First Vantage guidebook (1991) with Sensemilla/Blo...


Stems and Seeds little brother.

Not quite as classic as S&S, but every bit as fun. Scramble up to a belay from an upper pedastal at the base of the stem box. A tricky start will get you going and good rests will keep you going. You can get gear in both cracks but better to pick one and go with it (left).

Near the top, most people choose to exit on the right hand crack though you can continue straight up, either way watch for loose rock...

A bolt anchor exists at the top.


Left of the bolted route Hakuna Matata. Look for an obvious stem box that starts about 20 feet above the trail.

Like Stems and Seeds, easier to get the wide stemming if you are tall. The same goes for most thin cracks at Vantage, you have to fire in the pro quickly else you pump out, so if you pick the wrong piece, it gets harder. This looks intimidating, but if you keep moving, there are good holds after thin parts.

A few FA details: Black and Veldhuisen, Spring 1987. Laurel (sp?) and I took turns placing gear and cleaning on lead – lots of dirt and rock fragments came out of those cracks. A microwave-size chunk high in the right corner shifted but stayed put! Laurel got past it and topped out. We named the route 'Block Party' and rated it 10b. Couple years later I came across the first guidebook with the route on the cover and the new name Sinsemilla - first I'd heard of it..
