Paul,
I don't have the Tom Harrison map yet (but I will soon), but I called SEKI wilderness person yesterday who said that trail exists: One heading all the way down Big Arroyo to within ~2 miles of the Kern River, where it climbs out of the canyon to the south and over into Rattlesnake Creek, and then down to the Kern.
Looking it up on Gmap4, I'm pretty sure I can see it in the satellite views. Here's the "t4 topo high" view of a trace. If you zoom all the way in, switch to Satellite and zoom more, you can see the trail:
Gmap4Here's the satellite view of the junction (about a mile from the Kern) in Rattlesnake Cr zoomed all the way in:
Gmap4They say the trail over Sawtooth Pass is not maintained, but I am sure I can find my way. It was that section in Big Arroyo that is missing on the "t4 topo high" I was worried about, but SEKI says it's there. ...but then the SEKI phone lady was using the Harrison map as the authority.
