Just back from 7 days of hiking from Horseshoe Meadows down to the Kern River.... a loop.
Besides all the rain, of which lasted 4 hours or more each time (twice). I had an interesting encounter. I was at the Kern Hot Springs when I heard a rumble approaching.... louder and louder until, there it was, a military jet flying about a thousand feet above the river floor. Keep in mind that the jet was still considerable below the top of the canyon.
The jet reappeared a second time, and this time I I had a better view.
If you have ever been in the Kern River trench, it was incredible to think what this pilot was doing.
what is interesting is that around the hot springs, there is a slight turn that the pilot makes while travelling up the Kern.
