Far away ports (2) Landscape and climate

The landscape of these four cities is marked by the irregular coastline, elevation, geology and vegetation.

Brest sits on top of a coastal cliff some 40 m high which overlooks the bay, with the Penfeld valley (the initial port) as its western limit. There are just a few zones around with heights over 60 m; the coast is marked by cliffs, but not by mountains or characteristic hill profiles. Ravines create valleys that are significant in this landscape.

Duluth is the meeting point for the northern Lake Superior hills and the plains to the south, as well along the Saint Louis river estuary. The city site is on a complex land, with steep slopes of volcanic genesis, something that has not helped street and building construction. The elevation difference from lakeshore to the highest points some 2 km inland is close to 200 m, and has contributed to a rich scenic context, attracting tourists since the 1880s. Ravins flowing into the lake have become natural limits between city zones. A sandbar at the mouth of the Saint Louis river estuary protects the harbour. The city has colonized the lakeshores and the estuary, as well as the hinterland.

La Coruña is on the western edge of the Artabrian gulf, a set of bights that reaches Ferrol to the North. It is a series of limited height hills, but on the areas neighboring the open seas, as on Monte de San Pedro. The city appeared on the eastern point of a peninsula united to the mainland by a narrow sandbar; during the XXth century the city has overflowed the plain areas to go uphill to the south and on the northern parts of the original peninsula. There is an inlet on each side of the peninsula, and the harbour is on the eastern one.

Puerto Montt municipality has some areas to the east with elevations well over 1.000 m, but the city itself is on much lower ground. The port sits on a rather benign slope, that is interrupted by a relevant cliff that gets up to the 100 m contour line. This allows for scenic vistas over the Seno de Roncagua, the large bay which extends to the south the Chilean central valley and separates the shores of the Andes from Chiloé Island. The harbour is on the channel between the mainland and Tenglo island.

The climate of these four cities is quite similar during their summers (Puerto Montt is on the southern hemisphere) ; you hardly get beyond 25 ºC, and rain is rather high. Only Duluth sees snow and freezing cold for several weeks on a row, so it has created a Skyways network.
