Bull Moose on  Knik River Road near Palmer, Alaska under the northern lights.     Moose are the largest species in the deer
family with long, slender legs that support a massive body and a short, thick neck and humped shoulders that support a large
head.  The Alaska-Yukon race is the largest of all moose.  Only bulls have antlers and they are the largest of all animal antlers,
over six feet wide and 80 pounds.  Antler is the fastest growing tissue of any mammal, growing a pound and an inch a day in
summer.  They start growing in spring and are shed each winter annually.  Anters are palmate, having main and brown palms in
a butterfly shape.  Fur is generally dark, black to brown or grayish brown, with the lower legs being lighter and their underfur and
long guard hairs provide excellent insulation from the cold.

Moose are the least social species among the deer family, remaining fairly solitary except during the mating season.  They are
not territorial.  Outside of the rutting period, males and females are separated spatially, seasonally, and/or by habitat. Moose are
crepuscular by nature, being most active at sunrise and sunset.  Despite their ungainly appearance, moose are able to run
silently through dense forests.  Maximum speeds have been clocked at 35 mph.  Moose are also strong swimmers, being known
to swim up to 12 miles.  Their daily pattern includes traveling to new feeding sites, avoiding predators, browsing on plants,
standing, and lying down for the rumination of their food.  Moose mainly stay in the same general area, though some populations
seasonally migrate up to 110 miles. Home range size of moose varies between 1.4 to 35 square miles.  During their first year of
life, young moose occupy the same home range as their mother and do not establish their own home range until the age of two.

Moose are herbivores and primarily browse upon the stems and twigs of woody plants in the winter and the leaves and shoots of
deciduous plants in the summer.  Willows are the most preferred forage where available.  In interior Alaska, willows accounted
for 94% of the biomass consumed in the winter.  Food quality depends on twig bite size, fiber, species, and spacing in habitat.  
During winters of deep snow, food may be inaccessible to moose.  They have a difficult time walking in snow depths of greater
than 3 feet.  During summer months, moose often feed on aquatic plants in ponds and lakes.  They can dive to 20 feet in search
of plants.  This food is highly digestable and abundant in many areas.  An adult requires about 44 pounds of food per day to
maintain energy levels for foraging and traveling.

Moose breed in September and October of each year, during a breeding season often referred to as "the rut".  Gestation averages
about 231 days, with cows giving birth to one calf on average and often twins.  Calves are born at an average weight of 36 pounds
and gain approximately 2.2 pounds per day while they are nursing .  Males and females are sexually mature at two years of age,
but full growth potential isn't reached until four or five years of age.  At that age, females are at their reproductive peak and males
have the largest antlers.  Moose are polygamous, and only females take care of their young for a period of one year.  Females
seek secluded sites to give birth to young and remain highly protective until their calves are weaned.  Calves can browse and
follow their mother at three weeks old and are weaned at five months.  They remain with their mother until about one year after
their birth, when the mother's next young is born.

Northern Lights

Also know as the Aurora Borealis, these lights are best viewed in the cold dark winter months in Alaska.   The beautiful blaze of
Northern Lights, or Aurora Borealis, begins when energetic electrically charged particles accelerate along the magnetic field
lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light. The air lights up rather
like what happens in a fluorescent light tube.  The colors reflect gases, the most usual yellow-green color coming from oxygen.
Red coloring is also due to oxygen with a contribution from nitrogen and violet is due to nitrogen. The charged particles originate
from the sun, and it is the “weather” conditions on the sun that decide whether or not we will see the aurora.

The website address will not be printed on your print.  This print is treated with an ultra violent protective coating.  It will be rolled
and inserted into a mailing tube if ordering a glossy paper print, if ordering stretched canvas this print will be boxed.   The print  
will be mailed first class by the U.S. Postal Service and insured.
