ridge (VRR) is a linear, topographically high feature that parallels the northwestern perimeter of lower Aeolis Mons (informally, Mt. Sharp) in Gale crater, Mars (Figure 1; Anderson & Bell, 2010). From orbital data, VRR is distinct from the subjacent and superjacent rocks in that it shows a strong spectral absorption attributed to hematite (Fraeman et al., 2013). However, from Curiosity images, the rocks in VRR are laminated mudstone like the underlying strata (Edgar et al., 2020). Rocks within the ridge are inferred to have been deposited in lacustrine environments, similar to the Mt. Sharp rocks below (Edgar et al., 2020;
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
