Just north of Tacoma?

I looked at my downloads from the February 2010 picture, and since we did not go north of Cascade Wye and in terms of where my image fit in with others, I am guessing this is somewhere between Tacoma and Ah Wilderness. I have a vague memory that of being told the curves resulted from repairs after the serious flooding and washouts in the later years of DRGW operations. Google satellite views don't show that part of the railroad well because of morning shadows. But speaking of Google satellite views, checkout the 3D version of the cliff above "cement wall" (just south of Cascasde), the perspective (and distortion) is wild.
