There is a sign for Robbs Gulch along the CA-39. I parked shortly after the sign in a turnout directly across from the canyon.
I was delighted to meet a good flow of water immediately upon entering the canyon.

Not much of a use path in this place, so I had to do some crawling under and around branches.
After maybe a half-hour of scrambling around, I happened upon a 15-foot waterfall obstacle that stopped my progress.

In dry conditions you could probably find a class 3/4 route up the left side.
I then drove down the road a bit to Polecat Gulch. No sign here. Just a mile marker to find.
Not far up the canyon is the first impressive waterfall.

This fall can be bypassed on the left using an exposed, narrow use path (class 2). Then the canyon lets you relax for a few minutes.
But soon there is this amazing thing.

Getting around the second, 50-foot waterfall would have taken too much effort, so I turned around.
I still needed to check out Browns Gulch.
A road sign identifies it as Pejsa Canyon,
but Tom Harrison labels it Browns Gulch. And I like the idea of there being three gulches in a row, so I'm going with Browns Gulch.
After a steep drop-in on the left side of the canyon from the road, the gulch is somewhat wide initially. There is a large storm drain on the right side under the road, which takes some effort to reach.
Heading up-canyon, a use path crosses the stream several times.
The path soon evaporates and the real scrambling begins.
I kept climbing for maybe an hour (before hitting my turnaround time) and did not encounter any class 3 obstacles or waterfalls requiring scary bypasses. The gulch does, however, have some impressive cascades.
And I did reach a point where the canyon narrows so much that I would have needed to step into the stream to continue forward. This is where I turned around.
If you go during a wet time, I definitely recommend waterproof shoes. I must have dunked my shoes ten times, yet my socks stayed mostly dry.
Also, I don't think it's possible to avoid the poison oak in these canyons.
