"The scene evokes the possibility of a dry lakebed."
Actually, in the photo, it looks like the rocks are emersed in about 1" of liquid water, with several inches in the foreground. You can even see ripples in the "water." Of course, they don't have liquid water on Titan. Maybe liquid methane, or maybe just the poor graphics.
Looks more like sort of gravel to me. And note the apparent wind scouring of this possible sediment around the one "rock." If indeed it's gravel and not sand, that is one heck of a wind that made such scouring.
