This is the east rim of Dry Canyon. I include this shot to illustrate its steepness, and rockiness, relative to most of the facing West rim. There’s a reason for this. The Canyon cut by the Paleo Deschutes river followed a seam created by a younger Newberry volcano flow that pushed the Deschutes Westward up against the older flows is showing from many vents that comprised the Deschutes Formation. This also illustrates the fact that our weather tends to blow in from the west, swinging north and south, and only rarely from the east. The soil in the canyon is mostly blown in from the adjacent landscape and spilling in over the west rim as accumulated there helping determine the soil conditions for what will grow there.
