Anyway, the spot where the side trail split off to go to La Barge Canyon was where I thought it was. Since it isn't a real trail, it's a little steep in spots, and difficult to follow (hard to see) in some spots. It enters the canyon about where I thought it would, just a few yards upstream of the lake.
Last weekend, I had thought about backtracking a little ways and seeing if I could find the trail out. It was close to being dark, though. I'm not sure I would have been able to find the trail.
There was a nice breeze blowing through the canyon, and it was shady, so I hung around in there for a while eating snacks and taking pictures. It's a prettier place when you know the shortcut out.
For most of the time that I was there, there were some quail making quail noises. They make a lot of different kinds of noises but I don't speak quail so I don't know what they were saying. Anyway, I was wishing I had something with me to record them. I'll have to add another gadget to all the junk I carry on hikes.
