|Figure 2. A closer look with at the alcoves and lineated valley fill seen in Fig 1. The locations of these THEMIS & higher resolution MOC images are marked in Fig. 1a.
d)The outflow of two ridged lobes from alcoves (bottom left and right) as they join a major lineated vally fill of area C (upper right) near the convergence with B (Fig. 1c). The left lobe is swept westward, forming broad arcing folds while the right lobe is increasingly compressed until it resembles a tight isoclinal fold. Both lobes ultimately merge into the general lineated valley fill parallel to the valley walls.
e)Detail of siedways lobe-like flows converging into the lineated valley fill on the valley floor, where flows merge from areas A and D.
f)A major east-facing zone of multiple alcoves and converging lobe-like flows in the more disatant reaches of the system, along the edge of the northernmost large mesa (area G). Note the concentric-outward ridges reaching out from the alcoves and their progressing compression, folding and flattening as the ridges deform and become part of the lineated valley fill on the valley floor.
g)The northern reaches of the lineated valley system. The lineated valley fill splits in two (bottom right) and flows around a massif to create a broad up-flow collar and a diffuse, down-flow wake.
