| Features of the upper course | A waterfall( Erosion of the soft rock that leads to step due to the remaining hard rock.The hard rock is eroded causing a drop. The undercut erosion leads to collapsed rock to swirl and form a plunge pool by abrasion. Retreat = gorge) Interlocking spurs -lack of power to erode laterally so it winds around hilss |
