Figure 2

Box plot of 20 normalized Schmidt hammer rebound measurements (Rh) compared between BIF, a hand sample of canga (canga), surface canga (directly above VL-02 Cave), and walls comprised of canga in both Piety and VL-02 caves. Whiskers represent upper and lower quartiles. Significance (***) calculated using a one-way ANOVA with a P value of < 0.001.
