Raa Atoll

Raa Atoll (also known as Northern Maalhosmadulu Atoll or Maalhosmadulu Uthuruburi) is an administrative division from the Maldives. The capital is Ungoofaaru. It includes Northern Maalhosmadulu Atoll proper and the island of Alifushi.

1. Alifushi and Etthingili (Powell Islands in the Admiralty Chart) stand on a detached reef of their own with very deep waters (no sounding) between this faru and the northern end of the main atoll.

2. Northern Maalhosmadulu Atoll is 35 miles (56 km) in length from N to S, and 15 miles (24 km) across at its broadest part. Its western fringe is composed of a series of round or oval reefs (farus) irregularly placed (a feature peculiar to all the larger Northern Atolls). The centre is heavily dotted with coral patches (giri), some submerged and some awash. The concentration of giri is especially dense towards its SW quarter, close to Kandholhudhu Island (where there is the place most crowded with small reefs and shoals in the whole Maldives), but its narrower northern end is quite clear of reefs. The general depths of the lagoon are from 23 to 27 fathoms (138 to 162 ft; 42 to 49 m).
