I hope this is monochrome enough...I tried a b/w version, but I like this bluish one better.
During a trip to Antarctica, the cruise ship docked to an ice floe, and the expedition leader investigated it whether it was safe to disembark passengers. In the end, we all had the possibility to walk on this ice floe, but of course it was not the same experience as the expedition leader must have had, when he stepped where no man has gone before...
