Twidale & Bourne: Geomorphology of The Humps, Hyden 
Figure 2. Southwesterly view of The Humps showing the 'entrance' valley which drains the northern sector of the hill, and its stepped 
morphology. The prominent flared slope high on the hill is developed below Level I, a stand of trees, on the right skyline, amidst the 
weathered and fractured sheet structure marks Level II. Level III is not preserved in this sector of the hill so that a gentle incline leads 
down from Level II to Level IV, the dry grassed areas and rock platforms of the present plain level.
