M. B. Edwards comments: Of all the geological occurrences he had seen, this was the most remarkable and revealing. For him it was a spiritual place, and the journey was a pilgrimage; he used this word himself. This was now the seventh time he was making this journey. Thus wrote Rosendahl (1945, p. 22; my translation from Norwegian) about the geologist Sederholm. Decades later, after dozens more publications of innumerable additional outcrops, the ‘Reusch's Moraine’ exposure of upper Proterozoic glacial tillite resting on a glacially striated pavement (Reusch, 1891) remains unique and significant.

Writing about this exposure, Jensen & Wulff-Pedersen (1996) concluded ‘There is no evidence for glacial origin or contribution for the diamictite material’ (p. 137) in the Bigganjargga tillite. This discussion explains why I disagree with their conclusions.
