1. Streams carried rock debris down slope to be deposited in nearby lowlands. 2. These deposits of rock debris are called lobate debris aprons ( LDAs ). 3. Streams carried rock debris downslope to be deposited in nearby lowlands. 4. Soil and rock debris lubricated by the melt-water flow easily over the underlying frozen subsoil. 5. The summit is strewn with rock debris and has a trig point and a cairn. 6. In the pictures, this section of the glacier is gray with rock debris and has few crevasses. 7. Shaken by an earthquake, the north face of the mountain collapsed in a massive rock debris avalanche. 8. Braided meltwater streams heavily loaded with rock debris continually shift and intertwine their channels over valley floors. 9.
