Since 1952 the author bas followed the development of slopes in the trough valley of Kârkevagge in Swedish Lappland. The momentary mass-movements (rockfalls, eroding snow avalanches, mudflows, earth-slides) have been recorded by (1) direct observations, (2) iventories of the fresh debris deposited upon snow at the end of the spring, or (3) upon vegetation in summer, (4) comparison between old and new photographs of the same slope, (5) measurements of the quantity of fresh rockfall debris upon sack carpets. The more continuous processes (talus-creep, solifluction) have been recorded by checking the annual position of wooden stakes and painted boulders (fig. 5).
In this article some results from three slope sections in Kârkevagge are given. (a) A steep rockwall with a gullied talus, characterized by rockfalls, mudflows and gullying (fig. 3). (b) A steep slope with a small stream, where snow avalanches are important for the morphology (fig. 4). (c) Recording of talus-creep on a talus cone and solifluction on a till-covered slope (fig. 5).
