WAncón de Sardinas is a bay in the Pacific Ocean, located on the border between Colombia, which is to the north, and Ecuador, which is to the south. In this place begins the maritime delimitation of the border between Colombia and Ecuador, which consists of a single treaty signed on August 23, 1975 and, from the intersection of the extension of the land border and the confluence of the territorial areas of both countries, a midpoint is marked in the bay; From here to the Mataje River, which flows into it, a line is drawn that terminates the boundary.
WCotacachi Cayapas Reserve contains 752,235 acres (3,044 km2) of land and is located in the Imbabura and Esmeraldas provinces of Ecuador 87 miles (140 km) from Quito. Elevations in the reserve range from about 300 metres (980 ft) in the east to Cotacachi Volcano which reaches an elevation of 4,944 metres (16,220 ft) in the southwest. This nature reserve is partly rainforest. The park is mix of many biological zones but, the Andean and Sub-tropical zones are most common. The symbol of the reserve is a condor.

WThe Esmeraldas Formation is an Early Pliocene geologic formation of the Borbón Basin in northwestern Ecuador.
WThe Onzole Formation is an Early Pliocene geologic formation in the Borbón Basin of northwestern Ecuador. The formation consists of a shallow marine sandstone member containing many fish fossils, among which megalodon, and a deep water member comprising tuffaceous shales and mudstones containing gastropods, bivalves and scaphopods.
WThe Viche Formation is a Langhian geologic formation of the Borbón Basin in northwestern Ecuador. The formation underlies the Angostura Formation. Fossils of Ziphiidae indet. have been found in the formation.
WThe Malpelo Plate is a small tectonic plate (microplate) located off the coasts west of Ecuador and Colombia. It is the 57th plate to be identified. It is named after Malpelo Island, the only emerged part of the plate. It is bounded on the west by the Cocos Plate, on the south by the Nazca Plate, on the east by the North Andes Plate, and on the north by the Coiba Plate, separated by the Coiba Transform Fault (CTF). This microplate was previously assumed to be part of the Nazca Plate. The Malpelo Plate borders three major faults of Pacific Colombia, the north to south striking Bahía Solano Fault in the north and the Naya-Micay and Remolino-El Charco Faults in the south.
