The tabulated results for this survey are contained in Table 19. This area continues to improve over time exhibiting increased stability and vegetative growth. However, an area of the terrace on a curve above the rock habitat ("Stonehenge") has failed resulting in new gullies forming on the slope immediately below. The Tl 1 terrace and the associated gullies are scheduled for repair in 2004.

In 2002, corrective measures included ' contour furrowing and seeding gullies located at the southwest edge of the block. No corrective measures planned as a result of the inventory. ' 14
