Oakland’s infrastructure includes two major powerlines across the hills. One starts from the 1922-vintage substation on Landvale Road (the Claremont Substation) and runs parallel to route 24. The other starts from the vintage substation at Park Boulevard and Grosvenor Place (Substation X) and runs up Indian Gulch, Dimond Canyon and Shepard Canyon. Both of them offer little islands of open land, secret parks, around the support structures.
This idyllic spot, photographed in November, overlooks Indian Gulch between Hollywood Avenue and Glendome Circle.
And here’s a view of the Claremont Substation and powerline just east of Lake Temescal, taken in October 2008. This bit of empty land can be reached from the top of Pali Court or by a scramble up from Broadway or another scramble down from the fire road past Swainland Reservoir.
Like geologists, powerline operators have a totally different view of the city than most people. I’m a little surprised there aren’t more powerlines here, but two is plenty. (A third, smaller one runs through Oakland lands up Strawberry Canyon from the Cal campus past Grizzly Peak.)
