It is rather painful to read Mr. Scaruffi's route descriptions of modes of access to VDC, some of it rather suspect given my experience. What he describes is possible but so sketchy and oddly described that I wonder if he really got where he said.
Look at his photos. The ones labeled "mountains to the east" are VDC for sure; why not say Ventana Double Cone? Yet the ones labeled Double Cone and the VDC fire lookout don't look like any view I've seen of VDC and I've seen it from all 4 angles up close as well as distantly.
Look at his GPS coordinates. They are nonexistent except for a couple of the jct. of PRT with Ventana Camp Trail and the BS River at Ventana Camp (which coordinates actually mark the top of a peak south of the jct. of PRT/Ventana Camp Trail). Why so darn few exactly indicated coordinates for such totally unnecessary locations and a total absence of coordinates along the really extremely difficult routes? If he really seriously wanted to prove a route and make it something to follow, would he not give the exact coordinates for the hard parts? Maybe a GPS unit is too weighty to carry?
His supposed routes are way too blithely sketched. I've hiked Mt. Manuel to VDC once (dropped down to Ventana Creek after traverse due east from Mt. Manuel until ridge turned N, and thence up western wall of VDC - entailing a little mountain climbing) and I've hiked up Ventana Creek about 10 times. His experience doesn't jibe with mine much.
Ventana Creek route: This is almost a throwaway route but in my book is rather difficult. Why did he not mention the 85-ft waterfall 3/4 of the way up? It is way out of the ordinary and quite a remarkable, almost never seen feature. Also, since 1994, there is at least one small waterfall that would be very difficult to ascend. How did he do that one? How did he get around the 85-ft waterfall? It involves serious rock climbing or else a treacherous climb of a steep landslide section immediately adjacent.
Ridge routes: I got lost trying to follow his directions of 2 different ridge routes. Apparently, assuming he did the routes, he wrote about them from memory w/o benefit of map (which he otherwise displays so why not use place names, as has been commented by others?). One ridge route seems OK for a while and then he loses me later on with badly described zigs and zags that didn't make much sense to me, reading descriptions on one hand with topo map on the other side.
Anyway, either Mr. Scaruffi' did not actually do these exact hikes or he is a phenomenon of goat-like heroics. Actually there is one photo of him showing a person at least willing to get really down and dirty (fearless, at least). (What was the chopper ride about - did he have to get rescued?)
In any case, beware using his descriptions to repeat his supposed feats. You'll get lost or stuck in the middle of nowhere come darkness, on a "day hike" that I expect would take far longer.
Of course, all my experiences have been laden with pack (40-60 pounds). So unburdened, maybe one could do a 20-mile, 4500-ft climb and return through some extremely difficult terrain in a day, and that was his "easy" route! Possibly. Likely? Really?
