[2] Cape Cheerful, the western point at the entrance to Unalaska Bay, is made up of bold, very high headlands, rounded on top, and intersected by deep, grassy valleys.

Ulakhta Head, 900 feet high, the north end of Amaknak Island, is, in clear weather, one of the best landmarks for fixing the position of Unalaska Bay.

Constantine Bay, about 4 miles from Cape Kalekhta, is obstructed by numerous rocky ledges, many of which are only evident from the attached kelp.

The usual anchorage is at the head in 14 to 16 fathoms, muddy bottom, where, even with northerly winds, the force of the sea does not seem to reach home.

At the head of Iliuliuk Bay, behind the village, there is a distinct ravine or break in the mountains, which extends through to the water to the southward.

The portion south-southwestward of Amaknak Island is the long narrow inlet of Captains Bay.

[3] When bound for Unalaska Bay from any part of Bering Sea, it is recommended to shape the course for Cape Cheerful.

Strangers, when in the vicinity and uncertain of the identity of the bay and its landmarks, should endeavor to pick out Ulakhta Head.

Looking into the bay, its flat top breaking off abruptly to sloping sides presents an appearance unlike any other in the vicinity, and shows up well against the background of mountains.

A large cluster of rocks, mostly awash, and usually marked by breakers, extends nearly 200 yards (180 m) to the westward of the south head of Constantine Bay.

Iliuliuk Reef consists of a ledge of rocks, portions of which are always exposed, extending in an east and west direction for 250 yards (230 m).

From the eastern dry rock a ledge, marked by kelp, extends south by east-southeast 150 yards (140 m).
