It is extremely dangerous to climb a snowy mountain, for you may slip and fall to your death.
You should never attempt to climb a snow-covered mountain because it is very dangerous.
Never ever try to climb a snowy mountain because it is extremely dangerous.
You may use a compound sentence in explaining just why it is extremely dangerous to climb a snowy mountain. The compound sentence may use the conjunction 'for' to link the two independent clauses which have related ideas, in this case, it is 'extremely dangerous', and, 'slip and fall to your death'. The adjective 'snow-covered' means 'snowy'. The verb to 'attempt' means to 'try'.
So, you may say:
It is extremely dangerous to climb a snowy mountain, for you may slip and fall to your death.
or
You should never attempt to climb a snow-covered mountain because it is very dangerous.
or
Never ever try to climb a snowy mountain because it is extremely dangerous.
雪山登山がなぜ極めて危険だということを説明するために、複文を使うといいでしょう。
複文は、「for」という接続詞を使って、関連する2つの節をつなげます。
この場合、「extremely dangerous」と「slip and fall to your death」をつなげます。
形容詞「snow-covered」は「雪の」という意味です。
動詞「attempt」は「試みる」という意味です。以下のように言えます：
It is extremely dangerous to climb a snowy mountain, for you may slip and fall to your death.
（滑って転び死亡事故にもつながるので、雪山登山は極めて危険です。）
You should never attempt to climb a snow-covered mountain because it is very dangerous.
Never ever try to climb a snowy mountain because it is extremely dangerous.
（極めて危険なので、雪山登山は絶対やめるべきです。）
The mountain is snowy, it will be dangerous to climb.
The snow makes the mountain dangerous to climb.
The mountain is snowy' - starting the statement with this description helps to set up the reason for stating the mountain is dangerous. If the mountain is dangerous to climb even without snow, you could change the statement to 'The mountain is snowy, it will be even more dangerous to climb'.
'The snow makes the mountain dangerous to climb' means that it is the snow that causes the danger, not the mountain itself. Again, if you would like to emphasise that the mountain is already dangerous to climb, without the snow, but it is MORE dangerous to climb with the snow on it, you could day 'The snow makes the mountain even more dangerous to climb'.
「The mountain is snowy」- この記述から文をはじめることで、なぜその山が危険かを示す理由を述べることができます。
もし、登山が雪無しでも危険ならば、文を以下のように変更できます。
The mountain is snowy, it will be even more dangerous to climb.
（山は雪に覆われているので、登山は更に危険です。）
「The snow makes the mountain dangerous to climb」は、雪が危険で、山そのものではないという意味です。
また、雪無しでも山は危険だが、雪が降ると更に危険になると強調したい場合は、以下のように言えます。
The snow makes the mountain even more dangerous to climb.
（雪が降っていて、登山は更に危険です。）
おっしゃられている内容は、以下のようにも表現できると思いました(*^_^*)
Climbing snowy mountains is dangerous.
「雪山を登ることは危険だ」
以上ですm(_)m
