Yeah but the topo in CAJ '75 shows the route finishing at the same point as the Widowmaker, IE directly at the Camel's tail. Which it would not nearly do if it went up the circled buttresses (horribly bushy).
I wouldn't doubt that the whole thing could be a hoax but it would be interesting to climb the blue line as directly as possible just to see.
And doesn't CAJ 75 say that they first saw the route with binoculars from Goat Ridge (I assume, east of Goat Peak somewhere) and that they then went back the next day, or week, or something to climb it? In which case the fact that you can't see it from the approach to Goat is less relevant.
