Mountains are the world's best pre-made metaphors for struggles, challenges, and hierarchies. What's even better, they're almost universal. There are mountains everywhere, and just about everyone has seen a mountain of one size or another at least once in their life, and if not a mountain, then at least a decent sized hill or upland.
The mountain, therefore, is a wonderful metaphor for poker (because it is a wonderful metaphor for almost everything). Poker embodies the ideas of challenge, struggle, and hierarchies. In fact, poker is a sort of the "king of the mountain" game involving cards, chips, and manipulation. The guy or gal with the biggest pile is the king or queen of the mountain, and everyone else is trying to knock him or her off of that mountain. That's just on the micro scale. The same thing is happening at tournaments and in the greater poker community. Everyone is trying to become king or queen of the mountain.
To get there, you have to struggle and face down challenges. That's where the whole "climbing the mountain" metaphor comes in. Poker is like climbing a mountain, just you're also tossing your opponents off the side on the way up.
