Distribution of boulders (red spheres) with wind tails (arrows) on 67P projected onto a digital shape model by Preusker et al. (2017) with 67P’s morphologic regions outlined (El-Maarry et al. 2015). The arrows’ directions represent wind tail orientation including inclination and thus illustrate the presumed directions of the incoming particle streams, and their colors indicate the wind tail lengths. The boulder sizes are matched by the red sphere sizes. Most of these features are found in the Ma’at and Serqet regions, which are located at “the top of the head”, i.e., the northern part of the small lobe (Otto et al. 2017).
