Pattiw High Sea

Pattiw, or the Western Islands, is the westernmost part of Chuuk in the Caroline Islands. Its three islands or atolls, Houk, Poluwat and Pollap, cover only about seven square kilometres together, but they stand on wide reef banks. Poluwat lies at the northwest corner of the Uranie Bank of about 322 square kilometres, and Houk marks the south-eastern point of the Manila Reef of about 332 square kilometres.
