The Twin seams pass below river level not far west of their exposure on the shore of the river. Eastward they rise in the high canyon cliff, reaching the top near Boring Point where they are concealed. It is inferred that they extend across a high bench to the Galloway slope, up that slope, and into Heron Creek Valley. These seams can be found anywhere by opening a trench just above (that is on the down-dip side of) the outcrop of the Heron Creek sandstone. Knight Seam The Knight seam immediately overlies the Canyon sandstone. Indeed the line at the top of the outcrop of this sandstone in Figure 10 can be taken as the outcrop of this seam. It is exposed at river level on the north- east of Cust Island. There it consists of 3 feet of coal of low volatile bituminous rank. The outcrop can be followed up the canyon wall, across an old back channel excavated at an early stage of canyon development, and up the Galloway slope. It is only exposed, however, on the shore of the river and in the canyon wall. It was opened in a trench excavated just above the outcrop of the Canyon sandstone at the top of the Galloway slope. At this place the seam had increased to 3-9 feet in thickness. Both on the shore and in the trench on the Galloway slope the coal is of medium volatile bituminous rank.
