This is, in fact, a rather odd bit of geography. Although it is officially part of the Sierra Nevada, and is underlain with Sierra granite, the top few hundred feet of it are the remains of an ancient lava flow that is really part of the Cascade system. East of the Feather River- the west fork of its north branch is less than a mile east of my house- the mountains rise precipitously, but here we have only a gradually rising piedmont cut with shallow stream valleys. The other odd thing is that the ridge runs downward mostly toward the south, rather than the west. It sticks out from the Sierra several miles, sort of like a knot on the head of the range. The southern exposure, volcanic soil, and relatively gentle topography are what made it a good area for apple orchards. They also account for the fact that we don't have the swift streams running through rugged canyons which are characteristic of most of the Sierra.
Watching the movie, I found myself wishing that we had one of those streams here. The Feather River is one of those streams, of course, but it is nearly inaccessible at any point near my house. I sometimes wish that they would develop the patch of forest on the eastern edge of town, since that would require the construction of roads running close to the river. Strange as it may seem, though I have lived here for almost sixteen years, I have never seen the river except in brief glimpses from a moving car on the highways north and south of town, where they run along the edge of the canyon. The only flowing water I see on a regular basis is in the small streams at the bottoms of the larger arroyos that run through the town. Most of the year, they are little more than brooks. Someday, I must arrange to get close to some moving water. The monotony of the local landscape is boring me.
