McClellan Butte. The app said this was some 9 miles roundtrip, so I was displeased when I passed the ~4.5 mark and was not yet there - not because of the distance in itself, but because the weather had become unpleasantly rainy and a bit cold, and I only had a light shell.
Didn't make it to the very top because the very top looked like this:
I was aghast; the maps show the trail going all the way to the top, but it's surely madness for the average hiker to attempt this. I am fairly adventurous when it comes to this kind of thing, but am definitely not comfortable going up an uneven rocky climb in the rain with a sheer cliff on the left and a steep slope of jagged wet rock on the right, leading down to more cliffs. On a clear, dry day I'd *maybe* think about it.
