Well, if you only want 4 radials, you can make them shorter. The 
additional length won't get you anything.

What I would do at a location as pictured (although in my case I would 
need a helicopter to get there) is to use your tripod vertical as the 
center support for an inverted V near (not too near) a sharp dropoff in 
the direction that you want to work. Bring some duct tape and tape the 
ends to the ground. Even if the V is only a few feet above the rock, it 
will be a *very* high dipole in the direction of the dropoff.

By the way, another problem of a vertical in such a location, is that 
even if you get a good counterpoise, the reflection from the Fresnel 
zone (a few wavelengths) will be poor because igneous rock is a very, 
very poor ground!
