This oblique southeasterly view of the Sentinel Mountains from Google Earth shows the general area from a little higher than roadside level; that's the Alcan, AKA Highway 97. The topography of the same area, looking straight down and with the north arrow cocked to the right, can be seen here in The Atlas of Canada.
The picture I took looks like this; it corresponds with the two central peaks from the Google Earth image, with just a little of the pyramidal-shaped range-front hill on the far left.
Drawing on a composite set of photos, I came up with this pen-and-ink interpretation, which shows the general flat-lying nature of the sedimentary horizons away from the range front and to the east. The beds are then tilted into a dip slope right along the range front, forming a set of triangular-shaped facets, which I described more completely earlier. If you look carefully at the photo and the sketch, you'll see that they match up imperfectly - the sketch makes the farther hill appear a little larger than life. It is a cartoon.
