the oppposite OS the base of a mountain is the summit
The opposite of the base of a mountain is its peak or summit. The base of a mountain refers to the bottom or lowest point of the mountain, while the peak is the topmost point. It is the highest elevation of the mountain where the slopes converge.
The opposite landform could be a lowland. Or in the ocean, a trench, deep or abyss. In mountains, the natural opposite of a peak is a valley. The opposite structure of a mountain, where the elevation is lower rather than higher, is a crevasse or chasm.
I'm assuming that you would be referring to the "peak" of a mountain. The peak of the mountain is generally the tallest point; thus opposite of the base.
an antonym for that would be at the mountains base
A gorge.
