Unalaska. It is a small town (geographic location:
53 ° 53′20 ″ N 166 ° 31′38 ″ W) on Unalaska Island and the neighboring
island of Amaknak in the Aleutian Islands (Alaska). The city has a total
area of 549.9 km². The number of residents registered in 2005 was 4,347.
Almost all the port facilities are on Amaknak Island, better known as
Dutch Harbor or simply Dutch as it is called by the crab fishermen of
the Bering Sea. The port is connected to Unalaska by a bridge. The name
"Unalaska" is probably a derivation of the Russian name "Ounalashka".
The island was discovered by Vitus Bering in 1741. In 1759 the
Russians established themselves making a permanent settlement, but four
years later it was destroyed by the Aleuts, along with four merchant
ships. The massacre claimed the lives of 162 Russian settlers. The
survivors managed to hold their position until 1764, when they were
rescued by the Russians. This event provoked very bloody reprisals
against the natives, which cost the lives of about 5,000 Aleuts.
The expedition of Esteban José Martínez and Gonzalo López de Haro
of 1778 explored the coast of Alaska to Unalaska Island, marking the
western end of what the Spanish explored in the region. In Moscow on May
31, 1988, President Ronald Reagan mentioned the meeting of Americans and
Russians on this island in the 19th century as an example of
long-standing friendship between the United States and Russia.
The 8 as December as 2004 A Malaysian cargo ship, the Selendang Ayu,
ran aground on Unalaska Island, causing a large oil spill The Unalaska
and Amaknak Islands had 24 settlements with more than 1,000 Aleutians in
1759. In 1768, Unalaska became in a Russian trading port for the sea
industry. In 1825, the Russian Orthodox Church built a church in
Unalaska. The priest, Ivan Veniaminov, composed the first Aleutian
writing system with local help, and translated the holy scriptures into
that language. During this time, (between 1830 and 1840), only 200 to
400 Aleuts lived in Unalaska. On June 3, 1942, during World War II,
Unalaska was attacked by the Japanese. Most of the island's native
residents were sent to Southeast Alaska during the war.
The island is located to the west of Akutan Island, from which it is
separated by the Akutan Pass, and to the east of Umnak Island, from
which it is separated by the Umnak Pass.
Unalaska is the second largest island in the Fox group of the
Aleutian Islands. Unalaska's coastline is remarkably different in
appearance than that of other large Aleutian islands, with countless
inlets and peninsulas. The irregular coastline is broken by three long,
deep bays: the Beaver Inlet, Unalaska Bay and the Bay of Makushin ;
there are many more bays and smaller coves. Unalaska's terrain is rugged
and mountainous, and for most of the year the highest peaks are covered
with snow.2 Unalaska's name is of Aleutian origin and there are several
theories about its origin, the most likely being the name comes from a
deformation of the Russian word Unalashka.

A wet day is a day with at least 1 millimeter of liquid or
liquid-equivalent precipitation. The chance of wet days in Unalaska
varies throughout the year. The wetter season lasts for 5.8 months, from
September 1 to February 24, with a greater than 36% chance that a given

To show variation over a month and not just monthly totals, we show
accumulated rainfall over a 31-day rolling period centered around each
day of the year. Unalaska has a considerable variation of monthly
rainfall by season. Rain falls throughout the year in Unalaska. Most of
the rain falls during the 31 days centered around December 9, with an
average total accumulation of 101 millimeters. The approximate date with
the least amount of rain is April 25, with an average total accumulation
of 44 millimeters.
Snow is reported in liquid equivalent terms. The actual depth of a
new snowfall is generally 5 to 10 times the equivalent amount of liquid,
assuming the ground is frozen. The coldest and driest snow tends to be
towards the upper end of that range and the less cold and
wetter snow towards the lower end. As with rain, we consider accumulated
snow during a 31-day rolling period centered around each day of the
year. The liquid equivalent snow accumulation in Unalaska varies
The snowy period of the year lasts for 4.7 months, from November 21
to April 11, with a liquid equivalent snowfall of at least 3

We base the comfort level of humidity on the dew point, as this
determines whether sweat will evaporate from the skin, thereby cooling
the body. When the dew points are lower it feels drier and when they are
high it feels more humid. Unlike the temperature, which generally varies
considerably between night and day, the dew point tends to change more
slowly, so even though the temperature drops at night, on a humid day
the night is generally humid. Unalaska's perceived humidity level,
measured by the percentage of time that the humidity comfort level is
muggy, oppressive, or unbearable, does not vary significantly throughout
the year, and remains virtually constant at 0%.
This section deals with the hourly average wind vector of the wide
area (speed and direction) at 10 meters above the ground. The wind from
a certain location is highly dependent on the local topography and other
factors; and the instantaneous wind speed and direction vary more widely
than the hourly averages. The average hourly wind speed in Unalaska has
extreme seasonal variations throughout the year. The windier part of the
year lasts for 7.6 months, from September 13 to May 2., with average

Unalaska Harbor is the main port and base of the Bering Sea crab
fishing industry. It has been the largest fishing port in the United
States in terms of the volume of shellfish caught, from 1981 to 2000,
and in terms of value per catch. However, since 2000, the port of New
Beford, Massachusetts, has surpassed it in that category.
A pilot project in the port of Unalaska is producing biodiesel from
fish oil from the local fishing industry in conjunction with the
University of Fairbanks Alaska. The economic use of fish oil is rare,
and Alaskan communities are highly dependent on diesel power generation.
Local factories generate 3.5 million tons of fish oil annually.
