Fruitvale Station vista

24 March 2014

Sometimes the weather is clear enough, but just hazy enough, to reveal the details of the landscape for quite some distance. A week ago the view down the line from the Fruitvale BART station looked like this.


I know it’s a small image, so click on it for an annotated 1000-pixel version. Most of the view extends beyond Oakland city limits. The farthest peaks are in the Ohlone Wilderness east of San Jose, some 30 miles away. Once you become familiar with our skyline, it’s never boring.

Lower Colton

31 January 2014

You may think of Snake Road as the ridge road that climbs the crest between Thornhill and Shepherd canyons, but it’s really Colton Boulevard. For a quiet hike above Montclair with views, you want Colton. Its lower part runs north of Snake across ground underlain by the Redwood Canyon Formation. Here’s a roadside outcrop.


I didn’t even notice the parallel fractures until I opened the photo at home. They probably represent a bit of extra cementation, thanks to a late pulse of fluids, but they may also be original bedding.

I mentioned views. If you loop around Mendoza and Mazuela Drives you can view some immaculate houses and grounds, but I like the big empty lot on Mazuela that overlooks Pinehaven canyon; click it for the bigger version.


Huckleberry saddle

18 November 2013

The entrance to Huckleberry Botanic Regional Preserve is at a low point in the spine of the Oakland Hills, where the steep eastern arm of Thornhill canyon has cut headward toward the equally steep canyon of San Leandro Creek. Both canyons are steep because the rock between them is the tough Claremont chert. The saddle between the two canyons provides good views to the west and east, and a little path (labeled Huckleberry Path on the map) leads north from the Huckleberry entrance, a private entrance to the preserve for the residents of Elverton Drive. That’s where I got these pictures, first looking southwest toward downtown:


and due west, over the opposite wall of Thornhill canyon, toward the Golden Gate.


Turn around, and it’s just a few steps to find these views of the Las Trampas Ridge area—


—and Mount Diablo, which never ceases to surprise me when I see it from Oakland. I think of Diablo as a whole different domain, reachable only by a drive through the tunnel and not visible west of Lafayette. But here it is, looking downright neighborly.


Only a few Oaklanders get to see the view east; we’re a westward-leaning city.
