Flash for Hash starts in the finger/small hands crack between Gold Bug and Hidden Gold. It is difficult to say where the crux lies; most of the crack can be avoided due to the well-featured face on both sides. Avoiding those holds, I found the start to be a little tough and the upper half of the crack yields better to a layback than to hand jams, at least for my hands. Finish above the crack, up the face on fairly large edges, between Gold Bug and Hidden Gold, clipping the bolts on either side. This route is usually done as a TR from the anchor for Hidden Gold.
