SierraElectrician, what tree species are those?

In my last photo, the trees in front of the old house are giant redwoods planted about 1860, the same time the derelict house in the picture was built and when they were first brought back to Scotland from California (there's been buildings here since at least 1300). We've had more snow in the last few days, maybe the last of the roof will fall in!
