coast generally consists of rocky bluffs with detached rocks fronting some of them. Two high and prominent islets are within of the southwestern end of the island, separated from one another by a gap called Tuna Alley: Islote Afuera (Outer Islet, also Islote Zapato), , , the most distant, steep with almost vertical walls above and below water Islote Adentro (Inner Islet, also El Toro), , , with two smaller islets nearby: Church Rock Roca del Skip Elsewhere, the other islets are very small and close to the shore, all less than away: Islote Negro, , , to the southwest Roca Hundida, , , to the southwest Islote Bernal, , , to the southwest Palto Muerto, , , north of Islote Bernal unnamed islet, , , north of Islote Bernal Steamboat Rock, , to the west Roca Elefante, , to the northwest (the westernmost) Roca Elefante is the westernmost point in both Mexico and Latin America. Climate The island has two major climate zones: a very arid, warm climate between elevation, with mean monthly temperature between and an arid, temperate climate above elevation. Most precipitation occurs over the winter months with a strong influence of northwestern winds and cyclones. Rainfall averages near sea level at the south end, but appears to be much more at the high north end. An estimate for the rainfall in the northern highlands is possible by way of taking Pinus radiata as an indicator, which is native to that area of the island. In other places where Pinus radiata is native, it grows best with about of rainfall but under some conditions can survive with as little as half that much. The effective moisture is much greater because of fog drip. Ecology Guadalupe Island was a major destination for Russian and American fur hunters seeking the Guadalupe fur seal (Arctocephalus townsendi) in the 18th and 19th centuries. Captain Auguste Duhaut-Cilly reported in 1827 that a Sandwich Islands (Hawaiian Islands) brig "had spent several months there and collected three thousand sealskins". The northern elephant seal (Mirounga angustirostris) was also ruthlessly hunted for the oil in its blubber. Northern elephant seals were thought to be extinct by 1884 until a remnant population of eight individuals was discovered on Guadalupe Island in 1892 by a Smithsonian expedition, which promptly killed several of them for their collections. The northern elephant seals managed to survive, and were finally protected by
