We descended to the junction with these East branches of Upper Bear creek at just below 4000ft. The available trip reports describe extensive marijuana cultivation in these East branches. In the West branches that we traversed, there's some black tubing, and some signs of activity, but not a lot. And it all seemed old and long-unused. When we hit the junction at 4000ft, we immediately found empty fertilizer bags, camp trash and a decent use trail along the canyon. I haven't seen the East branches yet, but the canyon on our end was full of waterfalls, and it'd be a lot of work to set up operations there. If it's easier on the East side, I'd spend my time there too.
Once we dropped down the steep upper areas, the canyon becomes woody, acquires water, and is generally pretty nice

Some small waterfalls are encountered towards the beginning

As you descend, the channel narrows, and you hit a number of significant waterfalls. All have bypasses with varying amounts of exposure. Definitely requires hands and good grip on your shoes, and falling is not recommended. But otherwise quite doable. The drops are dramatic in places





But then you get to go around, and look at the waterfall faces, some of which are really nice



We saw some snakes


(and an unpictured unalive garter snake)
And countless butterflies and countless ladybugs



And this:

And I claim I found a big horn:


It's really old and worn, and MAYBE it's just a piece of wood, but the texture made me think it's an old, degraded horn.
Nobody goes here, so we grabbed countless birthday baloons, and had ourselves a very merry time.
