Myoko Suginohara Ski Resort Mountain
The landform the resort sits on: the shape of the hill beyond the pistes, how steep it gets, and where it stands among the mountains on JapowDB.
One hillside, and it falls away to the south-east.
Where this vertical sits among the mountains on JapowDB
1,124 m, more than 33 of the 34 mountains on JapowDB.
The mountain
三田原山 (Santabara-yama)
- Above it
- 妙高山 (Myōkō-san) 2,454 m
- Landform
- The outer rim of Myoko's collapsed caldera. Santabara was the earlier volcano, reckoned at 2,800 to 3,000 m before it fell in, taller than Myoko stands today. The runs drop down the outside of what is left of it.
- Rock
- Andesite and basaltic andesite lava with its own debris high up, late Pleistocene. The lower mountain is the same rock but Holocene, younger material that came down afterwards and settled where the ground eases off.

Measured
01
Which way it faces
Faces south-east.
Most of the mapped runs fall away toward the south-east.
02
How steep it gets
That steep ground sits high on the mountain.
Its steepest pitch measures 34.7°.
Its steepest tenth is steeper than 5 of the 34 mountains here that carry pitch data.
14.5° the steepest tenth of runs
03
How varied it is
Its runs range from 5.1° to 17.8°.
Half of them are gentler than 12.6°. Each mark is one run.
That spread is wider than 8 of the 34 mountains here that carry pitch data.
04
What grows on it
Mostly deciduous: broadleaf woods and larch. They stand bare through the winter, so you can see a long way into them.
