water and tides meet in this low-lying country, where the Pará estuary receives flows passing through the channels west of Marajó. Islands and wooded banks divide the water into many passages before it reaches the open bay.
