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 soak our tired bodies in a natural hot spring, splashing around with the local brain eating amoebas and little red worms, the next best thing :-) 


We then got to an outcrop of our lovely TA Lydia’s research unit— Whakamaru. Pronounced fahk-a-ma-roo. We observed the pyroclastic flow deposit which featured a much higher crystal composition than the volcanic units we had seen thus far, and learned how this eruption erupted about 2000 km³ of magma. It kicked off a series of eruptions, known as the flare-up, and erupted 1/3 the entire volume the TVZed has produced in the past million years. This was a lot of information for our tired hearts to take in so we continued to Ohope and waited the next exciting day.


May 29th—the next day— Conrad’s second birthday— his American birthday—his real birthday. It began with a quick drive to a gorgeous beach with a lush forest right next to it. We had no idea of the huge mystery that awaited us deep in the forest. 


We began a short hike, surrounded by chirping birds and crashing waves. We finally reached the outcrop and began making our observations. We could not decide whether it was a pyroclastic flow, pyroclastic fall, or some sort of sedimentary rock. Our conclusions were soiled when, with the help of Lydia, we discovered that this outcrop was a mix of pyroclastic falls and soil horizons. 


This outcrop was none other than the famous Whakamaru, which was distinguishable by its incredible crystal content. We then escaped the forest with only Lydia being attacked by bird poop. After a relaxing beach side lunch, the next stop was another drive to an even cooler forest. This hike was special because we were told to not just look at the rocks but at the vegetation as well. Along the trail, there were huge boulders with trees grown on top and around them. 


The last eruption of the nearby volcano was about 100 years ago, meaning the trees we thought were hundreds of years old were only about 100! But how did these large boulders get here? We turned to the sounds of rushing water for an answer. A powerful lahar had formed after the eruption, which moved the boulders to where they are today. Following the sound of the river, we came upon a magical waterfall. Some of us even ranked this waterfall in the top three best waterfalls that we’ve seen. What else would we do in front of this beauty other than take a group photo? After heading back, we enjoyed a question and answer session on the TVZed and a delicious barbecue. We then headed to bed dreaming of the volcanoes we would see tomorrow.

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...

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 ...
