Kiroro Snow World 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.

余市岳 (Yoichi-dake) 1,488 m
Landform
You ski the sides of two volcanoes here. Asari-dake is a basalt cone, and its summit is so flat that skiers call it the airfield. The lifts stop at 1,180 m, about a hundred short of that summit, and much further below Yoichi-dake.
Rock
One rock from top to bottom: andesite and basaltic andesite lava with the debris it threw out, Miocene to Pliocene. Sampled at the top of the lifts and again halfway down, it does not change, and that is the plainest reason every slope here leans the same way.

How steep it gets

That steep ground sits high on the mountain.

Its steepest tenth is steeper than 10 of the 34 mountains here that carry pitch data.

How varied it is

Its runs range from 2.9° to 17.9°.

Half of them are gentler than 9.9°. Each mark is one run.

That spread is wider than 14 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.
