Abstract
This paper gives a condensed account of the geodetic measurements carriedout at Dösen rock glacier during the last 0 years (995–05). The measurementswere taken on an annual basis in order to determine the mean annual flow velocity ofthe rock glacier. The long-term monitoring program was interrupted only once, i. e. in00. The geodetic network comprises 07 observation points located on the rock gla-cier (4 of which have been stabilized with brass bolts) and 7 stable reference pointssituated in the vicinity of the rock glacier. In 04 traditional surveying using a totalstation was replaced by satellite-based surveying (real-time kinematic - global naviga-tion satellite systems, RTK-GNSS). The flow velocities obtained reveal very well thekinematic behaviour of Dösen rock glacier over the course of time and are an excellentbasis for subsequent climate change studies. The mean annual flow velocity of the fastest points varied between .0 and 5.6 cm/a during the observation period. Thehighest flow velocities (up to 65.9 cm/a) were recorded for 04–05, confirming theongoing speed-up of this rock glacier
