Where I Am and How I Got Here

Hello! My name is Trevor. I am a Marine veteran and a third-year geology student at Pomona College. This semester I’m studying abroad in New Zealand. I’m halfway done with the first part of my program, which is a five-week field camp all over the North and South Islands.

That’s me atop a hill that was located near the center of our mapping area and offered astounding views in all directions. I’m holding the map board and field notebook I used to record my findings.

 

I must admit, I’m a little surprised to be here. When I started at Pomona two years ago, I had no plans to study abroad. I was lucky to travel a lot growing up, and I’d recently returned from a seven-month deployment to Afghanistan. I thought I’d be content to hang around campus all four years, but my curiosity got the better of me. Some friendly encouragement from my girlfriend (who also studied abroad while at Pomona) was the final push I needed to take a step out of my comfort zone. Here I am.

Kura Tāwhiti Conservation Area: Known to non-Maori speakers as Castle Hill, these limestone cliffs featured prominently in the Chronicles of Narnia movies. That’s my group gathered in the background.

I had three main concerns about leaving home, all of which still hold true to varying degrees. 1) After field camp finishes, I will have to do my own cooking for the rest of the semester. I hate cooking. 2) Cars are my greatest passion in life, but my program does not allow me to own a motor vehicle while in New Zealand. 3) I sunburn easier than anyone I know. New Zealand’s depleted ozone layer means I will have to be even more careful than usual.

I haven’t yet had to cook for myself, and I’ve only been away from my car for a few weeks, so the only concern I’ll address now is the sun. Yes, it’s bad, but it is manageable. As long as I reapply sunscreen every 90 minutes I know I won’t burn. I’ve only burned once so far, and that was on an overcast day in the field when I tried to make due with only three sunscreen applications instead of the usual five.

Otherwise, adjusting to field camp has been pretty easy. The Marines prepared me well for this physically demanding and highly structured environment.

Rivers cut through rock leaving behind excellent exposures for us to study. The only downside is soggy socks.

The sea foam at 14-Mile beach was knee-deep and jiggled in the wind like Jell-O.

Torrential rain damaged much more than just this trail. The flooding and debris flows it caused closed major roads, delaying our trip to the West Coast. Professor Sam described it as the storm of the decade. According to weather reports, more than a foot of rain fell in a 24-hour period, and the wind was gusting at almost 100 mph!

My group descends a hillside at Castle Hill Basin after a long day in the field. The area we mapped measured two square miles and extended all the way to the foothills of the tallest mountains in the background.

 

I’m here with 22 geology students from American liberal arts colleges. We won’t mix with the local New Zealanders until classes begin at the University of Canterbury next month. For now, it’s just us and a rotating cast of professors and teaching assistants. I like that everyone has a friendly attitude.

A few of us pause for a photo op during a steep ascent of a limestone ridge. Tectonics have uplifted the limestone beds so much that in some places they are vertical, or even overturned. The beds continue onto the terrace behind us. You can see the vertical bedding exposed in the small hill to the left of the larger one. Also note the landslide scraps on the right of the photograph. This is a very active landscape!

Professor Sam (left) and student Monte (right) try to distinguish between the bedding and cleavage planes of this sandstone at 14-Mile Beach. Bedding planes show how the sediment was originally deposited. Cleavage planes are where it later fractured. Ordinarily, they’re easy to tell apart, but these beds have been steeply uplifted. By measuring the orientations of bedding and cleavage at several locations across the beach, we were able to piece together the size and shape of a fold that was thousands of feet wide.

Each day we spend six to eight hours outside in the field making observations and taking measurements. Sometimes this means miles of hiking over hills and across rivers. Each night we spend a couple more hours in the classroom combining and interpreting our data. It’s a lot of work, though we do occasionally get days off to relax indoors or go off exploring on our own.

The university’s field stations serve as our base of operations. They have everything we could want: bunkrooms, classrooms, kitchens, bathrooms with hot showers, and half-decent internet. So far, we’ve spent nine days at Cass Field Station in the Southern Alps and five days at Westport Field Station on the West Coast. In a couple days, we’ll fly to the North Island to study volcanoes. Below are some more photos of the sites we’ve visited so far.

On the West Coast of New Zealand’s South Island, we hiked toward Cape Foulwind (the rocks in the distance) where we surprised a seal sleeping in the plants. It was so well hidden we didn’t notice it until we were almost on top of it!
