Basal Sliding and Movement Near the Margin of the Glacier Østerdalsisen, Norway
Observations in and around natural caves beneath the glacier Østerdalsisen in 1961 and 1962 indicated that, within the marginal zone, basal sliding played a major part in the movement measured at the upper surface. Sliding rates apparently were influenced by the availability of water at the glacier....
