My guess is that it's most likely a few stones were kicked up by Phoenix's landing - in particular one of a pair of stones just above the little indentations looks like it has rolled/bounced (showing a darker underside and not embedded in the finer regolith). The indentations would be where the stones skipped across and bounced in the fine soil?
