DESCRIPTION OF NUNIVAK ISLAND
Nunivak Island, where Harrold’s most important
work was done, had not previously been visited by an ornithologist. It lies
in Bering Sea, between the mouths of the Yukon and Kuskokwim rivers and about
forty miles off-shore, much nearer to the mainland than to any
other of the islands of Bering Sea. It is one of the larger islands, about
seventy miles long.
He landed at Nash Harbor, “situated on
the northwestern side of the island, at the mouth of a stream
of considerable size, which widens out into a small lake only a
few yards back from the sea-shore.” Near the lake was a native
village, and in this vicinity Harrold made his headquarters. His description
of the surroundings reads as follows:
“Nunivak Island, situated about
halfway between Nome and Unalaska, consists mainly of rolling tundra,
practically treeless except for very stunted willow and a pigmy birch,
which attains an average height of about six inches. In the interior
there are several more or less prominent hills, the highest of which
is said to have an altitude of about 600 feet. The shore line at the
extreme western end of the island is rugged and precipitous, the cliffs
rising perpendicularly to a height of from 100 to 200 feet. Here sea
birds, particularly murres, nest in numbers, the natives paying annual
visits to the nesting grounds to secure skins of puffins, murres and
others for clothing. Only a few miles from Cape Mohican, the western
extremity, the cliffs become less precipitous, and evidence of rapid
erosion is noticeable along both coasts.
Eastward along the north shore
the mossy tundra slopes gradually down to the water’s edge, with
sandy beaches in the bays. In the lower areas of the interior there
are numerous lakes and sloughs, while toward the western part of the
island outcroppings of rock are frequent in the hills, forming the
habitat of the few Rock Ptarmigan observed. In the draws, or sheltered
coulees, the combination of ‘niggerheads’ and a tangled
mass of stunted willows, with long grass covering the pitfalls between,
makes travel on foot difficult.
The country in the vicinity of Cape
Etolin (the northeastern part) differs strikingly from other sections
visited. There, near the mouth of the Mekokayak River, there are several
extensive tidal mud-flats, the largest about two miles long and one
mile wide. Exposed at low tide, these form a great attraction to geese
and waders. A rather surprising feature of this locality is the considerable
area of sand-dune country, mostly overgrown with tall ‘rye grass’ (Elymus
mollis). This grass, the seeds of which constitute the main food
supply of the snow buntings in the fall, is woven into baskets, mats,
and even socks, by the Eskimos.
“There was a marked scarcity
of nesting ducks and geese in the interior, although the wide marshy
valleys appear to offer an ideal breeding ground. This scarcity may
be attributed to several causes, chief of which is probably persistent
hunting by the natives, particularly of the geese. Loons, chiefly Red-throated,
are common and may have some effect on nesting ducks by driving them
from the sloughs. Large gulls are often seen hawking over the tundra
lakes and no doubt take toll of nesting water fowl.
“In the fall
the crowberry (Empetrum nigrum), abundant everywhere, is
added to the diet of a number of birds, including cranes, geese,
Pacific Eider, gulls, god-wits and snow buntings, the faces of many
individuals being stained by the purple juices.” |
