Walking in a Rocky Wonderland

In last week’s post, I discussed how a few places we have visited have created programs designed to teach certain audiences about their subject, be that the history of jute or the development of bridges. This week my focus is still on education, but in a more general sense: how can learning spaces outside the classroom affect what and how we learn?

Consider my expedition to Siccar Point, arguably the most significant geological outcrop in the world. It was here, in 1788, where James Hutton found proof of his theories of the geologic unconformity (a gap in the geologic record) and his ideas about deep time. In the classroom, thousands of miles away in West Lafayette, I learned the facts about Siccar Point in the context of the history of geology, with a few interesting pictures to illustrate the point. I can remember thinking “that’s a nifty outcrop,” my professor (perhaps jokingly, perhaps not- it was sometimes hard to tell) say that geologists have a religious experience when they visit this site, and not much else. When the opportunity arose to actually visit this mecca of geology, I knew that it was important, but had almost no idea what I would actually learn from the experience.

Gaining access to the point was both more and less difficult than I expected. More, because I had misinterpreted the online directions I had obtained and ended up walking eight miles instead of one and a half, and less because there was a significant number of path markers and “you are here” type maps along the way. The Coastal Path walk itself was incredibly beautiful, with views from the cliff tops over the North Sea for most of the journey.

t the trailhead marking the location of Siccar Point, there was an interpretive sign explaining just why in the world this location is important, and why you should visit. It summarized Hutton’s findings, and described how those findings went on to affect the development of geology and of science in general. While this information wasn’t new to me, I felt that just by reading it in this setting, less than a kilometer from the point itself, made it more significant.

After a tense ten minute walk through a pasture in which I was forced to dodge innumerable piles of cow leavings, I found a second sign, this one specifically discussing the geology of Siccar Point. It described the order in which the geologic events occurred and how we know those events occurred. Again, I had already been exposed to this information in class, but now that I was just a few hundred feet from this historic site, it suddenly had more weight. What I was about to see was history, and it was personal. This was one of the reasons I applied for this study abroad in the first place, and the fact that I was actually there, at that moment, made the information I already knew become personal as well.

And then, finally, I climbed down the last hill and got my first view of Siccar Point. There is nothing quite like being somewhere you have seen in pictures, read about in textbooks, known that, although you might want to get there sometime during your life, it is probably out of your reach, and then suddenly you actually do get there, and realize that the pictures don’t do the place any justice and the textbook descriptions suddenly seem so clinical and meaningless. One of Hutton’s traveling companions remarked that “the mind seemed to grow giddy by looking so far back into the abyss of time” as he described the scene at the point. When I first heard this, I thought that while it probably did feel significant, to say that it caused giddiness was probably an exaggeration. I was wrong. I spun around, trying to take it all in at once. I hopped from rock to rock, knowing that this was exactly where Hutton had been and what he had seen, and even though that was 226 years in the past, it was less than a moment compared to the true age of this place. I touched the unconformity, just because I wanted to see what 55 million years felt like. And I took my one (and only) selfie for this six week trip with Siccar Point in the background. I did, in fact, become giddy.

Actually being there, seeing this with my own eyes and reading the signs along the way, allowed me to understand the idea of deep time in a way that I never had before. It was an idea, an abstract concept that I understood but didn’t really get. I get it now. Thinking about deep time still makes me dizzy, but now I understand it not as a sense of confusion, but one of vertigo as I stand at the top of a cliff with no base, looking down into a past so distant as to be unknowable except for the evidence that survived hundreds of millions of years so that I could stand there on the shore of the North Sea in Scotland with my mouth open, speechless.
