People generally see the island as they sail around the northern part of Isabela on the way to Tower Island.[citation needed] Marchena is Tower Island's nearest neighbor, about 45 miles due west.[citation needed]
Like many of the Galápagos volcanos, Marchena has a caldera.[citation needed] Marchena's caldera is roughly elliptical and measures 7 by 6 kilometres (4 by 4 miles), within the range of caldera sizes of the large western volcanoes.[citation needed] Marchena's caldera is unusual, however, in that it has been almost completely filled with young lavas, some of which has spilled over and down the sides.[citation needed] The oldest lava pools go back 500,000 years.[citation needed]
