“…In the valley of Kärkevagge, some 20-km west of Abisko, a research group from the USA led by C. Thorn from University of Illinois, has been studying weathering and soil formation processes for more than 10 years. They have shown that the chemical weathering by the transport of solute loads in river systems in Kärkevagge and other cold areas must be ranked highly in importance compared with the dramatic, but often highly localized contributions from alpine mass wasting processes (Dixon et al 2002). They have also shown that there is sufficient pedological evidence to support the argument that chemical weathering is of major importance even in cold areas (Darmody et al 2008).…”

This article gives an overview of the studies on the environment surrounding the Abisko Scientific Research Station in Swedish Lapland. The long-term monitoring of the Station on processes related to the climate, and to the physical, biotic, and chemical environmental conditions is particularly addressed. Some variables are recorded since more than 100 years. The obtained data in combination with results from short-term studies and manipulation experiments are important to understand past and future conditions of the ecosystems. This has practical applications for the planning of tourism, transports, reindeer herding, and for societal purposes.

“…Similar geographic variability in rock coatings occurs outside of deserts, for example, in a climatic transect from the Khumbu of Nepal to the rainshadow in the Tibetan Plateau (Dorn, 1998). Although there has been an increase in the understanding of rock coatings in humid areas (Reams, 1990;Darmody et al, 2002;Dixon et al, 2002;Arocena and Hall, 2003), detailed studies establishing contemporary relationships (Dorn, 1990) are largely lacking in wetter regions (Krumbein and Urzi, 1993). We hope that this study also stimulates research on the relationship between catena changes in humid-area rock coatings and the manner in which prehistoric peoples altered stone.…”

A new strategy for analyzing the chronometry of constructed rock features in deserts

The western Great Basin contains thousands of constructed rock features, including rock rings, cairns, and alignments. Unlike subtractive geoglyphs, such as the Nasca Lines of Peru, that remove desert pavement, these surface features alter the location and positioning of cobble-to bouldersized rocks. The chronology of surface rock features has remained unconstrained by numerical ages because no prior chronometric approach has been able to yield age control. We propose a new strategy for studying these features by analyzing anthropogenic modifications to rock coatings, an approach that permits the use of several dating methods, two of which are assessed here: radiocarbon dating of pedogenic carbonate and rock-varnish microlaminations. Initial results from Searles Valley, eastern California, suggest that constructed rock features may be as old as early Holocene and terminal Pleistocene. Archaeological surveys of desert areas would be greatly enhanced if they noted altered positions of rock coatings.
