(top) Mastcam R0 mosaic of Red Cliff area, Sol 2,038, product identifiers 01076900(1–4) (middle) ChemCam RMI mosaic (CR0_578416634PRC _F0700240CCAM04038L1) of portion of Red Cliff area colorized with Mastcam false color R612 (R: 1013 nm, G: 527 nm, B: 447 nm) to emphasize spectral differences are not controlled by stratigraphy. Multispectral image product identifiers are 0107620(01–21). (bottom) Mastcam R6/R4 (1,013:908 nm) ratio that with 3 × 3 median filtered applied to reduce noise. Pixels with deep ~900 nm absorptions are white, pixels without absorptions (ratio values <1) are black.
