Rock Crawler Stone
Rock Crawler Stone is Brig's big stonefly nymph, started after a live salmon fly nymph on the Henry's Fork turned out to be three times the size of the largest pattern in his box. Chewy worm chenille gives the bulk that regular chenilles lacked on a large hook, and a scud skin wrap suggests the hard shell of a stonefly. It can be tied in several colors to match the hatch. Brig and his friends have fished it on the Henry's Fork, Snake, South Fork and Provo. Tied here on a size 6 hook.
