HAFNARFJORDUR, ICELAND- [guest bloggers Travis and Lindsey]
We only spent about 2 hours in Undirhlíðar yesterday due to the gale force winds that sent basalt shrapnel flying into our faces, in particular our eyeballs. It wasn’t raining luckily, as raindrops probably would have been lethal at that wind speed. We made an awesome discovery though on the Northeast wall- A lava tube! We were climbing up a talus pile when we noticed the hole leading down into the wall.
Here is what Travis and I hypothesized:
1. Troll den
2. Center of the earth
Unfortunately, Dr. Pollock didn’t let Travis get into the lava tube, though he tried his best to convince her. Reasons Travis thought getting inside the lava tube was a good idea:
1. We would find the base of the pillow unit
2. She would become the most famous geologist of all time
3. Dr. Wilson would let me
Reasons Dr. Pollock said no:
1. Because I said so
We then moved on to the West wall and found basalt that looked drastically different than anything we had found in the East wall.
Sizable olivine and plagioclase crystals were in all of the rock units we saw in the Southern end of the West wall.
Today is our last day of field work in the quarries, we’ll keep you updated on our continued adventures.
