Alaska Sunday XXIII

Trip Log - Part VI

July 3 - July 6

The sixth installment of the actual trip log and mileage of 'The Drive from Texas to Alaska and Back'.

As mentioned previously, this log does not contain too much commentary. It is mainly sequential locations, dates, mileage traveled, photographs showing the trip progress, and how the landscape changed. The Alaska Trip Log is divided into short intervals (parts) and I am posting it on consecutive Sundays. Past and future posts of Alaska Sunday (apart from the trip log) will have more detailed information, and more photos of each specific area.

Click on the links for more photographs and detailed descriptions of this part of the trip.

Last week was a temp post. Today we will continue with mileage from Fairbanks to Denali and on to Anchorage.

Be sure to click on the photographs for full screen views.

And so, on with the trip.


7/3 Fairbanks, Alaska to Denali, AK 156 mi


7/4 Denali and Healy area 65 miles

Red Squirrel - Western type

Snowshoe Hare
Summer coat (He still has white feet)

Winter food for the Animals
Lots of mosses and lichens in the shelter of the trees

7/5 Denali Highway and back to camp 220 miles

We did not drive all of the Denali Highway. Too many stops.
It was mostly cloudy all day. We did get one break in the clouds to photograph the following panorama even though most of the landscape was in shadows.

7/5 Denali RV Park to Anchorage 210 miles

Sunset after camp was set up
about 1 AM

Next week we will be around the Anchorage area.

Mileage for this section of the log ...........651 mi
Mileage before 7/3 ................................8944 mi

Total miles for the trip to date ...............9595 mi

We are closing in on 10,000 miles

Comments are appreciated.
Let me know if you are keeping up with the trip,
or are just a onetime visitor.

Orange Lichen

Lichens are Odd Fellows

Orange Lichen (Teloschistes exilis)

A couple of really nice lichens. . I have photographed a lot of them, and now I guess it's time to invest in Brodo's book - "Lichens of North America". See here at Amazon.com.

Update: Whoohooo! the book is Ordered. Second Update: It's here, all 8 1/2 lbs.
According to Irwin Brodo, the two species are Teleoschistes and Parmotrema.

Lichens are symbiotic associations of a fungus (the mycobiont) with a photosynthetic partner (the photobiont also known as the phycobiont) that can produce food for the lichen from sunlight. The photobiont is usually either green alga or cyanobacterium. A few lichens are known to contain yellow-green algae or, in one case, a brown alga. Some lichens contain both green algae and cyanobacteria as photobionts; in these cases, the cyanobacteria symbiont component may specialize in fixing atmospheric nitrogen for metabolic use.

In the natural environment, lichen "provides" the alga with water and minerals that the fungus absorbs from whatever the lichen is growing on, its substrate. As for the alga, it uses the minerals and water to make food for the fungus and itself. Algal and fungal components of some lichens have been cultured separately under laboratory conditions, but in the natural environment of a lichen, neither can grow and reproduce without a symbiotic partner. Indeed, although strains of cyanobacteria found in various cyanolichens are often closely related to one another, they differ from the most closely related free-living strains. The lichen association is a close symbiosis: It extends the ecological range of both partners and is obligatory for their growth and reproduction in natural environoments. Propagules ("diaspores") typically contain cells from both partners, although the fungal components of so-called "fringe species" rely instead on algal cells dispersed by the "core species".
