Vertical movements of boulders in a subnival boulder pavement at 2800 m a.s.l. in the Alps (France)
Abstract Vertical movements of boulders within a subnival boulder pavement were measured at 2800 m a.s.l. in the Alps over a period of 10 years. It was demonstrated that some boulders are undergoing sinking and others upheaving. The upheaving occurs in autumn during ground freezing, while the sinkin...

Summary: | Abstract Vertical movements of boulders within a subnival boulder pavement were measured at 2800 m a.s.l. in the Alps over a period of 10 years. It was demonstrated that some boulders are undergoing sinking and others upheaving. The upheaving occurs in autumn during ground freezing, while the sinking of boulders probably occurs in springtime when the ground temperature is below 0 °C under the snow patch. |
