Schematic illustrating subsurface shear from emplacement of ejecta from Linné Crater on the Moon in plan view (top) and cross-section view (bottom). The plan view illustrates that ejecta sitting at 1.09 km from the rim (one crater radius) plausibly landed at 0.93 km and slid to the final resting place. The subsurface (bottom) is presented for illustration purposes only and is not meant to imply quantitative depths. A variable regolith strength profile with depth may limit the applicability of our observed logarithmic shear profile.
