Edge of the Sea is an excellent climb on the Riptide Wall. It climbs up various cracks just right of an arete. Scramble up easy rock to a hand crack. Cruise up the crack (5.6ish) until it narrows to a thin finger crack. Climb through this (crux) and link it with many other small cracks more or less straight up to a ledge. Then use the anchors for Astroprojection.
