Panel 1: He's a regular Sherlock Fucking Holmes, that Mark Trail. No doubt, he's made an extensive study of tread patterns and correlated them to the track depth created by a wide variety of vehicle body types and weight. This, of course, explains how he knows a van made those prints and not a heavily-laden Oscar Mayer Weinermobile parked for the evening.
Panel 2: Now, I'm no artist, but is all this exposition really necessary? Couldn't the JS have adopted the novel (for it) bird's eye persepective and shown us the tracks backing up to the cliff with Mark saying something ludicrous (but brief!), such as: "Hm. The van backed up to this cliff. Why?"
Panel 3: Having adopted my artistic and textual suggestions for panel 2, the JS would be well-advised to use the following panel for panel 3:
I think you'll agree that this is a much more appropriate response to finding a gigantic toxic dump in the middle of the woods than whatever Mark is going to say tomorrow...
