Cabo Orange (4°28'N., 51°29'W.), the N extremity of the Brazilian coast, is low, but its salient position is easily iden tified from E as the hills on the W side of the Fleuve Oyapock are visible behind it. The vegetation covering the N part of the cape is higher than at its S part and can be seen from a distance of about 12 miles. The cape should not be approached within a distance of 11 miles. The cape is marked by a light. The coast from Cabo Orange to Cabo Norte, about 195 miles to the SSE, is low and covered with tropical vegetation which can be seen for about 12 miles. Several rivers flow into the sea along this part of the coast. The action of these river, combined with the Amazon River, cause frequent changes in the coast line. The silt carried out by these rivers forms soft mud flats which extend a considerable distance offshore in places. Man groves spread rapidly during the dry seas over the mud flats but are destroyed during the rainy season.
