Surface hoar

Layers of concern were Surface hoar down 40cm (10mm) and 55cm (4mm) Moderate Column test results showed sudden planer character on 10mm surface hoar, a slight assist after the fracture initiation had the slab cash register into the pit. Extended column test showed propagation on moderate taps. Moderate column test results showed resistant planer character on 4mm surface hoar. Hard Extended column results showed non propagation on this layer with fracture initiation Dug down to 85cm above ground and showed progressive resistance and no layers of concern below. Open tree line terrain. Avoided connected features and terrain steeper then 30 degrees with uncertainty of developing slab. Acmg asg
