Inner Coast Range
Flag Hill at Sunol Wilderness is a slab of ancient sea floor which, in response to pressure from below, was tilted up more on one side than the other, revealing a cross-section of its sedimentary layers.
The hill shows a vegetation pattern typical of the inner coast ranges. During summer, the hot sun dries the south-facing slope. Only grassland and soft chaparral can survive under these conditions. On the north-facing slope where moisture lasts longer, trees thrive.
Sunol is one of the most beautiful parks in the Bay Area.
Truly, Sunol is lovely!
I had been literally dreaming of a place like this for the longest time. When I first saw Sunol, I recognized it and knew I’d arrived.
Wow, very cool!
