Today I went to the Mitchell Canyon entrance to Mt. Diablo, a part of the big mountain I’ve never visited before. I hiked, mostly off trail and across country, up and down some very steep slopes, slick with tall grass. Everything’s still green, for now, from the recent rainfall we’ve had. But California’s snowpack’s 40 percent below normal and we’re facing another deadly dry summer and autumn. So it felt good to enjoy a brief, ephemeral springtime today for two or three hours.
