How is a sense of curiosity created through different poetic devices in ‘Climbing My Grandfather’?

The poet is using imagery to conjure up the majestic mountain of a man who is his grandfather. He states that his grandfather wears 'old brogues, dusty and cracked', implying that this is a man who has worked arduously in his lifetime.

Using the metaphor of climbing a mountain as getting to know his grandfather creates interest for the reader. Will the poet make it to the summit? What would he experience there?
