Dwarf Fireweed
Dwarf Fireweed or River Beauty willow herb, scientifically known as the Chamerion latifolium. This whole herb is eatable, from the pink flowers with long capsules, thin green stems to the long oval green leaves they flower June to August. Natives use it for many things, such as tea in salads and just eaten raw. It has pretty much the same taste as spinach would. You can see this plant grow in clumps along river banks, gravel sandy areas and sometimes in alpine areas without wetlands in Alaska , Canada, to Colorado also California.

Mourning Cloak
Mourning Cloak or Nymphalis antiopa is a butterfly with no similar species. They feed on sap, rotting fruits and flower nectars, they live in open areas, the woods and small water areas. They mate in the spring and the eggs are laid on twigs of their plant host, then the adults die. the caterpillars hatch and eat the host plant, when they are ready to turn to butterflies they cocoon and when they emerge with a wingspan of 2 1/4 to 4 inches. They then fly south for the fall and then the pattern repeats again. They can be found anywhere between the Tundra and central Mexico.

Bog Rosemary
BOG ROSEMARY
The Bog Rosemary, Scientifically known as Andromeda polifolia. Now this is not the kind of rosemary you cook with, because every part of this evergreen shrub is not edible. Bog Rosemary is in Greenland to Alaska, Canada, Idaho and all the way to New Jersey. They grow in peat bogs because the roots can stay cool and like full to partial sun with some shade. Bog Rosemary has a thin stem that grows to be about 20 cm tall and has thin long spiky dark green leaves, which turn purplish in the winter. The bell like white-pinkish flower blooms in spring.
Not many animals eat the bog Rosemary, But moose on the Kenai peninsula have been known to munch on this shrub.

They can be found throughout the world and all over north america and found all year round as long as the water isn't frozen in small ponds, marshes and small pools by rivers. They feed on both living and dead insects like dragonflies, mosquitos, and various others such as beetles and butterflies, also mosquito larvae. Water Striders are between 3 to 16 mm or 1/2 inch in size and has 6 legs, the front are used to grab prey the back 4 are used to push around on the water allowing them to move very quickly. They are able to glide over water because they are so light and have water proof hairs on their legs.

It was an cool trail being on the side of the hill like that like the whole town was. What a view too, seeing that Karst and hearing the glacier cracking was amazing. It was pretty to see all the other plants that grew there and see the difference between there and here.

At first i didnt expect to find anything in the water but it turned out there was a lot in there. Like the frog Carl caught and all the water striders on the surface and it was all fine until i saw the giant spider and then i had to get back in the car.

Haliaeetus leucocephalus
The magnificent bald eagle is a bird of the North American and Canadian territories. The bald eagle visits the Prince William Sound to breed and fledge offspring. They winter in the southern and central parts of the United States and spend their summers in Alaska and Canada. Bald eagles favorite meal item is fish and prefer habits nears lakes, rivers, and sea coasts where their prey is plentiful. They are a bird of prey that can grow to be over three-feet tall with a wingspan of eight-feet in length. Mature adults are easily spotted by people because of their white head and tail, however, juveniles are completely brown and often mistaken for another type of eagle. Bald eagles take up to five years to become sexually mature and return to their birthplace to reproduce. These birds can live 20 or more years in the wild and their life expectancy doubles in captivity. Bald eagles, on average, lay two eggs but it is rare for both offspring to survive to become a mature adult. Bald eagle relationshhips are similar to humans in many ways. They are monogamous animals when partnered. If one mate dies the other eagle will find a new mate; unlike another Alaskan bird the tundra swan that will not find another mate after theirs dies. Also, if the mating pair of eagles are not successful with reproduction they will break up and find other mates to try and reproduce with. Many Native American cultures saw the bald eagle as a guide between the physical and spirit world. Acting as messengers between the gods and the tribes.
