I didn't think air could turn that fast!! mind blown!! that explains this:]
Notice
how the snow packed into the high presser areas around the step box pounding out the abrasive corners into nice aero fillets changing the force vectors and pressure grandaunts ,this profile would yield a forward force instead of just down with less space to apply due to boundary air riding over the turbulent air represented by the snow-packed in. The snow on top of the bumper is caressing the pore converging diverging duct formed by the snow packed into the bed/bumper and body shape, filling the low velocity/turbulent zone on its surface making the transition to vertical smother.

there is a light breeze coming from the left at almost a right angle to the road(slightly a head wind ). the tufts on the top hainging over the duck bill as Aerohead calls it look like fish hooks insted if yarn.

Thank You Phil

Air makes a 270? 180 to go forward and 90 to go strait down the tailgate center, and progressing to outward but still down AND ATTACHED toward the corners of the bumper.
