Titles.
11:10:52 Animated diagram showing chain of life - raw materials, energy, plants, top soil, organization, water, forests.
11:11:30 Ocean, clouds moved by air currents into mountain range - dramatic cloud formations & rain shower. Dry area inland - stream running from mountain & through forest.
11:12:39 Forest floor w/ ground plants absorbing water like sponge. Mountains; trees; snow melting slowly on wooded area of hillside - burned area w/ almost no snow; CUs rainwater running off barren land.
11:13:44 Shrubs & vegetation protecting soil.
11:14:02 Studio cross-section model of soil w/ water pouring - one side ‘Forest Absorbs’, the other ‘Bare Surface Sheds Rain’ - moisture on protected side filters to water table & spreads by capillary action.
11:14:26 Farm field w/ irrigation ditch; LS of haying of farm meadow-land in shadow of mountain - alfalfa crop harvested.
11:14:47 Rapids, churning mountain river - moose wandering in grassland.
11:15:10 Tree gnawed by beavers. Beaver on dam. Reflections.
11:15:35 Large man-made dam & huge reservoir. Green irrigated land downstream next to desert - not enough water.
11:16:17 Mountains, snowfield meltes into springs & brooks - into rivers. Streams. Mountains of Continental divide - splits water off in different directions - irrigating fruit trees in California; lands of Mississippi Valley irrigated; south into Rio Grande.
11:17:32 Fertile San Luis Valley - irrigation canals & ditches thru fields.
11:18:00 Map of US showing water drainage thru states.
11:18:25 Fertile cropland farmland; dust-devil blowing to create Dust Bowl; silt & muddy river. Tree felled,marshes drained, soil tilled; combine harvester working. Geyser & mountains. The End.
