'Rapids Rock' is the buttress across from the Narrows and up the canyon another 100 feet. The rock is typical SSV ganite with discontinuous cracks and a little foliage. The rock is very solid compared to some formations in the area. Guided by Voices is the principle attraction, with a few new lines on the way. This is a traditional rock. Drills are not welcome except for the anchors to get down (even those are done to a minimum).

Eds. note Mechanical Man is the formation just downstream from Rapids Rock. It appears on pages 179 & 185 of B. Gillett's excellent 2009 S. St. Vrain guidebook.

Drive up the SSV. After passing The Narrows, you will note the rock off to your left and a pulloff just past.

To access, boulder hop just up stream from the formation or wade across much furthur upstream. The boulder hop is a little intimidating if the water is not at its lowest level (long jumps over fast water!). To gain the top, walk up the gully on the right side (lots of poison ivy!). We eventually got fed up with the gully and fourth classed up a crack system on the west wall to escape the ivy. Descend the same way or get creative with rapping.
