The Final Post - Parting Thoughts...

Loren What was my favorite part of the trip, you ask? Even if you didn’t ask, I’m going to tell you it was Whakapapa. Whakapapa was not what I expected and truly surprised me, which probably contributes to it being the best. After a day of driving and fixing a flat tire, we basically sprinted up the long and steep trail so that we could make it to the top before sunset. I’ll be honest, I was not impressed at first. It was just a foggy, flat area with a few small hills. Then, all of a sudden, the fog lifted and WOW—we could see Ruapehu and Ngauruhoe towering above us. I was in awe, and it only got better from there. We finally reached the top, which was well worth the sprint. Surrounded by sparkling lakes and impressive volcanoes, I knew this week would be a good one. Not even the promise of a mapping exercise later that week could discourage me! The entire next day was spent on Ruhapeu, learning the basics of volcanoes. I had been excited about the volcano portion of the cour...

Days 20 and 21: Conrad's Birthdays

May 28th— the long awaited day—the big day—the only day—Conrad’s 19th birthday. Unfortunately for him, the weather was rainy and chilly and mushy on his day; but fortunately for him, he was one year older and could finally kick it with the rest of the big kids. After wishing our first of many happy birthdays to C-rad, we GABEd it up for a day at Wai-o-tapu.  “Wai-o-tapWHO?” I hear you scream. Dear readers I’m so glad you asked. A bubbly geothermal wonderland, Wai-o-tapu was the perfect example of New Zealand’s incredibly efficient magma sourced geothermal system that produces 1200 megawatts of power. For scale, just one megawatt powers 1,000 homes.  If that doesn’t make you say, “wowie!” I don’t know what will. After learning from our resident experts about the thermodynamics behind the system, we had time to romp around the park and watch the mud bubbles rise and pop and boil, resisting the urge to jump into the steamy mess.  We did, however, get to s...

Day 19 - Taupo Ignimbrite & Redwood Forest

Ashes to ashes, pumice to pumice, for Taupō thou art, and unto Taupō shalt thou return. Guil 5:26 Today, for the last time, we learned about our old friend, the Taupō sequence. Dave, our trusty van, delivered safe and sound to our first outcrop of the day, a wacky series of falls and flows. Guil and Lydia, barely able to restrain us, set us loose. We DEVOURED this outcrop, hand lenses and map books in hand. This was a peculiar outcrop, with strange scouring and elusive layers, but by an astounding group effort, we were able to crack the secrets held within.  Our first clue was the sub sorted, clast supported subtle layering of the bottom unit, indicating it was a series of proximal tephras, falling ash and pumice. Above this is where it got confusing, there were captured clumps of the previous unit and a very wavy contact. With a little help from our instructors, we concluded that it was a slurry of ash and water caused by the increased rainfall after the eruption that sat ...

Day 17 - Tongariro Crossing

Oh gosh. Look at us, blogging again!!! We were gonna stop, but the people demanded it so here it goes, the day you’ve all been waiting for is here, the fateful. Tongariro crossing, the line separates the kids from the big kids, the royalty from the plebeians. We set out this fine morn with determination in our hearts and rice krispers in our bellies, the perfect fuel for a day of labor. Then we got to the spot. The Mangatepopo valley trailhead. It was an awesome spot to be sure, but a spot that we would come to despise in the coming days (spoilers).  The geology was pretty cool tho, we stopped at a couple different places in the beginning of the crossing to see some interesting features that were important for our mapping exercise the next day. We first saw an area with the Taupo ignimbrite. Then, we saw a lava flow were top and bottom volcanic breccia as well as a massive rock in the middle.  We then saw a series or lava flows from a different volcano. Lastl...

Day 16 - Logging data

Once upon a time in desert road flats, after revisiting our pyroclastic flow from the day before, our merry band found columns of pumice in the desert wasteland. Not your normal deposition feature, these tabular columns of larger pumices had blown out their matrix leaving behind elutriation pipes.  Our next adventure was into a pyroclastic fall that had been carved out just enough for us (without our backpacks) to squeeze into.  After our usual heated debate (during which Guil, Lydia, and Brad left us to fight for a consensus on ages and lithics) we left for an even cooler rock! A sparkly, shiny, magical colored rock awaited us. A funky little anomaly, it had us throwing around all guesses to what had caused it. Eventually it struck us - LIGHTNING. Possibly the coolest thing we’ve seen, we were busy giving the rock a photo shoot while being taught that it was a fulgurite with vaporized charcoal and reheated pumice.  After, we learned about the charcoal ...

Day 15: A Slippery Slope

After exploring the realm of effusive volcanoes at Ruapehu, we ventured out into the unknown world of explosive volcanism. We started our day with a hot mystery to solve: fall or flow? We were taken to 2 outcrops that were textbook perfect examples of each volcanic feature and set upon characterizing them. Two very different pyroclastic depositions were evident--one with big white pumicey clasts with no beds and one tall hill with clear layering and varied grain size-- but there was a steamy debate as to which was flow and which was fall. Left without the guidance of Guil, Lydia, and Brad, the gang was left to our own devices to figure out which was which.  Leaving our mystery up in the air, we headed to our third stop - a hill. Bushwhacking our way up through towering grasses, we traversed our way to a place that looked suspiciously like the second outcrop. After another heated debate amongst the students, we eventually learned that this was, in fact, a combo of pr...

Days 13 and 14: Trip to Whakapapa and up Ruapehu

Hello readers! Welcome to our blog today! Very excited to talk to you on this great day. Not five minutes ago (what feels like at least!) we embarked on our journey, one we would never forget. After arriving in the North Island and spending a free day in Wellington we were impatient to see what the geology of this landmass could hold. And boy were we not disappointed. Our first destination: Whakapapa! Home of the southern edge of the North Island's Taupo Volcanic Zone (specifically Ruapehu volcano and the Tongariro volcanic complex) and a great ski resort, we happily rested our tired little heads for a night at The Skotel. After a good sleep, we began our quest...volcanoes.  We started our day in Happy Valley on the slopes of Ruapehu, a "huge ass" volcano. We studied some puzzling cliffs and made some estimates on the number of units present before focusing on a unique cliff face. After analyzing the different types of rock and orientations present, we conclud...
