Description:

Denali National Park
This winding road goes to Wonder Lake, and a little beyond.  It is 92 miles one way.  I drove it in the fall when winning a lottery ticket.  You
can enjoy this road in the summer by bus many of which are available at the park entrance. To get to the entrance of Deanli National Park
from Anchorage, take Alas. 1 (Glenn Hwy.) 35 miles north to Alas. 3 (George Parks Hwy.). Go north 205 miles.
Also known as Mount McKinley, Denali is Denali is six million acres of wild land, bisected by one ribbon of road.  Denali, the "High One,"
is North America's tallest peak, 20,320 feet and is the name Athabascan native people gave the massive peak that crowns the 600-mile-
long Alaska Range.  There are 39 species of mammals, 169 species of birds, 14 species of fish, and one species of amphibian known
in Denali. There are no reptiles recorded in Denali.  

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.


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.
