Lumbering giant? Ancestral image? Data structure. Sappy sort.

I reign without a crown, Yet kingdoms mark my flight. I wield no blade nor throne, But rule the silent height. My gaze can measure miles, My shadow silences the small. I rise where storms are born, Unchallenged over all. What am I?

In gardens, I hide beneath the earth's crust, Orange and crunchy, a veggie you trust. Bunnies adore me with every bite, A root that's both savory and bright.

The shape of the moon Or fingernail clips A flaky treat to eat Between orange juice sips

Child of the glacier, now wed to the river and seas, wear your towering crowns of earth with pride. Remember fondly your landlocked siblings, and gather up your hanging valleys. Now, run, Child, headlong into the loving embrace of the basin, filled to the brim with brackish water.
