A grand view of the ice complex at the “dogleg” of Muir inlet. Riggs Glacier’s tidewater front separated from Muir Glacier in 1961 and was still calving into the sea in 1967. At that time, McBride Glacier ice was being contributed to Riggs from the right, but that soon would end as McBride retreated in its inlet and its ice level quickly dropped. Notice, however, that in the McBride tongue, older ice was being overrun by a pulse of newer ice (demarcated by a black moraine) suggesting that McBride had just made a small pulse forward in its general retreat.
