  Dust transport and deposition behind larger boulders on the comet
67P/Churyumov-Gerasimenko (67P/C-G) have been observed by the Rosetta mission.
We present a mechanism for dust transport vectors based on a homogenous surface
activity model incorporating in detail the topography of 67P/C-G. The
combination of gravitation, gas drag, and Coriolis force leads to specific dust
transfer pathways, which for higher dust velocities fuel the near nucleus coma.
By distributing dust sources homogeneously across the whole cometary surface,
we derive a global dust-transport map of 67P/C-G. The transport vectors are in
agreement with the reported wind-tail directions in the Philae descent area.
