Though I did not succeed in ascend-ing the rugged cliffs, I had no doubt that the lower glacier, from itscolour and the steepness and contraction of the gorge above it, is atrue glacier remanie, and like the Suphelle glacier described by Forbes{Norway and its Glaciers, p. 149), is quite disconnected, at least insummer, from the snow-fields above. 132 GEOLOGICAL SKETCHES.

Numerous ancient mare vi] OLD GLACIERS OF NORWAY AND SCOTLAND. 133 terraces, especially the same two prominent ones alreadymentioned, may be traced along the sides of the JokulsFjord. The lower of these runs at a level of about 60 feet,the higher at about 152 feet (aneroid measurement) abovehigh-water mark. The upper is especially marked, oftenrunning as a shelf cut out of the rock. This feature wasnoticed along many parts of the Norwegian coast, even (asin the Jokuls Fjord) in sheltered places where wave actioncannot be supposed ever to have been very strong. Asthe date of these rock-terraces probably goes back into theglaci
