No stability test done, as thick and very hard (K and P) layers were present and made digging very time consuming.

ECTN22@77 propagated 38 cm. BUT, source of error: a branch from a bush hindered proper isolation of the block at that particular test.

When pulling column with shovel from behind, the column broke at 51cm and 74 cm. Facets was not observed in associated MFcr layers, but hardness (P-) suggests that bindings in the 50 cm MFcr layer has been more weakened than in the layer at 74 cm. Thus, I consider the layer at 50-44 cm to be the weakest layer.
