When the region of interest is white-on-white (as with these Modis images), the contrast can sometimes be usefully expanded to make fuller use of monitor dynamic range. This is especially suited to fractures.
One fast way to do this is mask out the rocks, normalize the remaining contrast to 0,255, and then equalize the (global) histogram. This would take about 15 seconds of twiddling in Gimp or similar.
A better way of bringing out features is to do this locally. For that, look for a menu command called CLAHE in your image processing software. A round-trip to ImageJ2 (free, platform-independent) takes around 45 seconds on this size image.
This time of year, Landsat provides very nice coverage of Nares (via
http://earthexplorer.usgs.gov/). The LandsatLook natural color is a small fast file with quite good resolution; the region of the two islands is shown in the snippet below from LC80292482015167LGN00. Much of Nares lies within this single image.
