Excellent, Frank! Thank you! I can see it in the crosshairs on this satellite view. Looks like a few car lengths to the east of the actual turnoff.

Note: The map is interactive, so you can zoom in and click/drag it around. Yaki point is a mile north, the trailhead is on the left (west) spur at half a mile.) You can also switch the map type (upper right corner) to "t1 Terrain" for Google's terrain view, or my favorite, "t4 Topo High". Gmap4 is the best!
