Field notes
The record separates gradual movement from episodic collapse: a quiet year may approach zero, while a saturated winter can produce a metre-scale step. Four fixed rebar markers support repeat observations, including a vertical active face, an overhang expected to fail within two seasons, and a slower boulder-clay slope. The page attributes the main failure plane to water gathering where low-permeability clay meets weaker laminated silts.
