Below TL terrain was comprised of mainly full-depth facets. Average HS 50 cm. Exposed terrain was stripped or up to 1.5M windslab resting on large basal facets. Tests showed very easy failures at the DH. Several ECTPV were observed. We observed no collapsing and only very localized underfoot cracking. M/F layer was only observed below TL.
