It's a good day trip hike up Mt Takao. Get the Mt Takao discount ticket (round trip train ticket + round trip/one-way cable car/chair lift ticket) and on your way. Mt Fuji is visible when you reach the summit. I took the one-way cable car up and came down by trail 4 which would encounter a suspension bridge. Overall a...
An alluvial plain is a largely flat landform created by the deposition of sediment over a long period of time by one or more rivers coming from highland regions, from which alluvial soil forms.
The open plain allows the water to slow down and spread out, leaving alluvium behind. As the water slows down, the harder-to-move pieces of alluvium, usually the boulders and gravel, are the first to stop. Further down the alluvial fan, the lighter sediment, like silt and sand, is deposited. Alluvial fans have some similar characteristics. The pointy part of the triangle, where the water and sediment have come out of the narrow passage, is called the apex or sometimes the fan head. The bottom part of the triangle, where the mixes spread out, is the apron, or tail, of the alluvial fan.
