Jetsam Moraine () is a thin, sinuous medial moraine that arcs smoothly for from a point near Mount Razorback to beyond the far (northeastern) side of Black Pudding Peak, in the Prince Albert Mountains of Victoria Land, Antarctica. Its curved trajectory marks the contact between Benson Glacier ice and that of Midship Glacier. It was so named by a 1989–90 New Zealand Antarctic Research Programme field party from association with the Flotsam Moraines and because all supraglacial moraines are "floating" on the glacier ice, and drift
Cascade subcontinent that docked with Washington about 50 million years ago as the entire continent of North America moved west across the ocean. The Alps were heavily eroded by glaciers in the last ice age. The Vashon lobe of the ice sculpted Rattlesnake Ledge, steeply carved the east and west sides of Squak Mountain, and deposited a large erratic on Cougar Mountain, Fantastic Erratic.
Cedar Butte rises abruptly from the moraine between Rattlesnake Ledge and the absolute front of the Cascades. It is sometimes considered part of the Issaquah Alps but it
