Comparison of red‐toned landscapes in the Pettegrove Point and Jura members as observed by Mastcam in RGB Bayer filters, white balanced unless otherwise noted. (a) Pettegrove Point L0 mosaic mcam10608 on Sol 2,013 and (b) Pettegrove Point L0 mosaic mcam09471 on Sol 1,830, showing smooth texture. (c) Jura L0 mosaic mcam12082 on Sol 2,256 in the vicinity of Rock Hall showing rubbly texture. (d) Example of a small gray patch in Pettegrove Point, in the vicinity of the Stoer drill site, L0 mosaic mcam11410 on Sol 2,129, stretched to enhance color differences (and to compensate for the effects of moderate opacity increase during the 2018 dust storm). White bars indicate approximate scale in foreground for reference. Viewsheds for mosaics (a–c) are shown in Figure S1.
