The Van Trump Glacier is actually a scattering of glaciers and snowfields located on the southern flank of Mount Rainier in Washington.
 Named after P. B. Van Trump, who was part of an early ascent of Mount Rainier, the glacier covers 0.2 sqmi and contains 500 million ft (14 million m) of ice.
 The glacier is located between the Wilson Glacier to the east and the Kautz Glacier to the west.
 The elevation of the scattering ranges from 7000 ft at the lower end to 9800 ft on the upper reaches of the glacier.
 Meltwater from the glacier drains into the Nisqually River.
Van Trump Falls is a waterfall on Van Trump Creek in Pierce County, Washington.

The Kautz Glacier is a narrow glacier on the southern flank of Mount Rainier in Washington.
 Named for August Kautz, who is sometimes credited for the first ascent of Mount Rainier, covers 1.8 sqmi and contains 7.8 billion ft (221 million m) of ice.
 Upper Kautz Glacier extends south from the summit ice cap to Kautz Ice Cliff at about 11700 ft .
 Immediately west of the main ice cliff, the glacier continues down Kautz Chute which terminates in another ice cliff just above the lower Kautz Glacier at 10800 ft .
 Usually reached by a short descent from Camp Hazard at 11300 ft on Wapowety Cleaver, climbers following the Kautz Glacier climbing route ascend this chute to the upper glacier.
