So, from now on we will be adding technical words dealing with skiing in Japan as well as how to order your favorite beer, or pick up the ladies. If you have any specific requests, then please ask. This will be an ongoing project, so please excuse the limited info at the beginning.　PS, the previous list that we had created over at Snow Japan seems to now be a "problem to look up in the database." Quite funny how I look up stuff, and the forums continuously go offline. Coincidence?

谷底 tanizoko -the bottom of a ravine/valley floor

山を下りる(yama wo oriru): coming down a [the] mountain

山頂 (sanchou) summit, mountaintop

this is more specific than

choujou is a more general term
ie you can use choujou for the top of a hill but sanchou is more mountain peak-specific.

there's 1 more word for summit, 頂 itadaki but that is used in poems, etc (in other words, forget about it!)
