This is a continuation just some of the things I saw on the flight from Fairbanks that gives a personal meaning to topics we cover in class.

What Formed This Lake?
IPB Image
This was a large frozen lake seen about 36 minutes into the Fairbanks-Seattle flight. It seems so unusually large and rounder compared to other near-by lakes that I'm very curious about what may have formed it. It also appears to be at a relatively high altitude, not like at the bottom of a deep valley.

A Lot to Be Seen in this Picture

In the center of this picture are some small, rounded lakes. I believe these are kettle lakes. What causes kettle lakes? Does this look like an area where kettle lakes would be found?
Also notes the cliff-like features in the bottom third of the photo. These look like very steep cliffs or ridges. Thirty eight minutes into the flight, we might be getting closer to the more tectonically active area of Alaska. Could these be localized ridges are scarps caused by faults?


Lake or Glacier?
IPB Image
Repeated features like the one shown towards the top of this picture had me asking the most questions trying to figure out what I was seeing. This is definitely some solid ice, and it is in kind of a valley, but it doesn't have the flow features that glaciers usually have. I think this is just a frozen lake, but what do you think?

Another Large Lake?

Another one of those features that kept me guessing

Mountains and Valleys

The terrain seems to be getting even more rugged and a greater range of elevation (relief). This is about 46 minutes into the flight from Fairbanks heading south/southwest. Is this approaching the Chugach Range?

Perplexed Again
IPB Image
It may be my imagination, but there seems to be at least a few houses in the valley towards the top of the picture. If so, does the frozen lake (?) ever impact them? Again, it almost seems as though this frozen feature may be a glacier, but there seems to be melting along the edges, and a lack of medial moraines and other flow characteristics of glaciers. The narrow valley indicates flow of ice or water though, so does this ice (or ice futher up the mountains) ever melt and run through this valley?

I Can't Take it Anymore!
IPB Image
Now this one REALLY looks like a river or glacier where two "tributaries" meet. However, it again seems to have an end, and evidence of ice movement seems to be absent, so is this just a lake?

Cracks in the Ice
IPB Image
This was a closer shot of one of the lakes (?) shown in the "I can't take it anymore" picture. The pattern of these cracks seem to indicate ice breaking up like on a lake or a river, rather than cracks due to flow of ice in a glacier. Do you agree?

Now THIS is a Glacier!
IPB Image
No doubt about this one. This is definitely a glacier. Notice how it even looks like you can see it flowing. How do I know this is a glacier? How many different glacial features can you see? Compare the characteristics of this photograph with those that I wondered whether it was a lake or a glacier. How do they compare? How are they different?

Same Glacier, but a Little Closer
IPB Image
Another shot of the glacier shown in "Now THIS is a Glacier!"

OK, hit my limit again. I think one more will do it!
