La Perouse Bay
La Perouse Bay or Keoneʻoʻio Bay is located south of the town of Wailea, Hawaii at the end of Makena Alanui Road (State Highway 31) at 20°35′54″N 156°25′12″W / 20.59833°N 156.42000°WCoordinates: 20°35′54″N 156°25′12″W / 20.59833°N 156.42000°W. The bay's Hawaiian name is Keoneʻoʻio. It was later named for the French explorer Captain Jean-François de Galaup, comte de La Pérouse. In 1786, La Pérouse surveyed and mapped the prominent embayment near the southern cape of Maui opposite the island of Kahoʻolawe. The bay is the site of Maui's most recent volcanic activity. The rounded peninsula that dominates the northern half of the bay and extends up the coast a short distance was formed about 900,000 years ago by an eruption of basaltic lava that originated in the southernmost landward expression of the Haleakalā Southwest Rift Zone. A small string of cinder cones extending inland to the northeast marks the axis of the rift zone.
