a glacier's gravel diary, dumped wherever the ice finally lost its nerve.
means A mass of rock, gravel, and debris that a glacier picks up, carries along, and deposits — forming ridges or mounds that mark where the ice once was.
from From French moraine, borrowed in the 18th century from a Savoyard (Alpine French) dialect word for the rubble heaped along the edges of glaciers — itself possibly from a Romance root meaning 'snout' or 'muzzle,' the way the debris piles up at a glacier's blunt leading end. The Alpine peasants who lived beneath the ice had the word long before geologists came to claim it.
