A stake in the middle of the southern half of the line is or seems to be further west than the others, but this may be due to original setting. At the base a second ridge has risen south of that noted on p - 44. This is larger, longer and higher, the crest being 15 feet above level of late ice in its highest part. The stoss (glacier) side of the ridge shows beautifully the direction from which the pressure came, being flexed back at top to and beyond the vertical On the distal side of the ridge the ice has been bent down below the general level of the lake surface forming an open hollow 1.5 - 2 ft deep. A similar hollow was formed on the proximal side of the ridge, but water got in and it is now full of new ice. This ridge extends from the north to or beyond the middle of the front of the glacier. Apparently it is the result of movement which has taken place within the last four weeks, amounting to at least 10 feet horizontally. Relations are approximately as represented in the following section -
