Twin Peaks

The sides of the peaks are of great interest to scientists.

When we look at the Twin Peaks we see distinctive structures on the sides of those hills. They are horizontal lines. Now what are those lines? That's the big question. Those lines could represent individual layers of rock, either sedimentary or volcanic, or they could be erosional features, benches cut in the sides of the hills like the Grand Canyon. We still don't have quite enough information to distinguish those possibilities. Now one of the techniques that we're using is called super resolution; this is when we take a whole bunch of pictures of the same thing and they're slightly offset. This allows us to get higher resolution than a single picture. And when we process those super resolution pictures we hope to be able to see more detail in what those horizontal lines represent.
