(a) Multi-modal deposit
(clast size ranges from boulders to silt) containing angular boulders of
shale eroded from local bedrock. Note clean sand (arrowed) beneath protecting
boulder. Anakroken, Sweden.

(b) Graded sand, deposited
from suspension, and diamicton, deposited by debris flows resulting from
intermittent failure of underconsolidated beds of suspension deposits.
Chicoutamie, Quebec.
