Sand..........That looks like a fish catcher there , early spring , even when it's running high and muddy , it seems like a sculpin will often save the day , and that one looks as close to the real thing i've ever seen. When do sculpins spawn? I ask this cause on the down east spring creeks , at this time of the year (a spot on LeTort comes to mind right away) the sculpins would be out on top of the cress and weed beds chasing each other around , it was like a sign of oncoming spring , would happen every year. VERY NICE FLY!!!!
p.s. those sculpins were either fighting or f*****g
