About this work
It's hard to see in the dark. Most HiRISE images are are taken when the sun is at least 15 degrees above the horizon. (If you hold your hand at arm's length with fingers together, it's about five degrees wide on average.) However, to see what's going on in winter, we need to look at times and places where the Sun is just barely over the horizon.
