Description:  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 the
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.
