Trust Lake chutes

ACC AST2 course. Our group did several CT’s and ECT’s. All with similar results. Easy failure at 35cm over surface hoar. Moderate failure at 80cm. ECT showed propagation at 35cm. One group dug to ground and was able to see failure at ground level. Our Rutschblock Test was a 3. We were on a 32 degree slope. Minus 16 degree air temp. North aspect. Signs of natural activity.
