Getting Up Close and Personal

I have to admit I am a geeky geologist. I love walking in the mountains, looking at outcrops and imagining how they formed, or how many dinosaurs could have potentially walked there. I wanted to start climbing, perhaps with a slightly different motivation than most people. Malin for example (as most climbers I guess) has the goal of becoming a better climber, she fantasizes about the difficult routes she wants to be able to climb by the end of summer. Her motivation is becoming a stronger, better climber. When I mentioned what my motivation for learning to climb was, I was met with raised eyebrows and suddenly had an idea for a new post.

My strongest motivation for climbing is that it provides another excellent possibility of getting really ‘up close and personal’ to outcropping rocks. I want to climb at different locations and rock-types, and see and experience the difference. I am serious. It might be possible to compare it with a biologist studying an animal from photos vs. actually spending time with the animal? Well, maybe I sound crazy now, and maybe my motivation will change with time, who knows.

Eventyrøya Senja

Aside from the attractions on Senja such as Senjatrollet (the world’s largest troll) and the traditional fishing communities (as well as a Halibut museum), the geology is also a reason to visit Senja. The northern and western coasts face out to open ocean and mountains plunge near vertically into the sea. According to some tourism websites, almost every aspect of Norwegian scenery and nature can be found on the island.

We have covered quite a lot on this blog about the Caledonian Mountain Building episode which is responsible for Scandinavian mountains in general, and talked about some of the rock types. A general rock ‘family’ that gets mentioned quite a bit are metamorphic rocks. Metamorphic rocks can form as either igneous or sedimentary rocks are altered due to either pressure (as rocks are buried in the crust) temperature (the deeper towards the mantle a rock is, the higher the temperature) or chemical alterations (i.e. when water passes through a rock chemicals in the water can interact with chemicals in the rock changing the mineral structure).

Sastrugi and snow waves

Most of you have probably noticed how the wind is capable to shape and polish snow surfaces, make fascinating structures, often similar to ripples and sand dunes. Fascinating to look at, but a hustle to ski on. I guess many of you are also very capable to point out the latest wind-direction based on the shape of the structures. However, some of these structures are very complex and it can be difficult. Examples are sastrugi versus regular snow waves, they are very different features formed by wind blowing on top of snow.  In this blog post we will touch a little bit into this, how they form in relation to wind direction, and how they are different from each other’s, and from ripples and dunes in sand.

Imposing dolomite marble cliffs also called “Norwegian Snow” on Storfjellet in Breivikeidet (Troms, Norway)

Norwegian version below.

Saturday, two friends (Morgan and Sten-Andreas (also a geologist)) and I went ski touring on Storfjellet in Breivikeidet, Troms. The days are so much longer now, and even though we had bit of an alpine start, we walked in sun most of the time. Nice to feel that the sun is starting to warm again after a couple of months of polar-nights.

Me and Morgan studying a little outcrop or block of rock on or way up the mountain, it got our attention because of the rare color. Turned out to be the first clue of what later to come! Picture: Sten-Andreas Gundvåg
