Utforskning av et nytt gangsystem i Lullehačorrugrottan ved Torneträsk

Abstract

The Lullehačorrugrottan cave in the Torneträsk area of northern Sweden was originally surveyed to 1145 m by Gunnar Rasmusson 50 years ago. Later surveys in 2003 added 267 m of new cave passages (grade 2). In March 2007 a Norwegian / Swedish joint expedition explored and partly surveyed the continuation of one of the passages discovered in 2003. The benefit of winter caving is low water level, because of no liquid precipitation for half a year. 87 m passage (discovered in 2003) was surveyed to grade 5 and an estimated 85 m completely new passage was surveyed to grade 2. This article focus on the exploration of this new passage and the challenges the expedition faced in remote areas and arctic winter.
