Day 13 - The Final Countdown

A 7:30 wake up. An 8 AM breakfast. A 5 minute car ride. 

And then it was time. Time for the final exam. 

Apparently, our PhDs had arrived in the mail that morning, because Guil kept repeating that "WE were the geologists". He and Lydia removed their scientific hats for the day, softly placing them on our unassuming undergraduate heads. 

Our task was simple. Describe the entire many-million-year formation process of the geological features of a 200-meter section along the Torres coast. Straightforward enough, right? 

We arrived at Parque da Guarita on the Southern coast of the state at about 9:20 in the morning. Three vast expanses of outcrop stood before us. How on Earth are we supposed to interpret all of this? "You have 5 hours," Guil said forebodingly. 

Oh. Well upon first examination, 5 hours seems like enough time. But many of us worked up until the last second, some even skipping lunch, in an attempt to flesh out a logical prediction. Examining, feeling, and even tasting the rock, we filled our field journals with observations and hypotheses as to what was happening back in the Ol' Cretaceous period. 

After a rainy and overcast afternoon (foreshadowing for our grades), we returned from the park to the hotel where we shed our wet clothes and tidied up before the formal part of the exam. 

What ensued next was undoubtedly the quietest 4 hours of the Maymester thus far. In an SAT-like setup, each student claimed a desk to themselves where we slaved away until the 7pm deadline: drawing sketches, balancing theories, and stressing out. 

Finally, as the clock tolled 7, we handed in our papers with our fingers tightly crossed. Guil and Lydia gathered us around for the reveal. With their geologist hats back on, they explained to us their interpretation of the history.

These unusual outcrops were filled with surprises! Basalt/sandstone breccias, sandstone dikes, and dunes just to name a few. Guil and Lydia revealed the likely succession as follows: a sandstone or breccia layer, covered by a basalt flow, followed by more breccias in some places, and finally another basalt flow on top. Groans and celebrations sprinkled the crowd with each explanation as Guil revealed the likely origins of the features.

It'll be a few days until we all get our grades back. But until then, we'll be crossing state lines back to sunny Floripa to enjoy another calm, peaceful free day of absolutely no shenanigans nor mishaps.

On the lookout for good Wifi for GoT,
Carsen Targaryen and Grant Snow

PS: We will be away from internet for a few days, but we will update the blog as soon as we can!
