Cedros Island

[1] Cedros Island is located in Ensenada Municipality, off the west coast of the Mexican state of Baja California, from which it is separated by 100-kilometre-wide (62 mi) Sebastián Vizcaíno Bay.

It is 22 km (14 mi) northwest of Punta Eugenia in Mulegé Municipality - the westernmost point of the state of Baja California Sur mainland.

The Isla de Cedros was named by early Spanish explorers who mistakenly associated the large amounts of redwood and cedar driftwood arriving with the California current for local pines visible on the crest of the island.

It is a "company town," built by the joint Mexican Government and Mitsubishi Corporation to house the workers of the salt-transshipment facility on the island.

There is regularly scheduled air service to the island from Ensenada, departing every Monday and Wednesday, and landing at an airstrip at the south end, adjacent to the "company town," while a 10 km (6 mi) road leads to "Pueblo Cedros".

Open launch rides across the channel between Cedros and the mainland can also be arranged at the Abarrotes Ramales store in Bahia Tortugas, but travellers opting for this transport should be prepared to have a flexible schedule with several extra days in case of inclement weather conditions in the Channel.

Jerusalem is just west of El Morro, but on the western side of the airport, with regularly arranged residential units.

Wayle, 15 buildings on the western side of the southern bight Bahía del Sur, is 3 km (1.9 mi) northeast of San Agustín.

Cedros Island was attractive to humans because of its rich marine environment and its relative abundance of water compared to most of the desert coastline of Baja California.

The early people of Cedros Island fished, gathered shellfish, and hunted seals, sea lions, and seabirds.

In 1539, when the Spanish expedition led by Francisco de Ulloa landed on the island, it encountered several villages with populations at each estimated in the hundreds.

[15] The island consists of a variety of sedimentary, metamorphic, and igneous rocks, including part of an ophiolite complex and high-pressure, low temperature blueschists.

Most of the rocks are of Mesozoic age, though some late Cenozoic strata crop out near the town in the southeastern corner of the island.

The chaparral averages 3 metres (9.8 ft) in height and consists of several woody species including Quercus cedrosensis, the Cedar Island live oak.

[citation needed] Large sea lion colonies are found on the rocks on the west side as well as the anchorage on the north end.

This would be due to the fact that Cedros is on the continental shelf close to the coast and, at least temporarily, it was connected to the mainland during the last ice age when sea levels were lower than today.

Then, and as a consequence of this, there are native Cedros herbivores, such as Cedros Island mule deer which on one hand compete with the goat population for food and presumably have kept it from increasing beyond carrying capacity, and on the other hand forced the native plants to keep their defenses against herbivores, unlike plants on islands without megaherbivores, which tend to lack those defenses.
