Since the topography of Mount Rainier is very jagged and uneven, the glacier is warped and twisted during its descent northward down to its terminus at about . From there, the glacier ice falls off the cliff and tumbles down the steep Mowich Face; eventually, this ice contributes to the large North Mowich Glacier at an elevation of .
Given the rugged terrain of Mount Rainier, the glacier is subjected to considerable deformation as it flows northward toward its endpoint around . From there, the glacier's ice plunges down the steep slope of the Mowich Face; eventually, this ice contributes to the substantial North Mowich Glacier situated at an elevation of .
