Triple-boundary in Brazil: Goiás, Minas Gerais and Bahia
The terrain here lies at the triple-boundary between three of Brazil’s states: Goiás (left), Minas Gerais (bottom right) and Bahia (upper right).
The Federal District (Distrito Federal) of Brasilia is visible as a tan area left of the center. The city of Goiânia, in the state of Goiás, appears as another tan area southwest of Brasilia.
Goiás lies wholly within the Brazilian Highlands, which are located in the center of the country. It occupies a large plateau with a tropical climate.
The state is covered with a woodland savanna known in Brazil as campo cerrado, although there are still tropical forests along the rivers. This cerrado has been seriously diminished in recent years due to cattle raising and soybean farming with great loss of animal life and forest cover.
The vegetation of Bahia, on the other hand, is Atlantic Forest, although deforestation has been causing it to diminish.
The state is crossed from north to south by a mountain chain, Chapada Diamantina (also known as Serra do Espinhaço and Borborema), which divides it in two clearly distinct geographical zones. To the east, the soil is fertile and, despite high temperatures, rainy seasons are regular. The predominant vegetation in the west is “cerrado”.
Finally, in the areas of Minas Gerais visible here, the predominant vegetation to the west is “campo cerrado”, while the south is hilly, green, and notably cooler than the rest of the state.
The state is also crossed by the river São Francisco, in the upper right quadrant, tan from sediments. It is the most important river in the Brazilian northeast because it is a permanent river, which continuously supplies water to this arid region when many other smaller rivers dry out.
