Biology: samples were collected from Harris Hills, the N side of the
Collapsing Road site. They are polka-dotted, and some flanks are also
orange colored. We suspect biological origin but it may also be made by
a concretion-making process. The samples are now in the incubator.
We have taken images to compare them with 2006 images.
We have found large concave slopes of dried river valleys North of
Harris Hills, we don't know how they were created since normally they
should be convex. It may be caused by landslide, but there are at least
5 of them one after the other.
Atmospheric phenomena: we have observed huge dust clouds and forming
dust devils East of Skyline Rim. The mountains far away are blanketed
by dust in the air. Maximum observed gust was 61 km/s during EVA 14.
