There was a break in the seemingly endless line of storms moving off the Pacific into California. We managed to sneak in a quick trip during this break. If you're curious why it took so much time for me to complete my last trip report, this is one of the reasons. Here we go -

A fair (???) division of labor! "I've just finished writing this. I'll call the Lady inside to help edit. She's outside shoveling snow."

 

We love Johnson Canyon. Thanks for the trip report!

It had to be old because it was made in the USA.”

Sad, but mostly true…

 

Thanks for letting us tag along, it’s been 14 years since I’ve been in Johnson Canyon.  I’m glad the old Airflow is still in place.

Those concentric circles in the rock are really beautiful.  Any idea how they formed?

Vic, geologists call that 'flow banding'. Very common in extrusive igneous rocks such as ash flows. Think of the swirls in a marble cake batter. The ash comes out as a dense ground hugging cloud of gas, half melted glass fragments and chunks of all kinds of rock and debris. Look up Nuee Ardant. When the mix of gas and ash cools enough to turn into a hot gloppy mass, that is when the flow banding forms. Later, when long cooled, erosion carves down into the rock, like you would slice a marble cake, and voila -- you have fascinating color bands.

Another great report.  A few similarities to our last trip there, when we camped near the airflow one night, and out at the mouth where you camped another night.  We hiked up the canyon and ended up on the higher route and ran out of time before making it to the ranch as well.  We didn't ever spot the lower route though.  Darn short winter days anyway. Thanks for the write up and the pics!
